HP StorageWorks SAN Virtualization Services Platform 3.0 release notes (5697-0404, April 2010)

• 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 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 synchronous mirror virtual disks per DPM group: 128 (512 with 4 DPM

groups)

• Maximum number of total active asynchronous remote copies, snapclones, and concurrent migration

jobs per SVSP system: 512

• 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

SVSP back-end capabilities and limitations

• Back-end array capacity of the SVSP system: 2 PB

• Total back-end target ports: 128 (32 arrays with 4 ports per array)
