What is 3DES?

July 9th, 2009

3DES, also referred to as triple DES, is a mode of the Data Encryption Standard (DES) encryption algorithm. 3DES uses three 64-bit keys to encrypt data thrice. Primarily, it encrypts data with a 64-bit key. Then, the output data is again encrypted with the second 64-bit key. Finally, the third 64-bit key is used for encryption. DES uses the block cipher method to break a data file into 64-bit blocks, which are then encrypted.

What is a hot spare disk?

July 8th, 2009

A hot spare disk is a hard disk drive that is flagged for use in case another drive in the RAID array fails. If a hot spare disk is configured with a RAID array, and a disk in the RAID fails, the hot spare disk is immediately available for the RAID to start rebuilding the RAID data. As soon as the rebuild is completed, the RAID array becomes fully functional without affecting the performance. All the RAIDS (0, 1, 3, 5, etc.) support hot spare disks.
