HP StorageWorks SAN Virtualization Services Platform 2.1 release notes (5697-8060, March 2009)

Capabilities and limitations
For a glossary of terms used in this document, refer to other SVSP documentation like the HP
StorageWorks SAN Virtualization Services Platform administrator guide.
SVSP system capabilities and limitations
• Maximum capacity per system: 1 PB
• Maximum number of VSMs per system: 2
• Maximum number of DPMs per system: 2 DPM groups with 2 DPMs per group
• Maximum number of array ports: 64
For example:
• 16 arrays with 4–ports each
• 8 arrays with 8–ports each
• Any combination totalling up to 64 ports
• Maximum number of servers (with 2 HBA ports/server) per SVSP system: 512
• Maximum HBAs per server: 8 (Windows/DSM limit)
SVSP front-end capabilities and limitations
• Front-end presented capacity of the SVSP system: 1 PB (Maximum of back-end. See the following
back-end section for additional limitations.)
• Maximum number of virtual disks (including snapshots, snapclones, 4 paths): 4093 + 3 setup
virtual disks
• Maximum number of virtual disks per host: 255 (LUNs 1–255)—depending on operating system
• Maximum size of virtual disk: 2047 GB
• 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 initiators per virtual disk: 64 (32 dual-port hosts) if supported by OS and
multipath drivers
• Maximum number of virtual disk members in a virtual disk group: 32
• Maximum number of total active asynchronous remote copies, snapclones, and concurrent migration
jobs per SVSP system: 256
• Maximum number of asynchronous mirror tasks (remote copies) per source virtual disk: 3
• Maximum number of cross-connected systems or domains for management over IP: 4
