Table 2 Storage Manager Hardware Requirements

File Systems RAM Disk Space

1–4* 2 GB • For application binaries, log files,

5–8** 4 GB

and documentation: up to 30GB (depending on system activity)

• For support directories: 3 GB per million files stored

†

• For metadata: 25GB minimum

* Two CPUs recommended for best performance. ** Two CPUs required for best performance.

†

For non-managed file systems, the requirement is 1GB per million files stored.

Note: If a file system uses deduplicated storage disks (DDisks), note

the following additional requirements:

• Requires 2 GB RAM per DDisk in addition to the base RAM noted in

Table 2.

• Requires an additional 5GB of disk space for application binaries and log files.

• Deduplication is supported only for file systems running on a Linux operating system.

• An Intel Pentium 4 or later processor (or an equivalent AMD processor) is required. For best performance, Quantum recommends an extra CPU per blockpool.

Partitioning Local Hard Disks 1

StorNext can be installed on any local file system (including the root file system) on the MDC. However, for optimal performance, as well as to aid disaster recovery, follow these recommendations:

• Avoid installing StorNext on the root file system.

• Partition local hard disks so that the MDC has four available local file systems (other than the root file system) located on four separate hard drives.

StorNext 3.5 Installation Guide 3

Chapter 1 Installing StorNext File System and Storage Manager

Storage Manager System Requirements

Note: You can run the pre-installation script to help determine the

estimated size of and optimal location for StorNext support directories. For more information, see

Pre-Installation Script

on page 8.

LAN Requirements 1

The following LAN requirements must be met before installing StorNext on the MDC:

• In cases where gigabit networking hardware is used and maximum StorNext performance is required, a separate, dedicated switched Ethernet LAN is recommended for the StorNext metadata network. If maximum StorNext performance is not required, shared gigabit networking is acceptable.

• A separate, dedicated switched Ethernet LAN is mandatory for the metadata network if 100 Mbit/s or slower networking hardware is used.

• The MDC and all clients must have static IP addresses.

Verify network connectivity with pings, and also verify entries in the

/etc/hosts file. Alternatively, telnet or ssh between machines to verify

connectivity.

• If using Gigabit Ethernet, disable jumbo frames and TOE (TCP offload engine).

Note: StorNext does not support file system metadata on the same

network as iSCSI, NFS, CIFS, or VLAN data when 100 Mbit/s or slower networking hardware is used.

StorNext 3.5 Installation Guide 4

Getting Ready to Install

Before installing StorNext SNFS and SNSM, complete the following tasks to ensure successful installation:

• Correctly configure all storage devices (see Configuring Storage

Devices).

• If using LUNs larger than 1 TB, decide on a label type and install any necessary operating system patches (see

than 1 TB).

• (Linux only) Install the kernel source code (see Installing the Linux

Kernel Source Code on page 7).

Chapter 1 Installing StorNext File System and Storage Manager

Getting Ready to Install

Planning for LUNs Larger

Configuring Storage Devices 1

Planning for LUNs Larger than 1 TB 1

Before installing StorNext SNFS and SNSM, make sure that all LUNs are visible to the MDC. (A LUN, or logical unit number, is a logical device that corresponds to one or more disks, drives, or storage devices.)

If there are any connection issues, resolve them before installing StorNext. For assistance in configuring storage devices, refer to the documentation that came with the storage device, or contact the manufacturer.

Note: LUNs that you plan to use in the same stripe group must be

the same size. Consider this when configuring storage devices. (For more information about stripe groups, see the StorNext 3.5 User’s Guide.)

Caution: StorNext does not support the connection of multiple

devices through fibre channel hubs. Multiple devices must be connected using fibre channel switches.

of the operating system running on the MDC as well as the operating system running on all connected clients. Disk LUNs can have one of three labels: VTOC, EFI, or sVTOC (short VTOC).

Required disk LUN label settings based on operating system and LUN size are presented in

Table 3. Before installing StorNext, decide what

label type will be used, and then install any required operating system patches or updates (for both MDC and client) as indicated in the notes for

Table 3.

Note: After labeling a disk LUN, you must reboot systems running

Solaris before they can access the disk LUN.

Note: For best results, Quantum recommends using persistent

binding for disk LUNs. For more information, contact the vendor of your HBA (host bus adapter).

For management servers running Red Hat Enterprise Linux version 4 or 5, before installing SNFS and SNSM you must first install the kernel header files (shipped as the kernel-devel or kernel-devel-smp RPM, depending on your Linux distribution).

For servers running SUSE Linux Enterprise Server, you must install the first kernel source code (shipped as the kernel-source RPM). StorNext will not operate correctly if these packages are not installed. You can install the kernel header files or kernel source RPMs by using the installation disks for your operating system.

Verifying Hostname Length 1

The maximum hostname length for a StorNext server is limited to 25 characters. Before you begin the installation, verify that the destination hostname is not longer than 25 characters. (The hostname is read during the installation process, and if the hostname is longer than 25 characters the installation process could fail.)

StorNext 3.5 Installation Guide 7

Pre-Installation Script

The StorNext pre-installation script (snPreInstall) is included on the StorNext installation CD. When you run for information about your system. The pre-installation script uses this information to estimate the amount of local disk space required for SNFS and SNSM support directories. In addition, the script recommends the optimal locations for support directories.

StorNext uses five directories to store application support information. These directories are stored locally on the metadata controller, except for the

Backup directory, which is stored on the managed file system.

The StorNext support directories are described in Table 4.

Chapter 1 Installing StorNext File System and Storage Manager

Pre-Installation Script

Contains configuration files and support data required for disaster recovery.

Before running the pre-installation script, be prepared to answer the following questions:

• Is this an upgrade installation?

• What local file systems can be used to store support information?

• Which version of StorNext will be installed?

StorNext 3.5 Installation Guide 8

Chapter 1 Installing StorNext File System and Storage Manager

Pre-Installation Script

• What is the maximum number of directories expected (in millions)?

• What is the maximum number of files expected (in millions)?

• How many copies will be stored for each file?

• How many versions will be retained for each file?

Note: Keep in mind that storage needs typically grow rapidly.

Consider increasing the maximum number of expected directories and files by a factor of 2.5x to ensure room for future growth.

Note: The pre-installation script ignores unmounted file systems.

Before running

snPreInstall, be sure to mount all local file

systems that will hold StorNext support information.

Running snPreInstall 1

To run the pre-installation script, use the StorNext installation CD.

1 Log on to the MDC as root. 2 Mount the StorNext installation CD and change to the CD root

directory.

3 List the installation directories on the CD. At the command prompt,

type:

ls -l

4 Identify the correct installation directory for your operating system

and hardware platform, and then change to that directory.

For example, for Red Hat Linux 5 running on an x86 64-bit platform, change to the

RedHat50AS_26x86_64 directory.

5 Run the script. At the command prompt, type:

./snPreInstall

The pre-installation script runs (figure 1).

Pre-Installation Script

6 Follow the onscreen instructions, and answer each question when

prompted.

The script outputs results based on the information you entered.

Interpreting snPreInstall Output 1

After you enter all requested information, the pre-installation script outputs the following results:

• Estimated disk space required for each support directory.

• Recommended file system location for each support directory.

Tech Tip: For optimal performance, each support directory

(other than the

Backup directory) should be located on

its own local file system, and each local file system should reside on a separate physical hard disk in the MDC.

There are three types of directory recommendations, as indicated by the text preceding the recommendation. The three types of recommendations are described in

StorNext 3.5 Installation Guide 10

Table 5.

Chapter 1 Installing StorNext File System and Storage Manager

Pre-Installation Script

Table 5 Pre-Installation Script Recommendation Types

Type Description

RECOMMEND The suggested directory locations will result in

optimal system performance.

NOTE The suggested directory locations are valid but

system performance will not be optimal.

SPACE Additional hard disk space is required to store

the required support directories.

The pre-installation script bases directory location recommendations on the following criteria:

• To aid disaster recovery, the Database and Journal directories should

be located on different file systems.

• For optimal performance, the Metadata directory should not be

located on the same file system as (in order of priority) the

Database, or Mapping directory.

Journal,

Note: Do not change the location of support directories manually.

Instead, use the installation script to specify the location for support directories. For more information, see

Getting Ready to Install

Before installing StorNext SNFS, complete the following tasks to ensure successful installation:

StorNext 3.5 Installation Guide 20

Chapter 2 Installing StorNext File System

Getting Ready to Install

• Correctly configure all storage devices (see Configuring Storage

Devices on page 21).

• If using LUNs larger than 1 TB, decide on a label type and install any necessary operating system patches (see

Planning for LUNs Larger

than 1 TB on page 21).

• (Linux only) Install the kernel source code (see Installing the Linux

Kernel Source Code on page 23).

Configuring Storage Devices 2

Planning for LUNs Larger than 1 TB 2

Before installing StorNext SNFS, make sure that all LUNs are visible to the MDC. (A LUN, or logical unit number, is a logical device that corresponds to one or more disks, drives, or storage devices.)

Note: LUNs that you plan to use in the same stripe group must be

the same size. Consider this when configuring storage devices. (For more information about stripe groups, see the StorNext 3.5 User’s Guide.)

Caution: StorNext does not support the connection of multiple

devices through fibre channel hubs. Multiple devices must be connected using fibre channel switches.

StorNext supports LUNs greater than 1 TB in size if they are allowed by the operating system. To enable support for 1 TB or larger LUNs, all StorNext LUNs must be correctly labeled according to the requirements of the operating system running on the MDC as well as the operating system running on all connected clients. Disk LUNs can have one of three labels: VTOC, EFI, or sVTOC (short VTOC).

Required disk LUN label settings based on operating system and LUN size are presented in

Table 9. Before installing StorNext, decide what

label type will be used, and then install any required operating system

StorNext File System Client Buffer Cache 3

To install and run the StorNext client software, the client system must meet the following minimum hardware requirements.

For SAN (FC-attached) clients or for distributed LAN clients:

•1 GB RAM

• 500 MB available hard disk space

For SAN clients acting as a distributed LAN server:

•2 GB RAM

• 500 MB available hard disk space

Note: Distributed LAN servers may require additional RAM

depending on the number of file systems, distributed LAN clients, and NICs used. See

Distributed LAN Server Memory Tuning in the StorNext User’s Guide for Distributed LAN

Server memory tuning guidelines.

As of StorNext 3.0, multiple mounted file systems typically share a single buffer cache. A StorNext client buffer cache is created for each different

cachebufsize. By default, all file systems have the same cachebufsize of

64K, so they all share the same buffer cache.

Note: These settings do not apply to Apple Xsan clients, which do

not use the StorNext buffer cache.

The amount of memory consumed by default for each cachebufsize depends on the platform type and the amount of memory in the system.

Table 12 shows the default amount of memory consumed by cachebufsize.

To see information about the buffer cache after mounting file systems, use the memory used by the buffer cache at mount time, use the

cvdb(1) command with the -b option. To change the amount of

buffercachecap

parameter.

On Windows, the non-paged pool is used for buffer cache memory until it consumes up to 64 megabytes (32-bit systems) or 64 gigabytes (64-bit systems). Any additional buffer cache memory comes from the paged pool.

Downloading the StorNext Client Software

The StorNext client software can be downloaded from a metadata controller. (To download the client software, the client system must have network access to the MDC.)

Note: You can download the client software only from MDCs

running Linux or Unix.

1 On the client system, point a web browser to the URL (host name and

port number) of the MDC. For example,

Use one of the following web browsers to access the MDC (make sure pop-up blockers are turned off):

• Internet Explorer 6.0 or later (including 7.0)

• Mozilla Firefox 1.5 or later (including 2.0 or later)

Configuring a Distributed LAN Client Server

Traditional StorNext SAN clients access data disks using a high throughput, low-latency fibre channel connection. In addition, using the distributed LAN client and server feature, StorNext clients can access data disks over a network instead of directly accessing disks.

A StorNext client running on Linux or Windows can be configured as a distributed LAN client or a distributed LAN server. (This is a licensed feature.)

• Distributed LAN Server: A distributed LAN server has direct access to data disks (using fibre channel) and makes the shared storage pool available to distributed LAN clients over a network.

• Distributed LAN Client: A distributed LAN client does not have direct access to data disks and instead accesses the shared storage pool by connecting to a distributed LAN server over a network. (Distributed LAN clients have full StorNext client functionality.)

Chapter 4 Configuring StorNext

Note: A StorNext client configured as a distributed LAN server

requires a dedicated system. Do not run other applications or services on a system configured as a distributed LAN server.

To configure a Linux client as a distributed LAN client, see Configuring a

Distributed LAN Client on Linux. To configure a Linux client as a

distributed LAN server, see Configuring a Distributed LAN Server on

Linux.

Yes. Most changes do

not take affect until the system is restarted.

Mount Point 4

StorNext file systems can be mapped to a drive letter or to a folder. When mapping to a folder, the folder must be empty or non-existent, and must

exist within an NTFS file system (e.g., C:\Mount\MySnfs). Use the Mount Point tab (figure 37) to specify drive mappings. Table 15

describes the fields on the Mount Point tab.

Note: Make sure the host list is the same for all clients on the SAN.

An incorrect or incomplete host list may prevent the client from connecting to the file system.

Distributed LAN 4

The Distributed LAN tab is used to enable and configure StorNext Distributed LAN (DLAN) Clients and Servers for a file system. The Enable Client and Enable Server radio buttons determine whether the system is a Client or Server. Note that separate licensing is required for DLAN.

StorNext Distributed LAN Clients provide the same functionality as normal StorNext Clients but do not need to be connected directly to the SAN. They instead send I/O via the TCP/IP network to a Distributed LAN Server; a normal SAN client with DLAN Server Selected in its configuration. Metadata is sent over the TCP/IP network directly to the File System Metadata Controller (Server/MDC).

Distributed LAN Clients request the location of normal DLAN Servers via the Name Server.

• Distributed LAN Server: A distributed LAN server has direct access to data disks (using fibre channel) and makes the shared storage pool available to distributed LAN clients over a network.

Note: A StorNext client configured as a distributed LAN server

requires a dedicated system. Do not run other applications or services on a system configured as a distributed LAN server.

Use the Distributed LAN tab (figure 38) to configure a distributed LAN server or a distributed LAN client. Table 16 describes the fields on the

Distributed LAN tab.

When this box is checked, the file system can be mounted and accessed without all the disks being accessible in the file system stripe groups. In this mode, file metadata can be viewed and changed, but no data can be accessed.

The default is to not allow a file system to be mounted unless all disks are accessible.

I/O Retry Time Seconds

I/O Penalty TIme Seconds

When you choose Allow I/O Timouts, this option controls the I/O retry behavior. This parameter establishes the amount of time that may elapse during an I/O retry sequence.

An I/O retry sequence consists of the following:

• Retry an I/O request across all available paths that are currently present.

• Compare the current time to the Instantiation time of the I/O request, if at least <n> seconds have elapsed, return the I/O request in error, otherwise reset the paths used, and retry again.

This option controls the Multi-Path I/O penalty value, where <n> is expressed in seconds with a minimum value of 1 and a maximum value of 15.

This parameter establishes the amount of time

a Path_In_Error will be bypassed in favor of

an Operational Path during a Multi-Path selection sequence. If all paths are currently in the Path_In_Error state, the first available path will be selected, independent of the Path_In_Error state.

The default value is 5 seconds.

Fast Failover Detection

When this box is checked, the client uses a more aggressive approach to detecting if the FSM has failed. With this option on, the client monitors the FSM heartbeat. If no heartbeat is detected within three (3) seconds, a failover request is initiated.

This option is desirable for near realtime activities that cannot sustain more than 10 seconds of access loss to the server. Quantum does not recommend enabling this option for normal file system operations.

Hard Reconnect

Token Hold Seconds

When this box is checked, the file system attempts to reconnect to the FSM forever. If this option is not enabled, the file system attempts to reconnect to the FSM for the number of times specified at the Mount Retransmit Limit field before failing the request.

The default value is off.

The QOS Token Hold Time parameter is applicable only when using the StorNext Quality of Service (QOS) feature for real-time IO.

This parameter determines the number of seconds a client stripe group holds on to a non-realtime I/O token during periods of inactivity. If no I/O is performed on a stripe group within the specified number of seconds, the token is released back to the FSM.

The default value is 60 seconds. The parameter should be specified in five-second increments; if the parameter is not a multiple of five, it will be rounded up automatically.

Advanced Cache Options 4

The Data Buffer Cache keeps the file system data in memory on the local computer to speed up performance for small I/O operations.

The Advanced Cache Options tab (figure 40) displays performance values that control how many file system lookup names are kept in memory.

Caution: Changing the values on the Advanced Cache Options tab

can affect system performance and stability. Do not change cache parameters unless instructed to do so by the Quantum Technical Assistance Center.

Enable Data Buffer Cache

When this box is not checked, the file system will not buffer any data. All files will be read directly into the application's memory using DMA. Requests that are not properly aligned will be read into temporary buffers, then copied to the application's buffer.

If Buffer Cache is disabled, the remaining Data Buffer Cache options are ignored.

Individual Buffer Size

Minimum Total Cache Size

Auto-DMA Read/Write Sizes

This option sets the size of each cache buffer. This determines the I/O transfer size used for the buffer cache. For optimal performance, Individual Buffer Size should match the RAID stripe size. If Individual Buffer Size is less than the RAID stripe size write performance may be severely degraded.

This size must be divisible by the file system block size. The maximum value allowed is 512K and the minimum value allowed is the file system block size. The value default is 64K.

This value controls the amount of memory used to cache data from the file system. This parameter is shared by all file systems with the same block size.

Buffer Cache Auto DMA Read Length and Buffer Cache Auto DMA Write Length control the minimum I/O size for DMA transfers. That is, any smaller transfer will always go through the buffer cache.

The default value is 1MB.

Number of Readahead Buffers

This option controls the size of the read-ahead window used by the buffer cache.

The default value is 16 buffers with a maximum of 100. Using a value of 0 disables read-ahead.

Number of Threads

This option controls the number of dedicated background threads used by the buffer cache for performing I/O.

The default value is 8, with a minimum of 1 and a maximum of 100. Using a larger value can increase I/O concurrency in the buffer cache and therefore improve performance.

Seconds for Shared/ Non-Shared

Delay Atime Updates

The Attribute Flush Time parameters control the length of time attributes are held on the client before they are flushed back to the FSM (unless there is an explicit attribute request from the FSM).

The default values are 30 seconds for nonshared files (Attribute Flush Time, non shared), and 2 seconds for shared files (Attribute Flush Time, shared).

Setting these parameters lower will greatly increase the amount of metadata traffic between clients and the FSM. However, in circumstances where files are frequently shared on the SAN, setting the Attribute Flush Time Shared can result in other clients seeing size updates more frequently if a file is being written on one client and read on another.

A value of zero is invalid, and will result in using the default setting.

When this box is checked, the file system delays Atime (access time) updates when reading a file to the time when the file is closed. This cuts down on FSM metadata updates at the expense of coherency.

Low Water Mark High Water Mark Max. Entries Purge Period

(Seconds) Minimum Directory

Cache Size

Metadata Caches contain non-data information such as file names, sizes, update times, etc.

Tuning the low and high water marks and the frequency of purge passes can help certain large mix applications.

This option sets the size of the directory cache. Directory entries are cached on the client to reduce client-FSM communications during directory reads.

The default value is 10 MB.

Disk Device Labeler 4

The Disk Device Labeler utility lets you configure StorNext File System storage area network (SAN) disks. Use the Disk Device Labeler to create a list of disk labels, associated device names, and (optional) the sectors to use.

Note: Run the Disk Device Labeler on a system that has visibility to

all disk devices on the SAN.

The file system uses the volume labels to determine which disk drives to use. The label name written to a disk device must match the disk name specified in the Server Configuration utility. For more information, see

Server Configuration on page 96.

Caution: Modifying the label of a system disk may render the

system inoperable and require you to repair the volume. Only label disk devices that are intended for use with the StorNext File System SAN.

To run the Disk Device Labeler utility, on the Windows Start menu, click

All Programs > StorNext File System > Disk Device Labeler. The Disk Labeler

window (figure 41) appears.
