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 Storage 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. Both the P2000
and the D2700 disk enclosures can be hot-added to an operating array.
(
NOTE:
these are not supported as part of a NEBS-certified configuration 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 storage enclosure (AJ941A) is designed to support twenty five
Storage 2.5-inch Universal form factor (SFF) 6Gb SAS or SATA hard drives. It ships standard with dual I/O
modules installed.
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, 36TB SAS MDL or 24 TB SATA,
expandable to 57.6 TB SAS, 384 TB SAS MDL 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 21.6 TB SAS, 24 TB SAS MDL or 12 TB SATA MDL.
With the addition of five D2700 JBODs, the P2000 G3 can support 134 TB SAS, 149 TB SAS MDL or
74.5 TB SATA MDL.
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.
LUNs
The HP 2000 family of arrays supports 512 LUNs (total volumes in a dual controller system) and LUN sizes
up to 64 TB depending on the RAID configuration chosen. The array supports expansion and deletion of any
LUN.
RAID 0, 1, 3, 5, 6, 10, 50
In addition to the usual RAID levels, the P2000 G3 features several important additional levels. RAID 6 is the
highest level of RAID protection. It allocates two sets of parity data across drives and allows simultaneous
write operations. It can withstand two simultaneous drive failures without downtime or data loss. RAID 10 is
mirroring and striping without parity. It is the most popular of the multiple RAID levels, allowing large arrays
with high performance in most cases and superior fault tolerance. RAID 50 combines the block striping and
parity of RAID 5 with the straight block striping of RAID 0, yielding higher performance than RAID 5 through
