STAFF REPORT
REQUEST: APPROVAL OF PURCHASE OF STORAGE ATTACHED
NETWORK (SAN) FOR PROVIDING BETTER MANAGEMENT
AND PROTECTION OF CITY COMPUTER DATA FILES
SUBMITTED BY: DOUG VAN GELDER, DIRECTOR OF INFORMATION SYSTEMS
DATE: JUNE 12, 2006
CONTENTS: QUOTE FROM GATEWAY COMPUTERS FOR A HITACHI DATA
SYSTEMS SAN SOLUTION
Recommendation:
By Minute Motion, approve the purchase of Hitachi Data Systems Storage
Attached Network solution from Gateway Computers in the amount of
$67,211 and applicable taxes. Funds are available in Account No. 110-
4190-415-4040.
Discussion:
As the City's computer needs and reliance on computer files have increased, additional
computer file servers have been added to the City's network. Computer file servers and
their storage (hard drives) can only be used by applications loaded on the computer file
server that hosts (contains) the applications. Newer technology allows computers to use
storage (hard drives) in a "pool" that can be dynamically allocated between computer
file servers. This allows staff to allocate storage where it is needed instead of guessing
how much space may be needed by the server when it is purchased. As servers are
replaced, the new servers are "pointed" at the existing data files from the server that
was replaced.
In addition to allocating space, it will provide for better data backups and recovery. Data
will now backup to disk before being backed up to tape. This will speed up the backup
process and allow backup to tape to occur without interfering with production use of the
data files. Files can be recovered from disk; a much faster process. Tape backup will
still be used as a secondary source for disaster planning and recovery.
