Now we have one big and fast LVM volume made from 4x960GB SSDs disks in a raid0 array, a total of 3839GB.
Here is a tutorial for a MEGARAID LSI Hardware RAID Controller using the storcli utility to increase an existing RAID array with no additional downtime after the drives are added and without moving data or restoring it. As the storage needs increases with the business, additional disks need to be added to the RAID0 array, making it BIGGER and faster… which is really nice… but not very easy and it may be risky if you mess things up.
To achieve this dream the best solution is a RAID0 (stripping) array with super fast SSD’s. BIG Data is the new bacon, but to manage the new BIG data driven businesses we need a lot of storage and better than a lot of storage is a lot of super fast storage ?
