Subject: Windows file server changes
 
 Our Windows file server is a dual-processor 733 MHz Dell server with 1 GB of memory
 and redundant power supplies. Over the past few months, several hardware
 changes have been completed:
 
  - addition of new disks
 
  - complete rebuild of all user data RAID containers
 
  - removal of the old 8-bay storage enclosure
 
 Unlike the Unix server, the Windows server has hardware RAID controllers that
 allow redundant data volumes (data integrity can be maintained should one
 disk be lost). The server was originally purchased in fall of 2000 with one
 rack-mounted 8-bay disk enclosure for hot-swappable disks. It went into
 production in the April/May 2001 time period, replacing chem-nt1 as a file
 server. In summer of 2001, a rack-mounted 12-bay enclosure for hot-swappable
 disks was added.
 
 In recent months, more disk space was added. After a complete rebuild of the
 RAID containers, the current disk configuration is as follows:
 
  o 3x9 GB RAID5 array for boot disk (usable capacity: 17 GB)
  o 8x16 GB RAID5 array (usable capacity: 118 GB) with 16 GB and 30 GB
    partitions for research groups who purchased disk space; the remainder
    (approx. 73 GB) is for group shares, software and scratch space
  o 6x36 GB RAID5 array for all individual U: shares (usable capacity: 169 GB)
 
 This makes the total usable disk space 304 GB. All disks are 10,000 rpm Ultra-160
 on Ultra-2 (80 MB/s) SCSI channels.
 
 Data was moved from older drives to the new RAID volumes in several
 over-night projects on a live system, largely unnoticed by users. The old
 external non-hot-swappable non-rack-mountable 8-bay enclosure was removed and
 will be used for other purposes.
 
 The Windows file server is running Windows2000 Advanced Server, Service Pack
 2.

 of the Windows server.
