24 Introduction
System Components
The PowerVault NX3500 system consists of:
• Hardware
– NAS controller pair
– MD PowerVault storage
– Backup power supply
•Network
– SAN network
– Internal network
– LAN or client network
NAS Controller Pair
The PowerVault NX3500 clustered NAS solution consists of two NAS
controllers configured as a pair. This redundant configuration ensures that
there is no single point of failure. The controllers handle load balancing of
client connections, manage read-write operations, perform caching, and
interface with servers and workstations. The cluster and its internal networks
are consolidated using a virtual IP.
The PowerVault NX3500 software is installed on both controllers. The
software is a complete package, consisting of an operating system, volume
management, distributed file system, and clustering technology.
Read-write operations are handled through mirrored non-volatile RAM
(NVRAM). Mirroring the cache data between the paired NAS controllers,
ensures a quick response to clients' requests, while maintaining complete data
integrity. Data from the cache to permanent storage is transferred
asynchronously through optimized data-placement schemes.
Each controller is equipped with a 12 GB RAM, most of which is used for
caching. The file system uses the cache efficiently to provide fast and reliable
writes and reads. Writing or modifying files occurs first in the cache. Data is
then mirrored to the peer controller’s cache. This feature ensures that all
transactions are duplicated and secured.
Introduction 25
PowerVault MD Storage
The controllers connect to the PowerVault MD iSCSI storage array, which is a
RAID subsystem. RAID storage subsystems are designed to eliminate single
points of failure. Each active component in the storage subsystem is
redundant and hot-swappable. The solution supports typical RAID
configurations including RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10.
BPS
The BPS provides continuous power to the controllers. Each controller
receives its power from a dedicated BPS and from the power grid. The
controllers regularly monitor the BPS battery status, which requires the BPS
to maintain a minimum level of power for normal operation. The BPS has
sufficient battery power to allow the controllers to safely shut down.
The BPS enables the controllers to use the cache as NVRAM. The BPS
provides the clustered solution enough time to write all the data from the
cache to the disk if the controller experiences a loss of power.
NOTE: You can view the BPS events on the NAS Manager.
SAN Network
The SAN network is a critical part of the PowerVault NX3500 solution. The
controller pair that resides on the SAN network communicates to the storage
subsystem using the iSCSI protocol. The PowerVault NX3500 communicates
on the SANa and SANb networks, rendering a high availability (HA) design.
Internal Network
The PowerVault NX3500 solution requires an internal network for peer-topeer data transfer and management. To achieve complete data distribution
and to maintain HA, each controller must have access to its peer controller.
The internal network achieves this goal.
The internal network is classified into internal network A and internal network B.
NOTE: Ensure that the IP addresses you assign to internal network A and internal
network B are from a private IP space and do not conflict with other subnets on
your network.
26 Introduction
Internal Network A
PowerVault NX3500's internal network A is comprised of two independent
Gigabit Ethernet ports. The internal network is the infrastructure for the
PowerVault NX3500 clustering, and includes heartbeat monitoring, data
transfer, and mirroring of information between the controllers' caches. The
internal network also distributes data evenly across all LUNs in the system.
NOTE: Internal network A is also referred to as peer-to-peer connections. The
network uses point-to-point cable connections.
Internal Network B
Internal network B is the PowerVault NX3500 internal management network,
which is plugged into the SAN switch and connects both controllers. All
administrative related functions are performed on this network.
In the event where the controllers lose communication with each other but
continue to function independently (known as the split-brain situation), the
PowerVault management network automatically resets the suspected
controller. This prevents the split-brain situation and ensures data integrity.
LAN or Client Network
After the initial configuration, a virtual IP (VIP) address connects the
PowerVault NX3500 to the client or LAN network.
The VIP address allows clients to access the PowerVault NX3500 as a single
entity, thereby providing access to the file system. It enables the PowerVault
NX3500 to perform load balancing between controllers, and ensures that the
service continues even if a controller fails.
The LAN or client network is comprised of two Gigabit Ethernet ports on
each controller, which connect to the LAN or client network switches. The
solution can have a maximum of four VIPs that serve the system. For more
information, see “Setting Up Your PowerVault NX3500 Solution” on page 29.
The PowerVault NX3500 solution is administered using the LAN or client
network on the NAS Management VIP.

The following settings are highly recommended on your switch:
• Spanning Tree Portfast (required)
• Flow control (required)
• Jumbo frames (9000 MTU)
NOTE: Dell PowerConnect switches need to be configured to 9216 MTU or greater
to accept frames of size 9000 MTU. Non-Dell switches may require a different MTU
configuration for similar frame sizes. For more information on MTU configuration for
non-Dell switches, see the switch-specific manual.
NOTE: Jumbo frames and flow control settings are mandatory for all ports used
solely by the PowerVault NX3500 and file access, for block usage port setting,
please refer to your array user guide for optimal performance setting.

Figure 2-3. NX3500 Node NIC Cabling
NOTE: See Figure 2-3 to connect the PowerVault NX3500 and MD ports to the
appropriate switch in the for the best practice solution in the HA option.
Best Practice Solution in the HA Option
The best practice solution is to isolate the SAN traffic from the LAN or client
traffic with redundant switches for HA. All the client cables are split between
the redundant client switches, and the SAN or internal network cables are
split between the redundant SAN switches. Peer connections are always back
to back.
NOTE: For cabling recommendation for existing MD-Series implementations that
do not have stacked switches, see “Cabling Recommendation” on page 213.
NOTE: The PowerVault NX3500 solution expects only two subnets (iSCSI ports) per
MD controller to be used by the solution. The other four ports are dedicated to
block devices.

The second configuration option is to isolate the SAN traffic from the client
traffic, but without redundant switches. All the client cables are connected to
the client switch and the SAN or internal network cables are connected to the
SAN switch. Peer connections are always back to back.
In this configuration, the switches become a single point of failure. It is
recommended that you separate the SAN subnets using virtual LANs.

Running the PowerVault NASCU
The PowerVault NAS Configuration Utility (NASCU) walks you through the
steps necessary to set up the network configuration and pair the PowerVault
NX3500 controllers together. It also starts the process of pairing the system to
the PowerVault MD3xx0i storage appliance. It is recommended that you
determine your network configuration and IP address allocation for your NAS
controllers before executing this utility. See “Completing the NAS System
Setup Worksheet” on page 42.
Before running the PowerVault NASCU, ensure that:
• The PowerVault NASCU is installed and executed from a management
station that has IPv6 enabled. The utility connects to and configures your
controllers through the local link Ipv6 address. Ipv6 can be disabled, but
only after the installation and configuration is complete.
• The management station is connected to the same switch as the client
connections on your NAS controllers (see Table 2-1).
NOTE: Use the PowerVault NASCU only for initial configuration. After the PowerVault
NX3500 is configured use the NAS Manager to make changes to the configuration.
Installing the PowerVault NASCU
NOTE: Do not attempt to use the PowerVault NASCU to reconfigure an already
clustered PowerVault NX3500 solution.

The client connections table provides the following information.
Table 4-8. Client Connections Page
Field Description
Client/router IP The IP address of the client or router accessing the system.
Access using IP The IP address used to access the system.
Assigned interface The controller and network interface which were allocated for
this client or router (either automatically by the system or
manually by an administrator).
Current interface The controller and network interface currently assigned to
this client or router. The current interface can be different
from the assigned interface after automatic connection failover. Depending on the Migration Policy, a connection that
was migrated from its assigned controller to another
controller, can remain on that controller. In such an event, the
current interface is different from the assigned interface.
Protocol The protocol that the client connection uses: CIFS, NFS, or
Other. PowerVault NX3500 identifies the clients accessing
with a recognized protocol, CIFS, or NFS and displays the
actual protocol. For other local clients, for example, routers,
the system displays the value 'Other' as the protocol.

Usage Considerations
Migrating Clients to Another Controller
If there is an imbalance in the network load, the system can rebalance the
load by migrating clients between controllers, either automatically or
manually. Choose whether the clients or routers in the list may be migrated to
other controllers.
Select the connections you want to migrate from the list and click Assign
Interface. The Assign Interface page displays, and lists the selected
connections for approval.
Choose the controller you want to migrate the selected clients to. You can
either choose a specific controller as the target or choose Assigned Controller.
• To migrate all the selected clients to a specific controller, choose a specific
controller from the list.
• To migrate all the selected clients back to their original controllers after a
failed controller is revived, choose the Assigned Controller. Each client can
have a different assigned controller.
You can either let the system select the target interface on the controller, or
choose a specific one.
NOTE: This operation will disconnect CIFS connections if they are migrated to a
different controller.
• To enable automatic rebalance, select
other controllers when rebalancing the network load
• To keep the selected clients assigned controller permanent (except during
fail-over) clear

Setting the Migration Policy
In case of a controller failure, the system automatically migrates each
connection from the failed controller to another controller to allow clients to
continue their work. This causes disconnections to CIFS clients. When the
failed controller revives, the system can rebalance the load by migrating
clients back to the revived controller automatically. This operation is called
fail-back.
Monitoring PowerVault NX3500 81
Clients that use NFS are stateless and are not affected during fail-back.
Clients that use connection-based protocols (CIFS), may be disconnected
during fail-back. To optimize the fail-back operation, the system provides you
with the following policies for migration on recovery, which affect the loadbalance and disconnections:
• Migrate Immediately—Always keep the system well balanced, at the cost
of possibly disconnecting CIFS clients during work time.
• Migrate Automatically— Always keep the system well balanced if the
controller failure is very short, at the cost of disconnecting CIFS clients.
This option causes the system to remain unbalanced for a period of several
days, if the failure remains for long time.
This mode overcomes short controller failures because clients have not
created new material during the short time failure. Therefore, the best
practice is to rebalance them as soon as possible.
If the failure is longer than 10 minutes, the system remains unbalanced
until you rebalance it manually.
• Migrate Manually— Never migrates clients automatically. This requires
manual intervention to rebalance the system.
If the system requires manual intervention to rebalance it after fail-over,
the system sends an appropriate email message to the administrator.
You can configure the fail-back policy, as described above, per protocol and
LAN or client network.

NAS Volumes
A NAS volume is a subset of the storage pool, with specific policies
controlling its space allocation, data protection, and security style.
NAS volumes can be created and configured. Administrators can either create
one large NAS volume consuming the entire NAS Pool or multiple NAS
volumes. In either case you can create, resize, or delete these NAS volumes.
This section describes how an administrator allocates and deploys NX3500
storage using NAS volumes. In order to make NAS volumes available to users,
they must be shared (exported) separately. Users need to specifically mount
each share.

92 Using Volumes, Shares, and Quotas
Usage Considerations
Choosing to define multiple NAS volumes enables administrators to apply
different management policies such as, Backup, Snapshots, Quotas, and
Security Style to their data. Without regard to the strategy used, the storage is
managed as one storage pool and free space can easily be migrated between
NAS volumes, by changing the NAS volume's allocated space.
Consider the following factors before choosing a strategy:
• General requirements
– NAS volumes are logical; they can be easily created, deleted or
modified (increased or decreased) based on the system capacity.
– The NAS volume name should not contain more than 230 characters.
It should contain only letters, digits and underscores (_) and should
begin with either a letter or an underscore.
– You can create as many virtual volumes as you want, but the total
capacity cannot exceed the total storage capacity.
– A single volume can occupy data of various types, by defining multiple
shares on the volumes.
– You can resize a virtual volume after creating it.
– The minimum size of a NAS volume is 20MB (or if the volume has
already been used, the minimum size is the stored data).
– The maximum size of a NAS volume is the remaining unallocated space.
• Business requirements—A company or application requirement for
separation or for using a single volume should be considered. NAS volumes
can be used to allocate storage for departments on demand, using the
threshold mechanism to notify departments when they approach the end
of their allocated free space.
• Snapshots—Each NAS volume can have a dedicated snapshot scheduling
policy to best protect the type of data it stores.
• Security style—In multiple protocol environments, it may be beneficial to
separate the data and define NAS volumes with UNIX security style for
UNIX-based clients, and NTFS for Windows-based clients. This enables
the administrator to match the security style with business requirements
and various data access patterns.
Using Volumes, Shares, and Quotas 93
• Quotas—Quotas are also defined per NAS volume. Different quota
policies can be applied to different NAS volumes, allowing the
administrator to focus on managing quotas when it is appropriate.
Some of the usage examples are copy operations, list operations, and move
operations. Table 6-2 provides an example of an organization that has various
departments and how NAS volumes can be created. The right solution
depends on the customer’s requirements because NAS volumes are flexible
and they can be expanded and reduced on demand.

Solution 1
Create five NAS volumes based on the departments. The administrator
logically breaks up the storage and the management into functional groups.
In this scenario, the departmental requirements are quite different and
supports the design to logically create NAS volumes along department lines.
94 Using Volumes, Shares, and Quotas
This solution provides the following advantages:
• It is logically easy to manage the NAS volumes.
• The NAS volumes are created to match the exact needs of the department.
The disadvantage of this option is that the NAS volumes become difficult to
manage if the number of departments in the organization increases.
Solution 2
Group departments that have similar security requirements into NAS
volumes. The administrator creates three NAS volumes, one for NFS, one for
CIFS, and another for mixed. The advantage is that the NAS volumes work
separately between Windows and Linux. This solution has the following
disadvantages:
• All files in a NAS volume are backed up.
• Unwanted services may be provided to certain departments. If a CIFS
volume is created to backup data for the administration and finance
departments, the press and legal departments will also get backups even
though they do not require it.
Solution 3
NAS volumes can also be created based on the feature. The disadvantage of
this solution is that user mapping is required. A user needs to choose one
security style, either NTFS or UNIX, and based on the security style chosen
the correct mapping for other users is set.

NOTE: The above parameters are the recommended parameters. It is
possible to change the protocol from tcp to udp, and the NFS version from 3 to 2.
To allow a UDP connection, you can configure the firewall settings in two
primary ways:
• Adjust the firewall settings so that the source IP address comes from either
of the two controllers and not the client VIP.
• Open the port range for UDP to allow ports as follows:
Service Name FluidFS Port
portmap 111
Statd 4000 through 4008
Nfs 2049 through 2057
nlm (lock manager) 4050 through 4058
mount 5001 through 5009

Setting Access Control Lists and Share Level Permissions on FluidFS
This section provides information about setting up access control lists
(ACLs) and share level permissions (SLP) on Fluid File System (FluidFS). It
is recommended that a Windows administrator follow the best practices as
defined by Microsoft.
Both ACLs and SLPs are supported by FluidFS. However, SLPs are limited as
they only address full control, modify and read rights for any given user or group.
CIFS Storage Administrator Account
A built-in local CIFS storage administrator account serves the primary
purpose of setting ownership of the CIFS share. The account can also be used
to set ACLs when the NAS service is not joined to an Active Directory
domain. This built-in account has a randomly generated password for security
purposes. You must change this password before attempting to set any ACLs
or SLPs.
Active Directory Configuration
FluidFS has the ability to join an Active Directory domain. This can be done
using the NAS Manager or the CLI. For more information, see "Configuring
the Active Directory Service" on page 133.
Setting ACLs or SLPs on a CIFS Share
The first time a CIFS share is created, the owner of the share must be
changed prior to setting any ACLs or attempting to access this share. If the
PowerVault NX3500 is joined to an Active Directory domain, the following
methods can be used for setting ACLs:
• Using an Active Directory domain account that has its primary group set as
the Domain Admins group.
