volume in the cluster. With multiple iSCSI network interfaces across the cluster, a virtual IP address
across these interfaces presents the volumes as targets to iSCSI initiators.
Key features include:
• A cluster of pooled storage supporting up to 16 storage nodes. For larger configurations,
contact an HP storage representative.
• Two 1GbE ports per storage node (or optional upgrade to SPF+ 10GbE dual ports per storage
node).
• Multiple layers of high availability:
Multiple RAID levels within the storage node (RAID5, 6, and 10)◦
◦ Multiple Network RAID levels across the storage nodes on a per volume basis
(NetworkRAID 0, 10, 10+1, 10+2, 5, 6)
• Path failover capability:
Within the storage node, iSCSI interface bonding (active/passive, ALB, 802.3ad LACP).◦
◦ Within the cluster, Network RAID configured volumes support another path to another
storage node.
• HP StoreVirtual 4000 Storage comes with an all-inclusive enterprise feature set which includes:
storage clustering, Network RAID, application integrated snapshots, Remote Copy, and thin
provisioning.
• Multi-site cluster support—HP StoreVirtual 4000 Storage can be deployed in clusters that are
stretched across multiple racks, data rooms or data centers. These installations require:
◦ A stretched 1 GbE or 10 GbE Ethernet network
NOTE: 50 MB/s (400 Mb/s) of bandwidth per storage node pair needs to be allocated
on the 1 GbE network between the locations. 200 MB/s (1,600 Mb/s) of bandwidth per
storage node pair needs to be allocated on the 10 GbE network between the locations.
Network latency among storage nodes cannot exceed 1 ms.
