.Part 3 Host and Storage System Rules HP SAN Design Reference Guide 785353-001

• Bidirectional, asynchronous remote replication with automated initial normalization between
source and destination (up to 150 ms one-way latency for asynchronous mirroring)
NOTE: HP SVSP uses built-in iSCSI; therefore, no additional devices are required to connect
HP SVSP to the intersite IP network. For network requirements for asynchronous replication,
see Table 124 (page 246).
• Synchronous mirroring across 100 km or (0.5 ms) one way over a Fibre Channel network
• Native support for up to four site campus, metropolitan, and continental disaster-tolerant
configurations
• Front end virtual disk size of 1 GB to 16 TB
• Virtual disk groups to preserve write-order consistency across multiple virtual disks using the
Continuous Access feature
• HP SAN API server-based CLI that allows scripted access to VSM
• I/O continuation (no application disruption) during normalization and merging, and data
migration to another pool in the domain or storage array
• Multiple-path failover support
• Seamless, online, software and firmware upgrades
• Selective storage presentation for SAN-based data zoning
• Connectivity to Fibre Channel 2, 4, and 8 Gb/s switches
• Support for up to sixteen 4-port arrays, eight 8-port arrays, or some other combination up to
128 ports

Hardware for a single SVSP domain
Hardware requirements are as follows:
• Minimum of one EVA, MSA, or XP
• High-availability dual-fabric environment (see “Level 4: multiple fabrics and device paths
(NSPOF)” (page 39))
