QNAP Systems (http://www.qnap.com) has expanded its Turbo NAS line-up
with a pair of new NAS servers for the corporate and entry-level
enterprise market. The new TS-439U-RP and TS-439U-SP models are both
4-drive, 1U rack mounted NAS servers with hot-swappable drives that
are capable of up to 8TB total capacity using 2TB drives.

The newly-designed HDD tray for 2.5-inch and 3.5-inch HDD dual
support is also equipped in these two models, which gives users more
choices to deploy the hard drives. The TS-439U-RP and TS-439U-SP
feature Intel Atom 1.6GHz CPU and 1GB DDRII memory, making them
capable of up to 87.3MB/second transfer rate for an FTP read with
RAID 5 enabled.

Both models can be configured for RAID 0/1/5/6/5+ spare, and JBOD
with online RAID capacity expansion and RAID level migration. Both
models feature iSCSI Target service with Thin Provisioning and dual
Gigabit LAN ports with port trunking (support for seven bonding
modes) and multi-IP setting.

The primary difference between the TS-439U-RP and TS-439U-SP is the
RP model includes a redundant power supply that will automatically
kick in if the other fails. The SP model includes a single power
supply, but is upgradeable with an optional redundant power supply
that can be installed without powering down the unit.

The TS-439U-RP and TS-439U-SP arecompatible with Mac, Windows, Linux,
and Unix networks and sport features such as AES 256-bit volume-based
encryption, policy-based IP blocking, secure FTP, encrypted remote
replication for backing up the NAS server to another NAS server over
the network, email or SMS alerts if drives in the NAS server fail or
are about to fail, and much more.

The TS-439U-RP and TS-439U-SP NAS servers will be available later
this month. All shipping package will include a pair of rack slide
rail kit for free. The optional redundant power supply for
