advantages when several peripherals need to be connected to the bus. One
advantage is that SCSI allows for up to 15 peripherals to be connected to each
channel, and since most SCSI controllers have two channels, up to 30 peripherals
can be attached. Conversely, with most motherboards, IDE only supports up to two
peripherals. In addition, SCSI is quite a bit faster than IDE, especially when
multiple peripherals are attached. Storageflex supports both the IDE and the SCSI
interfaces.
Snapshot
It is a "frozen" image of a volume and it represents the status of a volume at some
given instance. It remains unchanged in case you're changing the original image.
This image can be used for backups.

Status
An administrator can view status information about the Appliance through
ApplianceView. The administrator can view available and used space on each
partition of the appliance, user connections to the appliance, appliance status, and
appliance name.
Software RAID Appliance
An Appliance that uses a Redundant Array of Independent Disks (RAID) as the
storage medium. In a Software RAID appliance the disk array is controlled and
maintained by Storageflex software, so that no RAID controller card is necessary.
All information that is stored on the appliance will be contained in the RAID.
Storageflex offers Software RAID levels 0, 1, and 5.
Subnet Mask
The subnet mask is the number (formatted similar to an IP address) that is used to
define a sub-network so that IP addresses can be shared on a Local Area Network.
If the Server Appliance has a static IP address, the Subnet Mask needs to be entered
in ApplianceView.
