QNAP TS-459U-RP Turbo NAS - NAS server - 4 bays - rack-mountable - SATA 3Gb/s - HDD - RAID 0, 1, 5, 6, JBOD, 5 hot spare - RAM 1 GB - USB 2.0 / Gigabit Ethernet / eSATA-300 - iSCSI support - 1U

The most affordable and flexible virtualization solution The TS-459U-RP is certified as compatible with VMware vSphere4 virtualization platform.

The NAS can be utilized as the networked shared storage of VMware virtualization environments and Windows cluster servers.

Comparing with traditional SAN, the Turbo NAS is a competitive alternative with much lower setup and maintenance costs in an IP SAN.

Designed for virtualized and clustered environments Comparing with the high cost of fiber channel SAN, the Turbo NAS is an affordable system that can be deployed as a storage center for virtualized and clustered server environments, such as VMware and Microsoft Windows Failover Cluster.

Virtual Disk Drive (VDD) adds flexibility to storage expansion along with ease of management The unique "Virtual Disk Drive" adds flexibility to expand the capacity of NAS.

By using the built- in iSCSI initiator, the NAS can connect to other iSCSI targets on the network and turn them into virtual disks, which become multiple single volumes on the NAS.

Up to 8 virtual disks can be stacked.

The NAS serves as the storage stack chaining master.

The user only needs to connect to this single entry (QNAP NAS) and is able to reach and use all the iSCSI LUN on the network.

Redundant power supply The TS-459U-RP is equipped with two power supply units, each of which is capable of supplying the power for the entire NAS independently.

If one of the units fails, the other one will take over to supply the power to ensure continuous operation of the NAS.

You can replace the failed power supply unit without turning off the server.
