You can modify general in-path and out-of-path interface settings in the Optimization Service - General Settings Page.

NOTE: You were prompted to enable in-path or out-of-path support when you completed the installation wizard. This section describes how you can modify these settings.

The following types of deployments are available to you:

 Physical In-Path. The HP EFS WAN Accelerator is physically in the direct path

between the client and server. The clients and servers continue to see client and server IP addresses. Physical in-path configurations are suitable for any location where the total bandwidth is within the limits of the installed HP EFS WAN Accelerator.

 Virtual In-Path. The HP EFS WAN Accelerator is virtually in the path between

the client and server. This differs from a physical in-path in that a packet redirection mechanism is used to direct packets to HP EFS WAN Accelerators that are not in the physical path. Redirection mechanisms include Web Cache Communication Protocol (WCCP), Layer 4 (L4) switches, and Policy-Based Routing (PBR). In this configuration, clients and servers continue to see client and server IP addresses.

 Out-of-Path. The HP EFS WAN Accelerator is not in the direct path between the

client and the server. Servers see the IP address of the server-side HP EFS WAN Accelerator rather than the client IP address, which might impact security policies. An out-of-path configuration is suitable for data center locations where physically in-path or virtually in-path configurations are not possible.

For detailed information about in-path and out-of-path deployments, see the HP StorageWorks Enterprise File Services WAN Accelerator Deployment Guide.

To enable in-path or out-of-path support

If you have an HP EFS WAN Accelerator that contains multiple two-port or four-port bypass cards, the Management Console displays options to enable in-path support for these ports. The number of these interface options depends on the number of pairs of Local Area Network (LAN) and Wide Area Network (WAN) ports that you have enabled in your HP EFS WAN Accelerator.

2. Use the controls to complete the configuration, as described in the following table.

Control Description

In-Path Enable In-Path Support. Specify this option to enable optimization on traffic that is in

the direct path of the client, server, and HP EFS WAN Accelerator.

Reset Existing Client Connections on Startup. Specify this option to enable kickoff. If you enable kickoff, connections that exist when the HP EFS WAN Accelerator service is started and restarted are disconnected. When the connections are retried they are optimized.

Generally, connections are short lived and kickoff is not necessary. It is suitable for very challenging remote environments. For example, in an environment with 128 kbps and 1.5 seconds of latency, you might want to abort an HTTP download so that your traffic is optimized, whereas in a remote branch-office with a T1 and 35 ms round-trip time, you would want connections to migrate to optimization gracefully, rather than risk interruption with kickoff.

NOTE: Do not enable kickoff for in-path HP EFS WAN Accelerators that use autodiscovery or if you do not have an HP EFS WAN Accelerator on the remote side of the network.

Enable L4/PBR/WCCP Support on Interface <interface_name>. Specify this option to enable optional, virtual in-path support on the named interface. External traffic redirection is supported only on the first in-path interface. The following redirection methods are available:

• Layer-4 Switch. You enable Layer-4 switch support when you have multiple HP EFS

WAN Accelerators in your network, so that you can manage large bandwidth requirements.

• Policy-Based Routing (PBR). PBR allows you to define policies to route packets

instead of relying on routing protocols. You enable PBR to redirect traffic that you want optimized by an HP EFS WAN Accelerator that is not in the direct physical path between the client and server.

• Web Cache Communication Protocol (WCCP). If your network design requires you

to use WCCP, a packet redirection mechanism directs packets to HP EFS WAN Accelerators that are not in the direct physical path to ensure that they are optimized.

For detailed information about configuring Layer-4 switch, PBR, and WCCP deployments, see the HP StorageWorks Enterprise File Services WAN Accelerator Deployment Guide.

Enable Optimizations on Interface <interface_name>. Specify this option to enable in-path support for additional bypass cards.

If you have an HP EFS WAN Accelerator that contains multiple two-port or four-port bypass cards, the Management Console displays options to enable in-path support for these ports. The number of these interface options depends on the number of pairs of LAN and WAN ports that you have enabled in your HP EFS WAN Accelerator.

The interface names for the bypass cards are a combination of the slot number and the port pairs (inpath<slot>_<pair>, inpath<slot>_<pair>). For example, if a four-port bypass card is located in slot 0 of your appliance, the interface names are: inpath0_0 and inpath0_1. Alternatively, if the bypass card is located in slot 1 of your appliance, the interface names are: inpath1_0 and inpath1_1. The maximum number of pairs is six, which is three four-port bypass cards.

For detailed information about installing additional bypass cards, see the HP

StorageWorks Enterprise File Services N4c WAN Accelerator 4-port NIC Installation Guide.

Control Description

Out-of-Path Enable Out-of-Path Support. Specify this option to enable out-of-path support. You

enable out-of-path support on server-side HP EFS WAN Accelerators only.

NOTE: If you set up an out-of-path configuration with failover support, you must set fixed target rules that specify the master and backup HP EFS WAN Accelerators. For detailed information, see “Setting In-Path Rules” on page 25.

Connection Limit Per Source IP Connection Limit. Check this box to limit half-opened connections on a

source IP address initiating connections (that is, the client machine). Set this feature to block a source IP address that is opening multiple connections to invalid hosts or ports simultaneously (for example, a virus or a port scanner). This feature does not prevent a source IP address from connecting to valid hosts at a normal rate. Thus a source IP address could have more established connections than the limit. The default value is

4096.

The appliance counts the number of half-opened connections for a source IP address (connections that check if a server connection can be established before accepting the client connection). If the count is above the limit, new connections from the source IP address are passed through unoptimized.

NOTE: If you have a client connecting to valid hosts or ports at a very high rate, some of its connections might be passed through even though all the connections are valid.

You set in-path configuration rules in the Optimization Service - In-Path Rules page.

An in-path rule defines the policies for intercepting traffic on specified ports for optimization.

You can create rules that apply to a single port or to a port label. A port label is a name that you assign to a set of ports so that you can reduce the number of configuration rules in your system. The following port labels are created by default in your system:

 Interactive. Automatically passes through traffic on interactive ports (for

example, Telnet, TCP ECHO, remote logging, and shell).

 Secure. Automatically pass-through traffic on commonly secure ports (for

example, ssh, https, and smtps).

 RBT-Proto. Specifies well-known ports used by the system: 7800-7801 (in-path),

7810 (out-of-path), 7820 (failover), 7850 (connection forwarding), 7860 (Interceptor appliance).

If you do not want to automatically forward these ports, click Remove Selected Rules in the Optimization Service - In-Path Rules page.

For detailed information about how to configure port labels, see “Creating Port

Labels” on page 113.

3. Use the controls to complete the configuration, as described in the following table.

Control Description

Add New Rule Type. Select one of the following rule types from the drop-down list:

• Auto-Discovery. Auto-discovery is the process by which the HP EFS WAN

Accelerator automatically intercepts and optimizes traffic on all Internet Protocol (IP) addresses and ports. By default, auto-discovery is applied to all IP addresses and the ports which are not secure or interactive. Defining in-path rules modifies this default setting.

• Fixed-Target. Use fixed-target rules to specify out-of-path HP EFS WAN Accelerators

near the target server that you want to optimize. Determine which servers you would like a particular HP EFS WAN Accelerator to optimize (and, optionally, which ports), and add rules to specify the network of servers, ports, port labels, and out-of-path HP EFS WAN Accelerators to use.

• Pass-Through. Pass-through rules identify traffic that is passed through the network

unoptimized. You define pass-through rules to exclude subnets from optimization. Traffic is also passed through when the HP EFS WAN Accelerator is in bypass mode. (Pass through might be occur because of in-path rules or because the connection was established before the HP EFS WAN Accelerator was put in place or before the HP EFS WAN Accelerator service was enabled.)

• Discard. Packets for the connection that match the rule are dropped silently. The HP

EFS WAN Accelerator filters out traffic that matches the discard rules. This process is similar to how routers and firewalls drop disallowed packets: the connection-initiating device has no knowledge of the fact that its packets were dropped until the connection times out.

• Deny. When packets for connections match the deny rule, the appliance actively tries

to reset the connection. Deny tells the HP EFS WAN Accelerator to actively try to reset a TCP connection being attempted. Using an active reset process, rather than a silent discard allows the connection initiator to know that its connection is disallowed.

If you have an out-of-path configuration with failover support, you specify the master and backup HP EFS WAN Accelerator in the Optimization Service - In-Path Rules page.

NOTE: In out-of-path deployments, to optimize MAPI Exchange 2003 by destination port, you must define fixed-target, in-path rules that specify the following ports on the client-side HP EFS WAN Accelerator: the Microsoft end-point mapper port: 135; the HP EFS WAN Accelerator port for Exchange traffic: 7830; the HP EFS WAN Accelerator port for Exchange Directory Name Service Provider Interface (NSPI) traffic: 7840.

Control Description

Add New Rule cont. Insert Rule At. Select start, end, or a rule number from the drop-down list.

HP EFS WAN Accelerators evaluate rules in numerical order starting with rule 1. If the conditions set in the rule match, then the rule is applied, and the system moves on to the next packet. If the conditions set in the rule do not match, the system consults the next rule. For example, if the conditions of rule 1 do not match, rule 2 is consulted. If rule 2 matches the conditions, it is applied, and no further rules are consulted.

In general, you should list rules in the following order:

1. Pass-through. List the exceptions to optimization, first.

2. Fixed-target. List any fixed-targets for optimization, next.

3. Auto-discovery. Apply the default rule: optimize all remaining traffic. (The default

auto-discovery rule is listed automatically.)

28 CONFIGURING THE HP EFS WAN ACCELERATOR

Control Description

Advanced Options VLAN Tag ID. Select the VLAN identification number from the drop-down list to set

the VLAN tag identification number (VLAN ID). All specifies the rule applies to all VLANs; Untagged specifies the rule applies to non-tagged connections.

The HP EFS WAN Accelerator supports VLAN 802.1q. To configure VLAN tagging you perform the following tasks:

• You configure in-path rules to apply to all VLANs or to a specific VLAN. By default, rules apply to all VLAN values unless you specify a particular VLAN ID. Pass-through traffic maintains any pre-existing VLAN tagging between the LAN and WAN interfaces.

• You set the in-path interfaces, VLAN tag IDs to define the VLAN tag that the HP EFS WAN Accelerator uses to communicate with other HP EFS WAN Accelerator. For detailed information, see “Setting In-Path Interfaces” on page 54.

Optimization Policy. Optionally, if you have selected an Auto-Discovery or Fixed Ta rg et rule, you can configure the following types of optimization policies:

• Normal. Perform Lempel-Ziv (LZ) compression and Scalable Data Referencing (SDR).

• SDR-Only. Perform SDR; do not perform LZ compression.

• Compression-Only. Perform LZ compression; do not perform SDR.

• None. Do not perform SDR or LZ compression.

Setting an optimization policy allows you more flexibility in applying optimization techniques. For example, if you have a network that requires 45 Mbps or higher with abundant bandwidth, you do not need to perform LZ compression to obtain maximum optimization of data. Turning off LZ compression also increases throughput on large bandwidth networks.

To configure optimization policies for the File Transfer Protocol (FTP) data channel, define an in-path rule with the destination port 20 and set its optimization policy. Setting QoS for port 20 on the client-side HP EFS WAN Accelerator effects passive FTP, while setting the QoS for port 20 on the server-side HP EFS WAN Accelerator effects active FTP.

To configure optimization policies for the Messaging Application Protocol Interface (MAPI) data channel, define an in-path rule with the destination port 7830 and set its optimization policy.

HP STORAGEWORKS EFS WAN ACCELERATOR MANAGEMENT CONSOLE USER GUIDE 29

Control Description

Advanced Options cont. Neural Framing. Optionally, if you have selected Auto-Discovery or Fixed Target, you

can select a neural framing mode for the in-path rule. Neural framing enables the appliance to select the optimal packet framing boundaries for SDR. Neural framing creates a set of heuristics to intelligently determine the optimal moment to flush TCP buffers. The appliance continuously evaluates these heuristics and uses the optimal heuristic to maximize the amount of buffered data transmitted in each flush, while minimizing the amount of idle time that the data sits in the buffer. You can specify the following neural framing settings:

• Never. Never use the Nagle algorithm. All the data is immediately encoded without waiting for timers to fire or application buffers to fill past a specified threshold. Neural heuristics are computed in this mode but are not used.

• Always. Always use the Nagle algorithm. All data is passed to the codec which attempts to coalesce consume calls (if needed) to achieve better fingerprinting. A timer (6 ms) backs up the codec and causes leftover data to be consumed. Neural heuristics are computed in this mode but are not used.

• Transmission Control Protocol (TCP) Hints. This is the default setting which is based on the TCP hints. If data is received from a partial frame packet or a packet with the TCP PUSH flag set, the encoder encodes the data instead of immediately coalescing it. Neural heuristics are computed in this mode but are not used.

• Dynamic. Dynamically adjust the Nagle parameters. In this option, the HP EFS WAN Accelerator software discerns the optimum algorithm for a particular type of traffic and switches to the best algorithm based on traffic characteristic changes.

For different types of traffic, one algorithm may be better than others. The considerations include: latency added to the connection, compression, and SDR performance.

To configure neural framing for an FTP data channel, define an in-path rule with the destination port 20 and set its optimization policy. To configure neural framing for a MAPI data channel, define an in-path rule with the destination port 7830 and set its optimization policy.

Additional Options Enable Computation of Neural Heuristics. Optionally, check this box to enable

optimal packet framing boundaries for SDR.

Control Description

General Enable Latency Optimization. Latency optimization is enabled by default. Only

uncheck this box if you want disable Latency optimization. Typically, you disable latency optimization to troubleshoot problems with the system.

Disable Write Optimization. Specify this option to disable write optimization.

Disable write optimization only if you have applications that assume and require writethrough in the network. If you disable write optimization, the HP EFS WAN Accelerator still provides optimization for CIFS reads and for other protocols, but you might experience a slight decrease in overall optimization.

Most applications operate safely with write optimization because CIFS allows you to explicitly specify write-through on each write operation. However, if you have an application that does not support explicit write-through operations, you must disable it in the HP EFS WAN Accelerator.

If you do not disable write-through, the HP EFS WAN Accelerator acknowledges writes before they are fully committed to disk, to speed up write operation. The HP EFS WAN Accelerator does not acknowledge the file close until the file is safely written.

Optimize Connections with Security Signatures (that do not require signing). Specify this option to disable Windows Server Message Block (SMB) signing.

The Secure-CIFS feature enables you to automatically disable Windows Server Message Block (SMB) signing. SMB signing prevents the appliance from applying full optimization on CIFS connections and significantly reduces the performance gain from an HP EFS WAN Accelerator deployment. Because many enterprises already take additional security precautions (such as firewalls, internal-only reachable servers, and so forth), SMB signing adds little additional security, at a significant performance cost (even without appliances).

Before you enable Secure-CIFS, you must consider the following factors:

• If the client-side machine has Required signing, enabling Secure-CIFS prevents the client from connecting to the server.

• If the server-side machine has Required signing, the client and server connect but you cannot perform full latency optimization with the appliance. Domain controllers default to Required.

For detailed information about SMB signing and the performance cost associated with it, see the HP StorageWorks Enterprise File Services WAN Accelerator Installation and Configuration Guide.

HP STORAGEWORKS EFS WAN ACCELERATOR MANAGEMENT CONSOLE USER GUIDE 33

Control Description

Overlapping Open Enable Overlapping Open Optimization. This option is enabled by default. To prevent

any compromise to data integrity, the HP EFS WAN Accelerator only optimizes data to which exclusive access is available (in other words, when locks are granted). When an oplock is not available the HP EFS WAN Accelerator does not perform application-level latency optimizations but still performs Scalable Data Referencing (SDR) and compression on the data as well as TCP optimizations. If you disable this feature, the HP EFS WAN Accelerator will still increase WAN performance, but not as effectively.

Enabling this feature on applications that perform multiple opens of the same file to complete an operation will result in a performance improvement (for example, Computer Aided Design (CAD) applications):

• Optimize the Following Extensions. Specify a list of extensions you want to optimize using overlapping opens. The default values are: doc, pdf, ppt, sldasm, slddrw, slddwg, sldprt, txt, vsd, xls.

• Do Not Optimize the Following Extensions. Specify a list of extension you do not want to optimize using overlapping opens. The default values are: ldb, mdb.

NOTE: If a remote user opens a file which is optimized using the overlapping opens feature and a second user opens the same file they might receive an error if the file fails to go through a v3.x HP EFS WAN Accelerator or if it does not go through an HP EFS WAN Accelerator (for example, certain applications that are sent over the LAN). If this occurs, you should disable overlapping opens for those applications.

Enabling the NFSApplication Streamlining

To enable the NFS optimizer

You enable NFS-application streamlining in the Optimization Service - Protocol: NFS page. NFS-application streamlining provides latency optimization improvements for NFS operations primarily by prefetching data, storing it on the client HP EFS WAN Accelerator for a short amount of time, and using it to respond to client requests.

You enable NFS-application streamlining where NFS performance over the WAN is impacted by a high latency environment.

NFS file system objects have owners and permissions and NFS-application streamlining conforms to the file system permissions model by enforcing file server and volume policies. You must ensure that the policy is set correctly to Read-Only or Global Read-Write as appropriate. Setting the policy to Read-Only on a non-read-only file system results in Read-Only file system (ROFS) errors.

Enabling HSTCP Protocol Options

You enable the High Speed Transmission Control Protocol (HSTCP) in the Optimization Service - Protocol: HSTCP page.

HSTCP provides acceleration and high throughput for high bandwidth networks where the WAN pipe is large but latency is high. HSTCP is activated for all connections that have a Bandwidth-Delay Product (BDP) larger than 100 packets. HSTCP is available only on the Series 5000.

To configure HSTCP you must perform the following tasks.

Task Description

Enable HSTCP support. For detailed information, see “To enable HSTCP protocol support” on page 43.

Increase the WAN buffers. Increase the WAN buffers to 2 Bandwidth Delay Product (BDP) or 10 MB. For

detailed information, see “To enable HSTCP protocol support” on page 43.

You can calculate the BDP WAN buffer size. For example, for a link of 155 Mbps and 100 ms round-trip delay, the WAN buffers should be set to:

2 * 155 Mbps * 100 ms = 3875000 bytes

Increase the LAN buffers. Increase the LAN buffers to 1 MB. For detailed information, see “To enable

HSTCP protocol support” on page 43.

42 CONFIGURING THE HP EFS WAN ACCELERATOR

Task Description

Enable in-path support. For detailed information, see “Enabling In-Path and Out-of-Path Support” on

page 22.

Disable the Lempel-Ziv (LZ) compression and SDR in in-path optimization policies.

For detailed information about optimization policies if your WAN link capacity is 100 Mbps, see “Setting In-Path Rules” on page 25.

With SDR enabled your throughput will bottleneck between 100 and 150 Mbps, which cancels out the benefit of HSTCP. If you have an Optical Carrier3 line or faster, turning off SDR makes sense and allows HSTCP to reach its full potential. For a 2 Mbps link, regardless of the amount of latency, it is better to keep SDR enabled, because the HSTCP mechanism is typically not triggered until you reach beyond 100 Mbps of WAN throughput.

Enabling Connection Pooling

You configure connection pooling in the Optimization Service - Connection Pooling page.

Connection pooling enhances network performance by reusing active connections instead of creating a new connection for every request. A connection pool manager maintains a pool of open connections. When a new connection request comes in, the pool manager checks if the pool contains unused connections and returns one if available. If all connections currently in the pool are busy and the maximum pool size has not been reached, the new connection is created and added to the pool. When the pool reaches its maximum size all new connection requests are queued up until a connection in the pool becomes available or the connection attempt times out.

Connection pooling is useful for protocols which open a large number of short lived connections, such as HTTP.

Enabling this feature is optional.

Speed and Duplex Tips

5. Click Save to save your settings permanently or click Reset to return the settings

You modify the settings for the in-path interface in the Host Settings - Interface: InPath (LAN/WAN) page.

You specify the in-path interface if you plan to have the appliance in the direct path (the same subnet) as the client and the server in your network. You also set the in-path gateway (WAN router).

NOTE: You were prompted to configure the in-path interface when you completed the installation wizard. This section describes how you can modify these settings.

If your network routers do not automatically negotiate the speed and duplex, you must manually set the speed and duplex for the in-path interface (that is, the HP EFS WAN Accelerator).

Speed and duplex mismatches can easily occur in a network. For example, if one end of the link is set at half or full-duplex and the other end of the link is configured to auto negotiate (auto), the link defaults to half-duplex, regardless of the duplex setting on the non-auto-negotiated end. This duplex mismatch passes traffic, but it causes interface errors and results in degraded optimization.

The following are general guidelines to avoid speed and duplex mismatches when configuring the HP EFS WAN Accelerator:

54 CONFIGURING THE HP EFS WAN ACCELERATOR

 Routers are often configured with fixed speed and duplex settings. Check your

router configuration and set it to match the HP EFS WAN Accelerator WAN and LAN settings. Make sure your switch has the correct setting.

 After you finish configuring the HP EFS WAN Accelerator, check for speed and

duplex error messages (crc or frame errors) in the Logging, View System Log page of the Management Console. For detailed information about viewing HP EFS WAN Accelerator logs, see “Viewing HP EFS WAN Accelerator Logs” on

page 201.

 If there is a serious problem with the HP EFS WAN Accelerator and it goes into

bypass mode (that is, it automatically continues to pass traffic through your network), a speed and duplex mismatch might occur when you reboot the HP EFS WAN Accelerator. To avoid a speed and duplex mismatch, configure your LAN external pair to match the WAN external pair. For example, auto on the LAN and WAN and fixed to 100 FULL on the LAN and WAN.

Enabling Asymmetric Routing AutoDetection

You enable asymmetric route auto-detection in the Advanced Networking Asymmetric Routing page. Asymmetric route auto-detection detects and reports asymmetric routing conditions and caches this information to avoid losing connectivity between a client and a server.

When HP EFS WAN Accelerators are deployed in a network, all TCP traffic must flow through the same HP EFS WAN Accelerators in the forward and reverse direction. If traffic flows through an HP EFS WAN Accelerator in one direction and not the other, then TCP clients are unable to make connections to TCP servers. When deploying HP EFS WAN Accelerators into redundant networks, there is a possibility of traffic taking different forward and return paths so that traffic in one direction goes through HP EFS WAN Accelerators but traffic in the reverse direction does not.

If asymmetric routing is detected, the pair of IP addresses, defined by the client and server addresses of this connection, is cached on the HP EFS WAN Accelerator. Further connections between these hosts are not optimized until that particular asymmetric routing cache entry times out.

Detecting and caching asymmetric routes does not optimize these packets. If you want to optimize asymmetric routed packets you must make sure that packets going to the WAN always go through an HP EFS WAN Accelerator either by using a multi-port HP EFS WAN Accelerator, connection forwarding, or using external ways to redirect packets, such as WCCP or PBR.

For detailed information, see “Enabling Connection Forwarding” on page 68 or the HP StorageWorks Enterprise File Services WAN Accelerator Deployment Guide.

Enabling Connection Forwarding

You enable connection forwarding in a network configuration with multiple paths from the server in the Advanced Networking - Connection Forwarding page.

You enable connection forwarding only in asymmetric networks; that is, in networks in which a client request traverses a different network path than the server response.The default port for connection forwarding is 7850.

To optimize connections in asymmetric networks, packets traveling in both directions must pass through the same client-side and server-side HP EFS WAN Accelerator. If you have one path from the client to the server and a different path from the server to the client, you need to enable in-path connection forwarding and configure the HP EFS WAN Accelerators communicate with each other. These HP EFS WAN Accelerators are called neighbors and exchange connection information to redirect packets to each other.

Figure 2-25. Asymmetric Network

Neighbors can be placed in the same physical site or in different sites but the latency between them should be small because the packets travelling between them are not optimized.

IMPORTANT: When you define a neighbor, you specify the HP EFS WAN Accelerator in-path IP address, not the primary IP address.

If there are more than two possible paths, additional HP EFS WAN Accelerators must be installed on each path and configured as neighbors. Neighbors are notified in parallel so that the delay introduced at connection set up is equal to the time it takes to get an acknowledgement from the furthest neighbor.

For detailed information about connection forwarding, see the HP StorageWorks Enterprise File Services WAN Accelerator Deployment Guide.

Enabling Encryption

You configure IP Security Protocol (IPsec) encryption to allow data to be communicated securely between peer HP EFS WAN Accelerators in the Advanced Networking - Encryption page.

Enabling IPsec encryption makes it difficult for a third party to view your data or pose as a machine you expect to receive data from. To enable IPsec, you must specify at least one encryption and authentication algorithm. Only optimized data is protected, pass-through traffic is not.

Enabling IPsec support is optional.

IMPORTANT: You must set IPsec support on each peer HP EFS WAN Accelerator in your network for which you want to establish a secure connection. You must also specify a shared secret on each peer HP EFS WAN Accelerator.

NOTE: If you Network Address Translate (NAT) traffic between HP EFS WAN Accelerators, you cannot use the IPSEC channel between the appliances because the NAT changes the packet headers causing IPSEC to reject them.

Enabling Failover and Data Store Synchronization

You enable failover and automatic data store synchronization support in the Advanced Networking - Failover Settings page.

Failover support ensures continued optimization if there is a failure with one of the HP EFS WAN Accelerators. If the master HP EFS WAN Accelerator fails, the traffic is automatically processed by the backup HP EFS WAN Accelerator.

Automatic data store synchronization replicates the data store from an active HP EFS WAN Accelerator to a passive HP EFS WAN Accelerator without disrupting operations. Data store synchronization ensures that a warm data store exists on the backup HP EFS WAN Accelerator. With a warm data store, the backup HP EFS WAN Accelerator can perform as optimally as its master when it is activated; that is, it performs as if it has seen the data before and only sends new segments across the WAN.

NOTE: Data is replicated only from the master HP EFS WAN Accelerator to the backup; not vice versa.

NOTE: All operations occur in the background and do not disrupt operations on any of the systems.

Automated Online Datastore Settings

Enable Automated Online Datastore Synchronization. Specify this option to enable automated data store synchronization. Data store synchronization ensures that each data store in your network has warm data for maximum optimization. All operations occur in the background and do not disrupt operations on any of the systems.

There are the following phases in synchronization:

• Catchup. Copies data that is already on the master to the backup HP EFS WAN Accelerator. This process stops when all the old data from the master is copied to the backup HP EFS WAN Accelerator.

• Keepup. Runs continuously copying new data that the master appliance encounters to the backup HP EFS WAN Accelerator.

IMPORTANT: The HP EFS WAN Accelerators must be the same model; models running different versions of the software will not synchronize (for example v2.x to 3.x). Synchronization does not guarantee that all data objects are replicated—synchronization runs in the background, if the HP EFS WAN Accelerator is under load, all data may not be replicated.

NOTE: If you are setting up automated data store synchronization for the first time, the HP EFS WAN Accelerator service is halted on the backup HP EFS WAN Accelerator. You must restart the HP EFS WAN Accelerator service on backup HP EFS WAN Accelerators. If you restart the service with a clean data store you must shutdown the backup HP EFS WAN Accelerator, power it off, and power it on.

NOTE: In out-of-path configurations, you must designate an HP EFS WAN Accelerator as a backup appliance, either by enabling failover support or by designating it as an outof-path backup appliance, to implement data store synchronization.

Current Appliance is the. Select Master or Backup from the drop-down list. You must specify the primary IP address for the master and backup appliance.

Enabling Peering Rules for Serial Clustering

You can configure peering rules that apply to a single port or you can configure peering rules that apply to a port label. A port label is a label that you assign to a set of ports so that you can reduce the number of configuration rules in your system. For detailed information about how to configure port labels, see “Creating Port Labels” on

page 113.

You can provide increased optimization by deploying several HP EFS WAN Accelerators back-to-back in an in-path configuration to create a serial cluster. For detailed information, see the HP StorageWorks Enterprise File Services WAN Accelerator Deployment Guide.

Appliances in a cluster process the peering rules you specify in a spill-over fashion. When the maximum number of TCP connections for an HP EFS WAN Accelerator is reached, that appliance stops intercepting new connections and passes them on to the next HP EFS WAN Accelerator in the cluster (as defined by the peer rule that you set).

In serial cluster deployments:

 The peering rules table is a ordered list of rules and the first rule that matches the

rule is applied.

 To avoid interceptions on inner connections created by other appliances in the

same cluster, in-path rules are specified to pass-through connections originating from those appliances.

You can configure QoS on HP EFS WAN Accelerators to control the prioritization of different types of network traffic and to ensure that HP EFS WAN Accelerators give certain network traffic (for instance, voice over IP) higher priority than other network traffic.

HP STORAGEWORKS EFS WAN ACCELERATOR MANAGEMENT CONSOLE USER GUIDE 81

QoS allows you to specify priorities for various classes of traffic and properly distributes excess bandwidth among classes. The HP EFS WAN Accelerator allows you to decouple priority (in terms of delay) from the bandwidth allocation. This provides the flexibility needed to support varying degrees of priority and bandwidth traffic patterns, such as high-priority, low-bandwidth traffic patterns (for example, Telnet). Many QoS schemes use the term priority to specify how to control the excessive bandwidth among different classes. In the HP EFS WAN Accelerator, priority actually refers to traffic delays and excessive bandwidth is shared, proportional to the minimum bandwidth guaranteed for a specific class.

Enabling this feature is optional.

Setting QoS Marking

7. Click Save to save your settings permanently or click Reset to return the settings

to their previous values.

You set QoS marking in the Advanced Networking - QoS Marking page.

The QoS feature allows you to enforce a DSCP level for optimized connections. The DSCP level corresponds to the DiffServ DSCP field in the IP packets header. After you map a source-destination-port pattern and a DSCP level, every packet corresponding to the connection with that destination port has the DSCP field set to that value in the forward and backward direction. On the WAN side of the HP EFS WAN Accelerator, you configure a network router or a traffic shaper to prioritize packets according to the value in the DSCP field before they are sent across the WAN.

After you map a destination port and a DSCP level, every packet corresponding to the connection with that destination port has the DSCP field set to that value in the forward and backward direction. On the WAN side of the HP EFS WAN Accelerator, you configure a network router or a traffic shaper to prioritize packets according to the value in the DSCP field before they are sent across the WAN.

Note that only the first matching mapping will be applied.

Enabling this feature is optional.

Enabling Simplified Routing

You can enable simplified routing in the Advanced Networking - Simplified Routing page.

Simplified routing collects the IP address for the next hop Media Access Control (MAC) address from each packet it receives to use in addressing traffic. Enabling simplified routing eliminates the need to add static routes when the HP EFS WAN Accelerator is in a different subnet from the client and server.

Without simplified routing if an HP EFS WAN Accelerator is installed in a different subnet from the client or server, you must define one router as the default gateway and static routes for the other routers so that traffic is not redirected back through the HP EFS WAN Accelerator. In some cases, even with the static routes defined, the Access Control List (ACL) on the default gateway may still drop traffic that should have gone through the other router.

Simplified routing has the following constraints:

 Broadcast support in Proxy File Service configurations cannot be enabled.

 WCCP cannot be enabled.

 Connection forwarding cannot be enabled if you collect mappings for source

MAC data (that is, the options all or dest-source).

 The default route must exist on each HP EFS WAN Accelerator in your network.

 Simplified routing requires a client-side and server-side HP EFS WAN

Accelerator.

Enabling WCCP Groups

You can enable WCCP service groups in the Advanced Networking - WCCP Service Groups page.

WCCP enables you to redirect traffic that is not in the direct physical path between the client and the server. To enable WCCP, the HP EFS WAN Accelerator must join a service group at the router. A service group is a group of routers and HP EFS WAN Accelerators which define the traffic to redirect, and the routers and HP EFS WAN Accelerators the traffic goes through.

Enabling WCCP is optional.

TIP: You can also use the HP EFS WAN Accelerator Command Line Interface (CLI) to configure WCCP service groups. For detailed configuration information (including configuring the WCCP router), see the HP StorageWorks Enterprise File Services WAN Accelerator Deployment Guide.

NOTE: The following section assumes you are familiar with WCCP. For detailed information about WCCP, see the Cisco documentation Web site at http://www.cisco.com/univercd/home/home.htm.

HP STORAGEWORKS EFS WAN ACCELERATOR MANAGEMENT CONSOLE USER GUIDE 95

Control Description

Add New Service Group Service Group ID. Specify the service group identification number (from 0 to 255).

The service group ID is the number that is set on the router. A value of 0 specifies the standard http service group.

Router IP. Specify a multicast group IP address or a unicast router IP address. You can specify up to 32 routers. For information on adding additional routers to the group, see

“Modifying WCCP Group Settings” on page 96.

Password/Confirm Password. Optionally, you can assign a password to the HP EFS WAN Accelerator. This password must be the same password that is on the router. WCCP requires that all routers in a service group have the same password. Passwords are limited to 8 characters.

Priority. Specify the WCCP priority for traffic redirection. If a connection matches multiple service groups on a router, the router chooses the service group with the highest priority. The range is 0-255. The default value is 200.

Wei ght. Determine how often the traffic is redirected to a particular HP EFS WAN Accelerator. A higher weight redirects more traffic to that HP EFS WAN Accelerator. The ratio of traffic redirected to an HP EFS WAN Accelerator is equal to its weight divided by the sum of the weights of all the HP EFS WAN Accelerators in the same service group. For example, if there are two HP EFS WAN Accelerators in a service group and one has a weight of 100 and the other has a weight of 200, the one with the weight 100 receives 1/3 of the traffic and the other receives 2/3 of the traffic. The range is 0-65535. The default value corresponds to the number of TCP connections your appliance supports.

NOTE: To enable failover support for WCCP groups, define the service group weight to be 0 on the backup HP EFS WAN Accelerator. If one HP EFS WAN Accelerator has a weight 0, but another one has a non-zero weight, the HP EFS WAN Accelerator with weight 0 does not receive any redirected traffic. If all the HP EFS WAN Accelerators have a weight 0, the traffic is redirected equally among them.

Modifying WCCP Group Settings

WAN A

CCELERATOR

Enabling PFS You can enable and configure PFS support in the Proxy File Service (PFS) -

Configuration page.

NOTE: PFS is not supported on the Model 510.

PFS is an optional integrated virtual file server that allows you to store copies of files on the HP EFS WAN Accelerator with Windows file access, while creating several options for transmitting data between remote offices and centralized locations with improved performance and functions. PFS provides:

 LAN access to data residing across the WAN.

 Continuous access to files in the event of WAN disruption.

 Simplified branch infrastructure and backup architectures.

In v3.0 you no longer need to install the HP EFS Remote Copy Utility (RCU) service on the server to synchronize your PFS shares—all RCU functionality has been moved to the HP EFS WAN Accelerator. When you upgrade from v2.x to v3.x all your existing shares will be running as v2.x shares. If you have legacy shares (that is, shares created with Version v2.x software), you can convert your v2.x shares to v3.x shares in the Management Console.

For detailed information about PFS and when to enable it, see the HP StorageWorks Enterprise File Services WAN Accelerator Deployment Guide.

Enabling PFS support is optional.
