Overview of HP SFS 1–3

A typical Lustre file system consists of multiple Object Storage Servers that have storage attached to them.

At present, the Object Storage Servers are Linux servers, but it is anticipated that in the future the Object

Storage Servers may be storage appliances that run Lustre protocols. The Object Storage Servers are

internetworked over potentially multiple networks to Lustre client nodes, which must run a version of the Linux

operating system. Similarly, one or more MDS servers with associated storage are also interconnected with

client nodes. HP SFS Version 2.2 supports a single MDS server only.

1.2 Overview of HP SFS

HP SFS is a turnkey Lustre system that is delivered and supported by HP and has the following features:

• Provides Lustre services in an integrated and managed fashion.

• Provides access to Lustre file systems by way of Lustre client-server protocols over multiple

interconnects.

• Provides a single point of management and administration for the Lustre services.

• Allows legacy clients that can use only the NFS protocol to access the Lustre file system by configuring

a Lustre client as an NFS server of the Lustre file system (see Chapter 5 for more information).

• Allows Windows® and CIFS (Common Internet File System) client systems to access Lustre file systems

via Samba.

1.3 HP SFS client configurations

Client nodes that will use the Lustre file systems on an HP SFS system must have the HP SFS client software

and some additional software components installed on them. The client kernel must be at the correct level

to support the HP SFS client software; if necessary, the client kernel must be patched to the correct revision.

The client configurations that can be used with HP SFS fall into two categories:

• HP XC systems

HP provides prebuilt packages for installing the HP SFS client software on nodes that are running HP

XC System Software on Cluster Platform 3000, 4000, or 6000.

Section 1.3.2 provides details of the recommended HP SFS and HP XC configurations. Chapter 2

provides instructions for installing the HP SFS software on HP XC nodes.

• Certain Red Hat Enterprise Linux (RHEL) distributions and the SUSE® Linux Enterprise Server 9 SP3

(SLES 9 SP3) distribution

A number of RHEL distributions, and the SLES 9 SP3 distribution, have been tested successfully with

the HP SFS client software. In addition, HP has identified a number of other client configurations that

are likely to work with the HP SFS software, but have not been fully tested. The tested and untested

configurations are listed in Section 1.3.3.

For RHEL and SLES 9 SP3 configurations, you must use the supplied SFS Client Enabler to build the

HP SFS client software against the client kernel on the appropriate distributions, and then install the kit

that you have built. Chapter 3 provides instructions for building and installing the HP SFS client

software.

Note that the SLES 9 SP3 kernel does not need to be patched to function as an HP SFS client system;

therefore you do not need to reinstall the kernel or to reboot your system when you are installing the

HP SFS client software on a SLES 9 SP3 system.
