13 SAN Virtualization Services Platform

This chapter describes HP SVSP. HP SVSP is a scalable platform that provides:
Centralized management of the HP SVSP domain and its objects
Multitiered data protection
Nondisruptive data provisioning
Local and remote replication and volume management
HP SVSP improves array utilization by creating storage pools that span multiple arrays. Storage pools
are managed using a single interface and are provided with a rich set of virtualization features, even
though they span multiple physical devices from multiple vendors.
After a storage pool is defined, a volume of storage, called a virtual disk, can be allocated from the
storage pool to a server. The virtual disk size is flexible and independent of the size of physical storage
component or any logical unit in the SAN.

Features

HP SVSP offers the following features:
The ability to create storage pools that span up to 16 arrays
SAN storage-based local and remote replication
Thin Provisioning for designated virtual disks, even if the array does not support Thin Provisioning
A centralized VSM GUI to manage all objects in the domain, providing a single view of data on
multiple arrays
Data migration between arrays from multiple vendors
Disaster recovery for a site, array, or virtual disk
Bidirectional, asynchronous remote replication with automated initial normalization between source
and destination
NOTE:
HP SVSP uses built-in iSCSI; therefore, no additional devices are needed to connect HP SVSP to
the intersite IP network. See
Synchronous mirroring across 100km or (0.5ms) one way over a Fibre Channel network
Native support for up to four site campus, metropolitan, and continental disaster-tolerant
nl
configurations
Virtual disk size of 1 GB to 2 TB
Virtual disk groups to preserve write-order consistency across multiple virtual disks
HP SAN API server-based CLI that allows scripted access to VSM
I/O continuation during normalization and merging, and data migration to another pool in the
domain
Multiple-path failover support
