New physical disks can be added by expansion of a Disk Group (DG) while the unit remains online. During the process of expanding Disk Groups.

De-fragmentation can be selected to move unused capacity to the ending LBA of a Disk Group. De-fragmentation can also be selected at anytime there is unused storage space residing between Logical Disks.

Logical Disk (LD) Online Expansion can increase the capacity of an online LUN, instead of having to create a separate partition for unused capacity or capacity gained from Disk Group Expansion; now your storage can dynamically grow as your demands grow. In the event of overestimating requirements for Logical Disk capacity, shrinking can be used reduce the allocated storage of a Logical Disk.

We provides an Array Recovery Utility (ARU) or technique that can aid a user in the event of multiple drive failures corrupting the RAID array of a Logical Disk and/or volumes. The ARU enables users to recover lost disk members of a Disk Group, and will automatically recover Logical Disks and Volumes.

Array Roaming is applied to whenever the customer would like to move the whole RAID's disks from one controller system to the other without changing its configuration or the working status. The new controller system still can identify and restore all the data from the pervious controller system.

With our new storage products structure, local and global spares can be configured. Local spares will belong to specific Disk Groups and will only replace faulty drives in a specific Disk Group. Meanwhile, Global Spares will replace faulty disk in any available Disk Groups.

A Network Entity is a device or gateway that is accessible from the IP network or it has one or more network portals.

A Network Portal is a part of a network entity that has a TCP/IP network address and may be used by an iSCSI node, a network portal in an initiator is identified by its IP address, a network portal in a target is identified by its IP address and its listening TCP port, and a network portal can be used by one or more iSCSI nodes is a device or gateway that is accessible from the IP network or it has one or more network portals.

An iSCSI Node is a single iSCSI initiator or iSCSI target. There can be one or more iSCSI nodes within a network entity.
