QNAP Systems, a manufacturer of NAS servers, NVR video surveillance systems, and network-based video players has expanded its Turbo NAS lineup with two new mid-range NAS servers targeted at SMB and corporate customers.

According to QNAP, the new TS-239 Pro II (2-drive model) and TS-439 Pro II (4-drive model) incorporate the new Intel Atom D410 single-core processor, which delivers up to 8TB of networked storage coupled with the business- essential features of QNAP’s Business Series NAS servers.

The TS-239 Pro II and TS-439 Pro II NAS servers are compatible with VMware’s vSphere4 (ESX 4.0) virtualization platform, suitable for departmental file sharing, storage, server applications in the office environment, the company said.

The company said that the new NAS servers ship with new version 3.2 of the QNAP NAS management software that supports features such as iSCSI service, SPC-3 persistent reservation for clustering in VMware and Windows Server 2008. The Web File Manager 2 features an entirely redesigned user interface and functionality for improved file sharing and management. WebDAV is also available for users to share, access, and edit files over HTTP and HTTPS.

Laurent Cheng, product manager of QNAP Systems, said: QNAP’s new TS-239 Pro II and TS-439 Pro II models fill an important niche between our ultra high performance Business Series models and our lower performance models. These two new models offer the horsepower of the single-core Intel Atom D410 CPU with all the business applications found in our Business Series at price points that are attractive to SMB and corporate customers.

QNAP Turbo NAS servers are available in 1, 2, 4, 5, 6 and 8-bay tower and rack mount configurations to fit consumer’s needs, including small/medium business, workgroups, and entry-level enterprise networks. Most QNAP NAS servers feature hot-swap removable cartridge drives, and offer features including virtual disk, and dual gigabit LAN ports with fail-over, load-balancing and multi-IP setting capabilities for all Intel-based models.
