SmartExtend – Add More NAS Capacity
5.5 SmartExtend – Add More NAS Capacity
The SmartExtend feature can add NAS capacity over LAN. A
SmartExtend initiator can connect up to 10 SmartExtend target
volumes via the Giga- or Fast-Ethernet ports. A target volume
can provide up to 2TB of capacity, so it can increase NAS
capacity by as much as 20TB!
