Linux-based home NAS devices use as little as seven Watts

Feb 2, 2011 — by Eric Brown — from the LinuxDevices Archive — 14 views

Qnap Systems announced additions to its Linux-based Turbo NAS family of network attached storage devices for the home/SOHO market. The TS-x12 lineup includes the four-drive (up to 8TB) TS-412, the two-bay TS-212, plus the single-drive TS-112, each providing a 1.2GHz Marvell 6281 processor, 256MB of DDR2 memory, plus gigabit Ethernet and USB connectivity.

Like the four-bay TS-x19P+ NAS devices that Qnap announced in November, the TS-x12 models come in four, two, and one-drive versions, and are said to run on a Marvell system-on-chip (SoC). While the earlier devices ran on a Marvell 6282 processor clocked to 1.6GHz, the TS-x12 use a "brand new" Marvell 6281 clocked to 1.2GHz instead. This appears to be another version of the Marvell Kirkwood design, which also spun off the related Armada 300.

The new TS-x12 models offer slightly scaled down functionality compared to their TS-x19p counterparts, although the two four-bay models appear almost identical. The two-bay and single-bay devices share a physical design that differs from the TS-219P+ and TS-119P+.

All three of the models offer 256MB DDR2 memory and 16MB flash, says Qnap. They all provide varying numbers of 2.5-inch and 3.5-inch SATA II hard drives with up to 2TB per drive bay, the company adds.

Only the four-bay TS-412 provides swappable drive trays. It also supports RAID 0/1/5/6/5+ storage, according to Qnap, while the others offer RAID 0/1.

The TS-412 offers dual gigabit Ethernet ports, as well as four USB 2.0 ports (one front-facing) and dual eSATA ports for storage expansion, says Qnap. The two-bay TS-212 and the single-drive TS-112 drop down to one gigabit Ethernet port and three USB ports, once again, with one port facing front. Neither offers eSATA expansion.

Standard features include LEDs, buttons, an alarm buzzer, and a K-lock security slot, says Qnap. Missing from the new models is the earlier backlit monochrome LCD display.

As befits the lower clock rate, power consumption is lower than with the TS-x19P+ models. The TS-412 consumes 26 Watts in operation, compared to the four bay TS-419P+'s 31 Watts. The TS-212 and TS-112 are said to consume just 13 Watts and seven Watts respectively.

Like the earlier TS-x19P+ models, the TS-x12 models run Qnap's Linux-based NAS firmware 3.3. The software provides automatic backup of all computers on the network, as well as the ability to host websites and record home security surveillance video from IP cameras on the network, says Qnap.

The software also provides a UPnP-compliant media server, and can act as a standalone file server for BT/FTP/HTTP and eMule downloads, says the company. The included TwonkyMedia UPnP server supports media players such as the Sony PS3 and Microsoft Xbox 360 gaming consoles, as well as HD media players compatible with NFS, says Qnap.

In addition, Apple iPod/iPad/iPhone or Android devices can be used to stream music and video or view digital photos stored on the NAS via a Wi-Fi or 3G connection, says the company.

Stated Tony Lu, Product Manager from QNAP. "Home users no longer need to sacrifice performance for lower-cost NAS; and the new TS-x12 series offers advanced features like RAID and iSCSI support, making them an incredible value for the money."

Availability

The TS-x12 series will be available globally starting in February through popular commercial distributors, resellers, and retailers, says Qnap. More information may be found on Qnap's TS-112 page, TS-212 page, and TS-412 page, respectively.
