Scalability
The MSA2300fc G2 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 5.4 TB SAS or 12 TB
SATA, expandable to 27 TB SAS or 60 TB SATA with the addition of a
maximum of four MSA2000 3.5-inch Drive Enclosures.
Small Form Factor configurations can scale from 3.5 TB SAS or 6 TB
SATA. With the addition of three MSA70 JBODs, the MSA2324fc G2
can support 14.4 TB SAS or 24.7 TB SATA.
Users may configure a 24-drive MSA2324fc G2 SFF array head with up
to three 12-drive LFF MSA2000 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.

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
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 in a lab
environment. 96 72 GB 15K SAS drives were used in dual controller
configurations of eight 12 Disk vdisks, eight 806 GB volumes, and two
volumes per host.
Number and type of applications along with the number of hosts will affect
overall performance.
