Family Information

HP StorageWorks P2000 G3 Modular Smart Array Systems

Drives available

The P2000 G3 controllers support both the P2000 3.5-inch Large Form Factor (LFF) drives, and the

 

HP ProLiant 2.5-inch Small Form Factor (SFF) drives.

 

Serial Attached SCSI (SAS) enterprise-class drives are designed for high demand, 24x7

 

usage.

 

SAS Midline and SATA Midline are usually reserved for archival of data as they are both

 

relatively inexpensive and are available in very large capacities.

 

The HP entry-level family of arrays can accommodate both SAS and SATA drives within the same

 

enclosure making it ideal to have both business-critical, high activity files on SAS drives while using

 

Snapshot, clone, or Remote Snap capability to keep back-up or archival data on the less expensive

 

drives.

 

For investment protection, the controllers will support single and dual port SAS & SATA drives in a

 

legacy single - or dual - domain MSA70. This support allows current owners of MSA70s to migrate

 

their single port drives (in their MSA70 only, not into the array head) to be attached to a P2000 G3

 

FC or SAS. They can only cascade to another single I/O MSA70. This is not a data-in-place

 

transition, and overall performance could be impacted.

 

SAS drive performance can be approximately 30% greater than SATA performance on sequential

 

host I/O. SAS performance excels in sequential lower latency response time and random I/O per

 

second transaction performance due to higher rpm disk speeds yielding lower seek times. SAS

 

drive random performance is generally twice that of SATA drives.

 

NOTE: P2000 and MSA2 3.5-inch Large Form Factor (LFF) drives are for use only in the P2000 G3

 

or MSA2000 models. The 2.5-inch Small Form Factor (SFF) drives are supported only with the

 

P2000 G3 or the MSA2300 G2 controllers and are common with and are the same part numbers as

 

the ProLiant hot-plug 2.5-inch drives.

Optional Disk

Just as the user has a choice of chassis for the array head (LFF and SFF drive bays, AC or DC

enclosures

powered), so also do they have a choice of expansion disk enclosures accommodating either drive

 

size.

 

(NOTE: these are not supported as part of a NEBS-certified with the MSA Carrier Grade Chassis.

 

There is a certified JBOD listed in the Carrier-grade section)

 

P2000 3.5-inch drive enclosure. This 2U unit has twelve LFF (3.5-inch) drive bays and accepts for

 

P2000 dual-ported SAS and SATA drives. The pre-configured HP StorageWorks P2000 Dual I/O

 

LFF Drive Enclosure (AP843A) has two I/O modules and supports both single and dual controller

 

arrays. If a single I/O disk enclosure model is desired, the appropriate chassis should be purchased

 

along with a single I/O module (AP844A).

 

This 3.5-inch drive enclosure can be attached to either the P2000 G3 FC or SAS LFF or SFF

 

array head.

 

Each configured model ships standard with two .5m mini-SAS to mini-SAS cables for

 

cascading to other P2000 drive enclosures

 

Up to seven P2000 3.5-inch enclosures can be attached to a P2000 G3 FC, FC/iSCSI

 

Combo, or SAS controller in the array head.

 

D2700 2.5-inch drive enclosure. This 2U storage enclosure (AJ941A) is designed to support

 

twenty five ProLiant 2.5-inch Universal form factor (SFF) 6Gb SAS or SATA hard drives. It ships

 

standard with dual I/O modules installed.

 

This 2.5-inch drive enclosure can be attached to a P2000 G3 controller (SFF or LFF) array

 

head

 

The D2700 enclosure ships with a two .5m miniSAS to miniSAS cable.

 

Up to five D2700 may be attached to the P2000 G3 array head, given total support for 149

 

SFF drives.

Scalability

The P2000 G3 FC, Combo FC/iSCSI, SAS, 1 Gb or 10GbE iSCSI controllers are designed to allow

 

an installation to begin with smaller capacity and be able to grow gradually as needed. The flexibility

 

of SAS or SATA drive technology, form factors, sizes, speeds, and costs per GB allows a system to

 

easily fit in almost any budget.

Large Form Factor configurations can scale up to 7.2 TB SAS or 24 TB SATA, expandable to

57.6TB SAS or 192 TB SATA with the addition of a maximum of seven P2000 3.5-inch Drive Enclosures.

Small Form Factor configurations can scale from 7.2 TB SAS or 12 TB SATA. With the addition of five D2700 JBODs, the P2000 G3 FC can support 44.7 TB SAS or 74.5 TB SATA. Users may configure a 24-drive P2000 G3 SFF array head with 12-drive LFF P2000 3.5-inch disk enclosures. This is an excellent method for a configuration that supports fast SFF enterprise-class SAS drives in the array head, combined with economical LFF drives staged for archival purposes, all in the same array.

Qualification of larger capacity drives is ongoing.

Vdisks

Vdisks can span across multiple enclosures, where drives used in the Vdisk can be contained in

 

different enclosures. The maximum number of drives that can be used in RAID 1 Vdisk is 2; RAID

 

0, 3, 5, 6, and 10 is 16; and for RAID 50 Vdisk is 32.
