TABLE 7-2. Frequently Asked Questions.
What is the proper placement of my | The MV 4105 can be operated in a tower configuration only. |
MediaVault? | Whenever possible, do not place the unit near the floor, as it |
| |
| will pick up more dust. |
|
|
What are typical | The internal data rate ranges is 500MB/sec. |
| Externally, you should see between |
| under ideal conditions. In RAID 3, this rate drops by about |
| |
|
|
What is striping? | Striping is a technique where different parts, called sectors, of |
| different disk drives are used alternately in sequence. |
| This is done for several possible reasons: a) Gaining |
| performance; b) Increasing reliability; or c) Increasing |
| capacity. |
|
|
What is spanning/concatenation? | This is a technique where hard disk drives are used |
| end, i.e. where one fills up the data continues on to the next. |
| This is strictly done for capacity, and has no gains in either |
| speed or reliability. |
|
|
What is mirroring? | Mirroring is where data, when written, is written to two differ- |
| ent disks or sets of disks |
| This offers reliability, at the cost of capacity and speed. |
|
|
What is RAID 0? | In RAID 0, the disk drives are striped with corresponding |
| sectors of other drives, called strips, sequentially. |
| Data written goes to sector 1 of drive 1, then sector 1 of drive |
| 2, and so on. RAID 0 sacrifices data protection to gain |
| capacity and performance. |
| To do RAID 0 requires a minimum of 2 disk drives. The |
| MV 4105 uses 5 disk drive modules. |
