*********************************************** Minimum Salient
Characterist ics Purchase a data storage / storage area network and
backup solution for Windows NT and UNIX servers. The solution must meet
the following specifications: 1. The Storage Area Network (SAN) must
provide the following core services: -Full Fibre-Channel Support
-Cross-Platform Support (Windows NT, UNIX) -Protection against loss of
data stored in cache. -Multiple concurrent RAID level (0, 1, 0+1, 5)
support. -Multiple stripe depth support. -Dual active/active RAID
controllers. -Dynamically adjusted look-ahead read cache. -Multiple
independent processors per RAID controller. -Mirrored/synchronized
write cache (Dedicated 100MB/sec cache bus. -Fibre Channel host
interface (100MB/sec). Connected via Fibre channel. (See Question 9) 2.
The SAN must provide volume mapping. This mechanism protects valuable
data from accidental or inappropriate access by numerous hosts. -Volume
mapping allocates storage volumes to specific hosts via world wide host
names. -Host systems see only the volumes to which they are assigned.
-Volume mapping provides an absolutely secure method of controlling
host access to data. -Allows storage volumes to be dynamically re-all
ocated among host systems. -Must be implemented in upgradeable array
firmware which: -Provides a single point of control for host access to
volumes of storage. -Supports one-to-one and many-to-one
configurations. -Requires no host-base software. 3. The SAN must
provide extended checksum data with each sector to confirm that
error-free data is returned to the host. 4. The SAN must contain a
process that logs all write transactions to a nonvolatile log to ensure
that all writes are completed even in the event of a power
interruption. Transactions are to be stored until data has been safely
written and verified to storage. (See Question #23) 5. Upon power
interruption, the SAN must contain a feature that copies cache
contents, including mirrored data and array error logs to a special
dedicated hard disk drive mounted directly on each RAID controller.
Upon power restoration, the cache contents are restored, incomplete
writes are reconstructed and written to disk, and normal operation
resumes even with a controller or drive failure. 6. The SAN must
perform Data Consistency Checks. Data consistency checking (DCC)
continually monitors the disk drives for bad blocks and automatically
relocates data to circumvent potential data corruption or loss. (See
Question #22) 7. The SAN must perform duplexed cache writes. This
process writes incoming data into two separate caches simultaneously in
one operation. It improves write cache operation by eliminating
overhead. No write cache performance penalties can be experienced in
active/active controller configurations. 8. The SAN must allow user
configuration of the following items: -Array group width (number of
drives in a group) up to 16. -Stripe depth selectable per array group.
-Stripe depth from 1 to 96 blocks. -Stripe depth to match application
I/O profiles for peak performance. -RAID level per array group.
-Logical volumes (Up to 32). -Volume size selectable in blocks,
megabytes or gigabytes. -Pooled hot spares. 9. The SAN must contain a
dynamically adjusted write-gathering cache algorithm that allows the
SNA to behave like a RAID 3 system when dictated by data or process
type. (This is extremely important when doing database loads, database
restores, or sequential writes.) A RAID product that provides actual
RAID 3 will meet this requirement if the pr oduct satisfies the
requirement to dynamically adjust write-gathering memory dictated by
data or process type for execution of database loads, database
restores, or sequential writes. (See Question #21) Oracle and SQL
Server databases, graphical images, html reports, office automation
files and application executables will be stored on the RAID. (See
Question #27) 10. CIFS and NFS file services must be fully supported.
11. The network attached storage devices must integrate with the
existing fast Ethernet and CDDI networking infrastructure. Please
disregard this requirement as stated. The intent on item 11 was to
ensure that the host bus adapters for the SAN would coexist and operate
with the fast ethernet and Copper Data Distribution Interface (CDDI)
network interface cards presently in the servers. (See Question #1 and
#6) 12. The solution must include centralized monitoring and statistic
retrieval software/hardware. 13. The backup solution must consist of a
DLT7000 tape jukebox with a minimum of 4 drives expandable to 7
drives. The backup and restore software must be capable of execution on
a Windows NT server with agents for Windows NT, UNIX, Orac le Database,
and SQL Server. Data backups and restoration must be performed directly
from the SAN via Fibre-channel and Ethernet. Yes, the SAN solution is
required to have agents capable of backing up online Oracle and SQL
Server databases (See Question # 4) The on-line (hot) backups are to be
performed over the SAN (private network). Six to 12 hour window per day
(24 hour) period. (See Question #24) The SAN will function as the data
storage for the servers and the SAN and Oracle / SQL Server databases
agents will utilize the DLT 7000s for online backups. (See Question
#7) Total number of disk drives and spindle size is as follows: 36 disk
drives and 18-36 GB per drive (See Question #13) Total number of slots
for DLT media in the library is as follows: Four DLT 7000 in a unit
scalable to 7 drive units. (See Question #14) Total number of required
DLT media is as follows: Ninety 35/70 GB cartridges (See Question #15
