QNAP Systems Announces Rack-Mounted Servers

QNAP aims its line of rack-mounted servers at entry-level enterprises, offering features such as a redundant power supply and SMS alerts if drives in the NAS server fail.

NAS server, NVR video surveillance systems and network-based video player manufacturer QNAP Systems expanded its Turbo NAS lineup with a pair of high-performance NAS servers for the corporate and entry-level enterprise market.

The TS-439U-RP and TS-439U-SP models are both four-drive 1U rack-mounted network-attached storage servers with hot-swappable drives that are capable of up to 8TB of total capacity using 2TB drives.

The two models are equipped with a newly designed HDD (hard disk drive) tray for 2.5-inch and 3.5-inch HDD dual support, which QNAP said gives users more choices to deploy the hard drives. The TS-439U-RP and TS-439U-SP feature an Intel Atom 1.6GHz CPU and 1GB DDRII memory, with up to an 87.3MB-per-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 also feature iSCSI Target service with thin provisioning and dual Gigabit LAN ports with port trunking (supporting seven bonding modes) and multi-IP setting.

The TS-439U-RP and TS-439U-SP NAS servers will be available this month and will include a pair of rack slide rail kits for free. The optional redundant power supply for the TS-439U-SP will be available at the time of launching, the company said.

"The TS-439U family reinforces our commitment to our corporate, entry-level enterprise and data center customers," said QNAP CEO Meiji Chang. "While our competition tries to sell business customers a consumer-level NAS server, QNAP delivers true business-class NAS servers with best-in-class performance and features, and rock-steady reliability."

The TS-439U-RP and TS-439U-SP come standard with Version 3 of QNAP's NAS management software, embedded as firmware, and adds new features including virtual disk drive support (up to eight virtual disks via iSCSI expansion over the network) and exclusive QNAP RAID recovery that can recover an inactive RAID 1, 5 or 6 due to unintentional removal of drives. Network discovery services have also been enhanced with Bonjour support, offering zero-configuration networking for HTTP, SAMBA, FTP, AFP and SSH based networks, and full UPnP (media sharing) support.

Other new features of Version 3 include EXT4 support for very large volumes and file sizes, SNMP support, and bitmap support for faster rebuilding of RAID volume after a crash or adding/removing a drive. Version 3 also includes an all-new, user-friendly AJAX-based Web interface compatible with popular Web browsers. In addition, QNAP NAS servers feature hot-swap removable cartridge drives throughout the entire lineup, and offer features including iSCSI and dual Gigabit LAN ports with failover, load balancing and multi-IP setting capabilities for all Intel-based models.
