I have a client that purchased 3 Dell PowerEdge 2950 Servers. 2 with 4 - 300GB SAS Drives and one with 6 - 300GB SAS drives. &nbsp;He had all of them configured for RAID 0 and now that he sees the error of his ways he wants to switch them to RAID 5. &nbsp;What is the easiest/safest (data safety is the highest requirement) to make the switch? &nbsp;The only thing i could come up with is back up all the servers, then make a Ghost image of the servers. Reconfigure the RAID, and drop the Ghost image back on the new array having the backup as a secondary restore point just in case something gets corrupted in the ghost image. &nbsp;Any other suggestions?

Switch from RAID 0 to RAID 5

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
