Restrictions & recommendations for binding disks into LUNs:

LUN to bind Restrictions and recommendations ----------- Any LUN You can bind only unbound disk modules. All disk modules in a must have the same capacity to fully use the modules' storage space. --- In AX-series storage systems, binding disks into LUNs is not supported.[...]

How to reduce power consumption on DMX?

There are two primary ways to reduce power consumption by carefully configuring the storage array itself and by taking advantage of EMC tools. Useful tips that will help to design an efficient DMX-3 array, including: 1) Minimizing DA pairs required. 2) Using more daisy chain storage bays to obtain needed capacity with fewer DA pairs. 3) Fully loading drive enclosures with drives (15) to reduce excess power overhead from cooling, logic, and power supply load efficiency.

Best Practice for Oracle and Volume Manager for EMC Symmetrix DMX-3 Storage

Veritas Disk Group Configuration Guidelines:- 1) Use multiple Disk Groups—preferably a minimum of four; place the DATA, REDO, TEMP, UNDO, and FRA archive logs in different (separate) Veritas Disk Groups 2) Optimally, use RAID 1 for tier 1 storage[...]

Performance Tunning

Performance tuning has always been a challenge for System administrators and Database administrators for a long time. As virtualization continues to grow in every aspect of the IT infrastructure, tuning the OS, DB or storage tends to become even more complex.[...]

Working with the CLARiiON system cache

For best performance with most applications, each SP should have its maximum amount of cache memory and you should use the default settings for the cache properties. Analyzer shows how the cache affects the storage system, and lets you tune the cache properties to best suit your application. A storage-system cache has two parts: a read cache and a write cache.[...]
