HP Serviceguard Storage Management Suite bundles with VxVM and VxFS
The following Serviceguard Storage Management Suite bundles all support clusters of up to 16 nodes but differ from each other based on the Veritas Storage Foundation version they include:
∙Veritas Storage Foundation Standard
∙Veritas Storage Foundation for Oracle
∙Veritas Storage Foundation for Oracle Enterprise
T2771xx: HP Serviceguard Storage Management
The HP Serviceguard Storage Management (SGSM) bundle integrates Serviceguard high-availability clustering with Veritas Storage Foundation Standard, which includes full versions of Symantec’s VxVM and VxFS. This entry-level bundle includes the following individual components:
∙HP Serviceguard
∙HP Serviceguard Manager
∙HP Enterprise Cluster Master Toolkit
∙Veritas File System
∙Veritas Volume Manager
∙Veritas Dynamic Multi-Pathing (DMP)
∙Veritas Enterprise Administrator (VEA)
∙Storage Checkpoints
∙Veritas Storage Rollback
This bundle is suited for users with non-Oracle database environments who want to use the basic Veritas Storage Foundation products in their Serviceguard cluster but do not have a need for CVM, CFS, or any of the premium Storage Foundation components.
Users looking for features that are not available in a Serviceguard cluster with HP LVM might choose this bundle. One important high availability feature—the DMP—that comes with this and all other bundles is active/active path failover to storage devices that support this feature. The DMP feature of VxVM provides path failover and load balancing. It balances I/O across all available paths between a server and a storage array. For SG SMS versions on HP-UX 11i v2, the LVM alternate physical links feature, PVLink, provides no load balancing and only active/passive path failover. For HP-UX 11i v3 and beyond, the I/O stack provides DMP or load balancing. DMP, along with PVlinks, provides backwards-compatibility with current environments and additionally full load balancing.
Note
With HP-UX 11i v3, you have the option of Native Multi-Pathing in addition to the storage multi-pathing options mentioned earlier. For detailed information, see “Storage Multi-Pathing choices in HP-UX Serviceguard Environments” available at http://docs.hp.com/en/11822/storagemulti- pathing-HPUX-SG.pdf
Note that this bundle does not include CVM or CFS. For this reason, this bundle is well suited for failover applications but not for active/active multi-instance applications.
