Overview1–4

HP SFS Version 2.2-0 software has been tested successfully with the following interconnect types:

• Gigabit Ethernet interconnect

• Quadrics interconnect (QsNet

) (from Quadrics, Ltd.)

• Myrinet interconnect (Myrinet XP and Myrinet 2XP) (from Myricom, Inc.)

• Voltaire InfiniBand interconnect (HCA 400) (from Voltaire, Inc.)

For details of the required firmware versions for Voltaire InfinBand interconnect adapters, refer to

Appendix A in the HP StorageWorks Scalable File Share Release Notes.

1.3.1 Interoperability with earlier versions of the HP SFS software

If you wish, you can upgrade your HP SFS server software to Version 2.2-0 while leaving some or all of your

HP SFS client systems at HP SFS Version 2.1-1. However, running different versions of the HP SFS software

on your servers and client nodes is normally considered a temporary configuration.

When an HP SFS system has been upgraded to Version 2.2-0, but one or more of the client systems served

by the HP SFS system has not yet been upgraded to HP SFS Version 2.2-0, the HP SFS servers and clients

must be configured as follows:

• The HP SFS servers must run in Portals compatibility mode.

• On client nodes that have been upgraded to HP SFS Version 2.2-0, the portals_compatibility

attribute must be set to weak.

When all of the client nodes and the HP SFS system have been upgraded to HP SFS Version 2.2-0, the

HP SFS system does not need to run in Portals compatibility mode and the portals_compatibility

attribute on all client nodes must be set to none.

HP does not support a scenario where the HP SFS client software is upgraded before the HP SFS server

software is upgraded.

1.3.2 HP SFS with HP XC systems

HP recommends that you upgrade both your HP SFS system and your HP XC systems to the latest versions

of the products. In the case of this release, this means that HP recommends the following:

• Upgrade all HP SFS server and client software to HP SFS Version 2.2-0.

• Upgrade all HP XC systems currently running the HP XC Version 2.1 stream or the HP XC Version 3.0

stream to HP XC Version 3.1 or HP XC Version 3.0 PK2.

However, to facilitate upgrade paths, HP supports interoperability between certain other HP SFS and HP XC

versions. The supported upgrade paths are shown in Section 1.3.2.1.
