SAM-FS connection verification using NEC Storage

• Tested items

Sun StorEdge Utilization Suite 4.0 (SAM-FS) software products by Sun Microsystems are high-performance file managers that provide advanced storage management, protection, and recovery. As a result of the connection verification with the NEC Storage S series, NEC confirmed that the functions of SAM-FS operated properly.

Functions of SAM-FS

1. Archive function
   This function automatically copies files in online disk caches to archive media.
2. Release function
   By releasing disk blocks used by archive files, this function automatically manages magnetic disk caches of file systems in accordance with the usage rate threshold value specified in the site.
3. Staging function
   This function restores files to disk caches. When files released from disk caches are requested by users or processes, these files are automatically copied in online disk caches.
4. Recycling function
   This function clears archive volumes of invalid archive copies for recycling.

Verification environment

Server	Sun Microsystems server
OS	Solaris 9
HBA	NF9520-SH02 Driver:QAL2300-3(Rev4.0.9)
Array disk	NEC Storage S4300 F/W:020B SVP F/W:230 HA F/W:110C DA F/W:110C LUN configuration 4.1 GB x 2 RAID 1 for SAM-FS file systems 4.1 GB x 1 RAID 1 for ufs file systems
Software	SAM-FS Ver4.0

* Two units of HBA are installed in the server. The FC paths are used as dedicated paths by using the NEC Storage access control function so that the SAM-FS file system and the ufs file system do not conflict.
