port SAS & SATA drives in a single-domain MSA70. This support allows current
owners of MSA70s to migrate their single port drives (in their MSA70 only) to
be attached to an MSA2300fc. They can only cascade to another single I/O
MSA70. This is not a data-in-place transition.
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.

MSA2 3.5-inch Large Form Factor (LFF) drives are for use only in the
MSA2000 family. The 2.5-inch Small Form Factor (SFF) drives are supported
only with the MSA2300fc G2 controller and are common with and are the
same part numbers as the ProLiant optional 2.5-inch drives.

Just as the user has a choice of chassis for the array head (LFF and SFF drive
bays), so also do they have a choice of expansion disk enclosures
accommodating either drive size.

MSA2000 3.5-inch drive enclosure
. This 2U unit has twelve LFF (3.5-inch)
drive bays and accepts for MSA2 dual-ported SAS and SATA drives. One
model (AJ749A) has a single I/O module that matches with a single controller
array head, giving a single path to the drives. The second model (AJ750A)
comes standard with two I/O modules installed, required when paired with a
dual controller array head, giving two paths to the drives for higher
availability.
This 3.5-inch drive enclosure can be attached to either the MSA2312fc
or MSA2324fc array head. In addition it continues to support the
MSA2000i and MSA2000sa.
Each model ships standard with two .6m SAS to SAS cables for
cascading to other MSA2000 drive enclosures
For connection to either form-factor MSA2300fc array head, miniSAS to
SAS cable(s) must be purchased.
The single I/O model can be upgraded to a dual model with the
purchase of an additional MSA2000 Drive Enclosure I/O module
(AJ751A). No cable is included with this upgrade.
Up to four MSA2000 3.5-inch enclosures can be attached to an
MSA2300fc G2 controller in the array head.
MSA70 2.5-inch drive enclosure
MSA70 2.5-inch drive enclosureMSA70 2.5-inch drive enclosure
MSA70 2.5-inch drive enclosure
. This 2U storage enclosure (418800-B21) is
designed to support twenty five ProLiant 2.5-inch Universal form factor (SFF)
SAS or SATA hard drives. It ships standard with a single I/O module installed.
This 2.5-inch drive enclosure can only be attached to an MSA2324fc
G2 controller (SFF)array head. It cannot be attached to the MSA2312fc
(LFF) or the MSA2000i or MSA2000sa models.
The MSA70 enclosure ships with a single .5m miniSAS to miniSAS
cable.
To support a dual controller MSA2124fc array head, the user needs to
purchase and install an MSA70 Dual Domain I/O Module (AG779A).
This option ships standard with an additional .5m miniSAS to miniSAS
cable.
Up to three MSA70s may be attached to the array head, given total
support for 99 SFF drives.
