RAID Level 5 is a type of RAID that uses block-level striping (spreading out the blocks of each file across multiple disk drives) and block-interleaved distributed parity to spread the redundant parity information used to achieve fault tolerance across all the disks in the array. If any disk fails, the distributed parity data are used to compute the contents of the "virtual" (failed) disk. An advantage of RAID 5 is that there is no single dedicated parity disk causing a write bottleneck.

RAID 1" refers to a "Redundant Array of Inexpensive (or Independent) Disks" that have been established in a Level 1, or mirrored, drive set. A RAID 1 volume is a set of disk drives that are configured for data to be written to 2 volumes simultaneously. This configuration provides complete data redundancy in the event of a drive failure.

A Hot Spare Disk Cartridge is an additional Disk Cartridge installed in a 3U Server that is immediately available as a replacement if a hard disk drive fails. If an active drive fails, the Server continues to operate, no content or user-entered data is lost, and information that was stored on the failed drive is automatically restored to the hot spare. This eliminates the need for an urgent service call and provides peace of mind in marine and other remote installations. See similar questions...

RAID 1 has better performance compared to RAID 5, in particular, the write performance is much better. As web and email servers does a lot of writes, to log files, email spools etc, RAID 5 is not suitable for the server. In terms of redundancy, RAID 5 has 1 parity drive in an array (of possibly 7 drives). With a failure of 1 drive, the array performance is badly degraded. This may lead to much higher IO waits, and the server will be unresponsive. See similar questions...

Many times information is still recoverable, depending on how the drives were re-formatted. A high-level re-format (using Windows, for example), will create what will appear to be a new "clean" volume - but the original data will still be on the disk in the "free and available" space. A low-level format routine (as performed using the controller software) will overwrite every sector, and in the process destroys the original data. Perhaps, but it wouldn't be the safest approach.

A minimum of at least two (2) hard drives are required to create and maintain a RAID 1 volume. Unlike some other RAID configurations, RAID 1 volumes require an even number of drives to be used. See similar questions...

Yes. As long as the volume is recognized by Windows as a disk device, Casper Tech Edition will support it. Yes. Casper Tech Edition is device independent. As long as the drives are recognized by Windows, Casper Tech Edition will support them. Before cloning a disk for use on another machine, the disk should be prepared for the cloning process by running Microsoft's Sysprep utility. For more information about this utility see Sysprep Technical Reference. See similar questions...

RAID Level 1 is a disaster recovery method where one hard drive mirrors a second one. In the event that one of your drives fails, the other will immediately continue to serve data. An additional feature with RAID is that, if one drive is overtaxed, the overflow requests will be handled by the second drive. RAID 1 requires two drives, but you will lose the disk space of one of the drives. See similar questions...

RAID 1 is a particular type of RAID technology which ensures that all data is duplicated on pairs of disks simultaneously. This ensures that in the event of a hard drive failure, the server can switch to the other disk with no interruption in service. Also, if multiple requests for the same data are made, demand can be distributed between two disk copies therefore decreasing response time for data access. See similar questions...

Absolutely. We can provide software RAID1 for your VPS; and additional harddisks if required for your backups. See similar questions...

Dismount the disk, and mount it privately. If the disk is mounted by more than one node in an OpenVMS Cluster, dismount it from all other nodes. If this disk is an OpenVMS system disk, shut down all other nodes that are bootstrapped from this disk. On OpenVMS V6. See similar questions...
