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 P2000 Dual I/O LFF Drive Enclosure
(AP843B) 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 (AP844B).
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, 288TB 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 the addition of RAID 0, particularly during writes.
Performance Performance numbers are a guideline as established by tests using RAW I/O in an Operating System
Agnostic test lab environment. 144 GB 15K SAS drives were used in a dual controller configuration of
12 vdisks consisting of twelve disks per vdisk, 1.6 TB volumes, and 3 volumes per host. 4 hosts directly
attached to the P2000 G3 array were used in this test configuration (results cannot be expected with a
single host). Results were achieved in Sequential Writes with 256K blocks; all random tests were based
on 8K block sizes.
NOTE: Number and type of applications, drive type and number of drives, operating system used, and
the number of hosts will affect overall performance. This table is provided strictly as a test-lab
