Performance management software

Cache LUN XP lets you reserve areas of memory cache on the XP disk

arrays 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 data because cache-resident data is available

at host data transfer speeds for both read and write operations.

Cache LUN XP redirects I/O requests from the XP disk drives to data

locked in the array's cache. It's transparent, simple to implement, and it

delivers immediate performance gains. Cache memory for Cache LUN XP

can be set as low as one logical block or 512 MB. As your needs grow, you

can increase cache volumes in increments of one logical block to a

maximum of 1,024 cached volumes. The software also integrates with

Command View XP for web-based anytime, anywhere access.

Auto LUN XP provides monitoring and disk usage analysis for your disk

array based on user thresholds. Auto LUN develops a plan to migrate

impacted data volumes to lower usage LUNs, using the data acquired

during monitoring. You can perform the migration manually or

automatically.

Performance Advisor is an Internet application used to monitor real-time

performance of the HP StorageWorks XP family of disk array products.

Using a simple, browser-based interface, you can quickly customize

performance data collection and set performance alarms. Performance

Advisor provides real-time and historical data on:

• LDEV I/Os

• Front-end and back-end port utilization
