HP StorageWorks SAN Virtualization Services Platform 3.0.4 Release Notes (5697-0763, November 2010)

SVSP system capabilities and limitations
• Maximum capacity per system: 2 PB
• Maximum number of VSMs per system: 2
• Maximum number of DPMs per system: 4 DPM groups with maximum of 2 DPMs per group
• Maximum number of array ports: 128
For example:
• 32 arrays with 4–ports each
• 16 arrays with 8–ports each
• Any combination totalling up to 128 ports
• Maximum number of servers (with 2 HBA ports/server) per DPM pair: 512 (2048 with 4 DPM
pairs)
• Maximum number of tasks per domain (total snapclones, async mirrors, and internal migrations):
512
• Maximum HBAs per server: 8 (Windows/DSM limit)
• DPM maximum number synchronous mirror groups: 128 per DPM group (512 with 4 DPM groups)
• Defined maximum distances:
• Asynchronous mirrors are supported up to 150 ms one-way separation (iSCSI only), and min-
imum bandwidth set to 3 Mbps.
• Synchronous mirrors supports up to 0.5 ms one-way separation (Fibre Channel transport only).
• DPM maximum full performance capacity without synchronous mirror: 90 TB
• DPM maximum synchronous mirror virtual disk full performance capacity using 2 tasks: 45 TB
SVSP front-end capabilities and limitations
• Front-end presented capacity of the SVSP system: 8 PB (2 PB physical capacity and 2/4/8 PB
thin capacity with 2 PB per DPM group)
• Total initiator ports: 1024 per pair of DPMs (DPM group)
• Maximum number of remote ports (targets and initiators): 255 per local port, 1024 total
• Maximum number of virtual disks (including snapshots, snapclones, 4 paths): 4093 + 3 setup
virtual disks per DPM pair.
• Maximum number of virtual disks per host: 255 (LUNs 1–255)—depending on operating system
• Maximum size of virtual disk: 16 TB
• Minimum size of virtual disk: 1 GB
• Maximum number of PiTs per virtual disk: 32 at 10–minute intervals or 64 at 60–minute intervals
• The minimum interval between point in time (PiT) copies is 10 minutes. This also limits the minimum
asynchronous replication (remote mirror) recovery point objective to the same 10–minute interval.
• Maximum number of mirror PiTs (required PiTs + PiTs alert) on either source or destination virtual
disk or virtual disk group: 64
• Total number of PiTs per SVSP system: 4096
• Maximum snapshots per PiT: 32
• Maximum snapshots per virtual disk: 64
• Maximum front-end presentations per DPM: 8192 (4096 LUNs with 2 paths per virtual disk per
DPM)
• Maximum number of front-end paths (I-T-L) per virtual disk: 64 per DPM
• Maximum number of virtual disk members in a virtual disk group: 32
