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 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 P20000 3.5-inch disk enclosures. This is an excellent
method for a configuration that support 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 MSA2000 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. A total of 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 FC 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. The
test results shown for the P2000 G3 are preliminary and designed to give
a reference point for comparisons. They will be reposted as necessary.
