HP LU N Configuration and Security Manager
HP LUN Configuration and Security Manager provides add itional LUN configuration
and security o ptions. You can add and delete paths, create custom-sized volumes, and
configure fool
proof LUN security that provides controlled, secure access to data stored
on the disk ar
rays—preventing unauthorize d ser vers from accessing your data. It also
configures th
e arrays to m e et changing storage requirements and enables users to share
a single Fibre Channel array among multiple servers.
HP LUN Configuration and Security Manager allows you to:
• Create, define, and configure LUNs on the disk arrays
• Consolida
te LUNs (combine up to 36 LUNs)
• Create small size LUNs to accommodate data locked into cache
• Establish security at the LUN level so that you can enable multiple server
connecti
vity to the disk arrays
• Hide LUNs assigned to one server from other ser vers during IOSCAN operations
• Configure LUSE and create custom volume sizes
HP Cache LUN
Cache LUN lets you reserve areas of memory cache to store frequently accessed
information. It improves file access times and enables faster data transfers. Assigning
information to on-board cache speeds up access to your d ata because cache-resident
data is available at host da ta transfer speeds for both read and write operations.
Cache L UN redirects I/O requests from the disk drives to data locked in the SVS200
cache. It’s transparent, simple to implement, and it delivers immediate performance
gains. CachememoryforCacheLUNcanbesetaslowasonelogicalblockor512
MB. As your needs grow, you can increase cache volumes in increments of one logical
block to a maximum of 1,024 cached volumes.
