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 or 10GbE controller is 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
57.6 TB 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 FC 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.
LUNs The HP StorageWorks 2000 family of arrays supports 512 LUNs (total volumes in a dual controller
system) and LUN sizes up to 16 TB. 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
comparison. Note: These numbers reflect a full array configuration with the maximum number of
front-end ports, disks, and controllers. The test results shown for the P2000 G3 are preliminary and
designed to give a reference point for comparisons. They will be reposted shortly when finalized.
