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
"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.
