I've
placed some remarks next to the itemized requirements for the SAN so demonstrate
our ability to meet your needs. I have also created an architecture for
the SAN based on our 6TB building block. This hardware platform is suited
for larger capacity requirements and is a good balance of performance and
price/TB. There are other options that we can explore for different
scenarios. One option, althought it would be more costly, would be an
architecture that utilizes HP ProLiants for the storage nodes rather than
LeftHand's branded hardware.
The
proposed architecture consists of four 6TB storage nodes. This would yield
10TB of useable storage capacity and provide a significant level of data
protection that is not available for any other storage vendor. The
solution also contains a SAN Filer. This option will allow you to manage
the data on the SAN at a file level. It is powered by Microsoft Windows
Storage Server R2. The R2 edition provides some excellent capabilities to
assist with storage resource management. It will allow you to ability to
identify files that meet certain criteria such as age. It also contains
Single Instance Storage capabilities similar to what Exchange has. I have
attached a Microsoft paper that discusses SIS and how it provides improved
capacity utilization.
- 10 TB of Usable Data
Storage - Four 6TB NSM160's will yield
10TB of useable capacity if RAID 5 and SAN/iQ Level-2 data protection is
used
- Redundant
Management - The LeftHand User Interface is
a JAVA application that can be installed on multiple management
stations
- Redundant
Power - Each NSM260 has redundant power to prevent node
failure due to power loss
- Redundant Disk
Arrays - The proposed configuration
contains four active storage controllers. Up to two controllers can fail
concurrently.
- Asynchronous /
Synchronous Replication - Both capabilities are included
in the solution
- RAID 1/5/6/10 Support
or any combination of the four - LeftHand supports
RAID 0, 10, 5 & 50 that are combined with three levels of SAN/iQ data
protection levels
- File Management �
Ability to archive / delete files older than a set date and time on
demand - Proposed SAN Filer
provides this capability. The SAN Filer can also operate with Microsoft
Cluster Server for increased availability and increase file access
performance.
- Ability to loose
multiple Disk Drives and remain operational without interruption of
service - Volumes can remain
online even in the event of RAID5 double disk
faults
- Data Snapshot
capability - Included. There are
virtually no limits to the amount of snapshots that can be created and
retained.
- Storage device can
reside in multiple locations per virtual drive - LeftHand has the unique ability to create metropolitan
storage networks. This allows SAN volumes to be distributed across
multiple locations. With a LeftHand Metro-SAN, dataloss is will not
occur if a site failure caused by a disaster (naturual, fire, sprinkler
system, power failure).
LeftHand Configuration
- All prices are at standard retail cost for budgetary
purposes
