SnapServer 7.0 Administrator's Guide
SSH
Short for Secure Shell. A service that provides a remote console for special system
administration and customer support access to the server. SSH is similar to telnet but more
secure, providing strong encryption so that no passwords cross the network in clear text.
SSL
Short for Secure Sockets Layer. A protocol for managing the security of a message sent on
the Internet. It is a type of technology that provides data encryption, server authentication,
message integrity, and client authentication for any TCP/IP connection.
Standalone
A network bonding mode which treats each port as a separate interface. This configuration
should be used only in multihomed environments in which network storage resources must
reside on two separate subnets.
Static IP Address
An IP address defined by the system administrator rather than by an automated system,
such as DHCP. The SnapServer allows administrators to use DHCP-assigned or statically
assigned IP addresses.
Storage Area Network
See SAN.
Stripe
The process of separating data for storage on more than one disk. For example, bit striping
stores bits 0 and 4 of all bytes on disk 1, bits 1 and 5 on disk 2, etc.
Stripe Size
This is the number of data drives multiplied by the chunk size.
Sub-array
In RAID 50 applications, this is the name given to the individual RAID 5 arrays that are
striped together. Each sub-array has one parity drive.
Subnet Mask
A portion of a network that shares a common address component. On TCP/IP networks,
subnets are all devices with IP addresses that have the same prefix.
Target
A target is a device (peripheral) that responds to an operation requested by an initiator
(host system). Although peripherals are generally targets, a peripheral may be required to
act temporarily as an initiator for some commands (for example, SCSI COPY command).
Targets are embedded in iSCSI storage controllers. They are the software that makes the
RAID storage available to host computers, making it appear just like any other sort of disk
drive.
TCP/IP
Short for Transmission Control Protocol/Internet Protocol. The basic protocol used for data
transmission over the Internet.
