Re: Totally confused about Service Guard Rac and SFRAC

there isn't anything called SFRAC in cluster world? But ServiceGuard Extension for RAC(SERAC) which deals with the clustered volume in RAC mode.

Interms of UNIX administration, Oracle RAC has less to do compare with SERAC. But the implemenation may not be as easy as SG which is most common

Re: Totally confused about Service Guard Rac and SFRAC

The HP product to support Oracle RAC (9i, 10g and 11g) is called SGeRAC. SGeRAC is an add-on to the Serviceguard itself. You can also implement CFS (Clusterd File SYstem) with SGeRAC which gives you a lot of capabilities. See more here:
http://www.hp.com/go/SGeRAC

and here:

Re: Totally confused about Service Guard Rac and SFRAC

Veritas is now part of Symantec and not owned by HP. The SGeRAC with SMS (Storage Management Suite) is a co-operation between Symantec (Veritas) and HP.
For more information regarding SMS see here:

Keep in mind SMS is not designed only for Oracle RAC. You can use SMS for many other applications, such as replacing an NFS server etc.

Re: Totally confused about Service Guard Rac and SFRAC

HP don't own Symantec.

HP Products:
LVM - Logical Volume Manager
Serviceguard - Cluster Software for HP-UX (& Linux)
Serviceguard Extension for Oracle RAC (SGeRAC) - cluster software to allow Serviceguard to provide cluster services for Oracle RAC. Without any other HP components discussed below you are limited to just using Shared LVM as raw volumes for Oracle RAC.

Symantec (Veritas) Products:

VxFS - Veritas Filesystem
VxVM - Veritas Volume Manager
VCS - Veritas Cluster Server
CVM - Cluster Volume Manager - VxVM configured for concurrent access in a cluster
CFS - Cluster Filesystem - VxFS configured for concurrent access in a cluster
ODM - Oracle Disk Manager - Interface between VxFS and Oracle to allow asynchronous IO for near-raw performance

Symantec takes the set of products described above and warps them up into a bundle called "Storage Foundation for Oracle RAC" or SFRAC for short.

HP OEM's some of the Symatec products to create several different bundles all of which have the headline "Serviceguard Storage Management Suite" - there are about 6 different bundles, but the one you would be interested in is "Serviceguard Storage Management Suite for Oracle RAC CFS". This provides a cluster filesystem for Oracle RAC, with Serviceguard providing cluster services for CVM, CFS and for Oracle RAC itself.

So the key difference between SFRAC and "Serviceguard Storage Management Suite for Oracle RAC CFS" is the cluster software - VCS or Serviceguard.

For the HP side of things, this WP might help:

Re: Totally confused about Service Guard Rac and SFRAC

I was under the impression that HP bought symantec - I know what SFRAC and Serviceguard, etc - I use them daily - was just confused when I thought that HP owned SFRAC and VCS
