storage server Storage server software maintains the customer's data. It reads to and writes from disks in response to customer reads and writes of SANiQ volumes. stripe Striped data is stored across all disks in the array, which increases performance but does not provide fault tolerance. synchronize The process of copying the most recent snapshot from the primary volume to a new remote snapshot. On failback, synchronization is the process of copying the most recent remote snapshot back to the primary volume. The CMC displays the progress of this synchronization. Also, you can manually synchronize if necessary to include data that is on the remote volume but not the primary. target secret Target secret is used in both 1-way and 2-way CHAP when the target (volume) challenges the iSCSI initiator. temporary space Temporary space is created when a snapshot is mounted for use by applications and operating systems that need to write to the snapshot when they access it. Temporary space can be converted to a volume using the SmartClone process. thin provisioning Thin provisioning reserves less space on the SAN than is presented to application servers. Trap Community String The Trap Community String is used for client-side authentication when using SNMP. unicast Communication between a single sender and a single receiver over a network. VIP virtual IP address virtual IP address A highly available address that ensures that if a storage system in a cluster becomes unavailable, servers can still access the volume through the other storage systems in the cluster. virtual machine A virtual storage appliance that provides one or more simultaneous storage environments in which SAN/iQ may execute as though they were running on the bare iron. virtual manager A manager that is added to a management group but is not started on a storage system until it is needed to regain quorum. volume A logical entity that is made up of storage on one or more storage systems. It can be used as raw data storage or it can be formatted with a file system and used by a host or file server. volume set Two or more volumes used by an application. For example, you may set up Exchange to use two volumes to support a StorageGroup: one for mailbox data and one for logs. Those two volumes make a volume set. volume lists For release 7.0 and earlier, provide the link between designated volumes and the authentication groups that can access those volumes. Not used in release 8.0 and later. volume size The size of the virtual device communicated to the operating system and the applications.
