EMC Storage Product Knowledge Sharing

I have discussed about lab exercise for Storage Administration purpose, Now, Lets talk about something technical. You understand that we can create Raid 5 protected LUN means we will use striping. So, How will you calculate stripe size of LUN.Before calculating the stripe size of data in Clariion , we have discussed about how many disks make up the Raid Group, as well as the Raid Type.I have two examples of Stripe Size of a LUN. The above...

Very simply, RAID striping is a means of improving the performance of large storage systems. For most normal PCs or laptops, files are stored in their entirety on a single disk drive, so a file must be read from start to finish and passed to the host system. With large storage arrays, disks are often organized into RAID groups that can enhance performance and protect data against disk failures. Striping is actually RAID-0; a technique that breaks up a file and interleaves its contents across all of the disks in the RAID group....
