Modular Chassis Modular Chassis Modular Chassis Modular Chassis 2U, 12 Large Form Factor drive bays, accommodating MSA2 SAS and SATA
hard drives (MSA2000-specific). Comes standard with one or two controllers.
Drives available Drives available Drives available Drives available Serial Attached SCSI (SAS) enterprise-class drives designed for high volume,
24x7 usage. Serial-ATA (SATA) are usually reserved for archival of data as
they are both relatively inexpensive and are available in very large capacities.
The MSA2000 family of arrays can accommodate both SAS and SATA drives
within the same enclosure making it ideal to have both business-critical, high
activity files on SAS drives while using snapshot or clone capability to keep
back-up data on the less expensive drives. SAS drive performance can be
approximately 30%greater than SATA performance on sequential host IO.
SAS performance excels in sequential lower latency response time and
random IO per second transaction performance due to higher rpm disk
speeds yielding lower seek times.
NOTE: NOTE: NOTE: NOTE: MSA2 3.5 inch Large Form Factor (LFF) drives are for use only in the
MSA2000 family.
Scalability Scalability Scalability Scalability Up to 3.6TB SAS or 12TB SATA, expandable to 14.4TB SAS or 48TB SATA
with the addition of a maximum of three MSA2000 3.5 inch Disk Enclosures.
LUNs LUNs LUNs LUNs The MSA2000 family of arrays supports 256 LUNs and LUN sizes up to
16TB. The arrays support LUN expansion and deletion of any LUN.

In addition to the usual RAID levels, the MSA2000 family 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
