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 port SAS &
SATA drives in a legacy single-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
an MSA2000fc G2. 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
MSA2300fc G2 controller and are common with and are the same part
numbers as the ProLiant hot-plug 2.5-inch drives.
Optional Disk
enclosures
Just as the user has a choice of chassis for the array head (LFF and SFF
drive bays, AC or DC 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. )
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 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 or FC/iSCSI Combo 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.
