CLARiiON Flare release 29 (04.29.000.5.001) introduce support for several new features as follow: 1) Virtualization-aware Navisphere Manager - Discovery of VMware client always were difficult in earlier release but Flare 29 enables CLARiiON CX4 users and VMware administrators to reduce infrastructure reporting time from hours to minutes. Earlier releases have allowed only a single IP address to be assigned to each iSCSI physical port. With Flare 29, the ability to define multiple virtual iSCSI ports on each physical port has...

Any disk drive from any manufacturer can exhibit sector read errors due to media defects. This is a known and accepted reality in the disk drive industry, particularly with the high recording densities employed by recent products. These media defects only affect the drive’s ability to read data from a specific sector; they do not indicate general unreliability of the disk drive. The disk drives that EMC purchases from its vendors are within specifications for soft media errors according to the vendors as well as EMC’s own Supply...

To setup Replication Manager you must perform the following tasks:1) Verify that your environment has the minimum required storage hardware and that the hardware has a standard CLARiiON configuration.2) Confirm that your Replication Manager hosts (server and clients) are connected to the CLARiiON environment through a LAN connection.3) Zone the fibre switch appropriately (if applicable). The clients must be able to access all storage arrays they are using and the mount hosts must be able to access all storage in the EMC Replication...

The following rules and recommendations CX systems:1) You cannot use any of the disks 000 through 004 (enclosure 0, loop 0, disks 0-4) as a hot spare in a CX-Series system.2) The hardware reserves several gigabytes on each of disks 000 through 004 for the cache vault and internal tables. To conserve disk space, you should avoid binding any other disk into a RAID Group that includes any of these disks. Any disk you include in a RAID Group with a cache disk 000-004 is bound to match the lower unreserved capacity, resulting in...

The following major configuration steps for the storage, server and switches necessary for implementing the CLARiiON.Install Fibre Channel HBAs in all systemsInstall EMC CLARiiON LP8000 port driver ( For Emulex) on all systemConnect each host to both switches ( Broace/Cisco/McData)Connect SP1-A and SP2-A to the first switchConnect SP1-B and SP2-B to the second switchNote:- You can use cross SP connection for HA and connect SPA1 and SPB1 to first switch and SPB2 and SPA2 to the second switch.Install Operating System on windows/solaris/linux/Vmware...

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.Apart from CPU power and memory size, disk subsystem handles the movement of data on the computer system and has a powerful influence on its overall response. Also performance disk layout must also be designed to provide appropriate data protection with overall cost in...

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. The read cache uses a read-ahead mechanism that lets the storage system prefetch data from the disk. Therefore the data will be ready in the cache when the application...
