QNAP Systems, Inc., a leading manufacturer of world class NAS servers, NVR Video Surveillance Systems, and Network-based Video Players today expanded their popular Business Series Turbo NAS lineup with two new 1U rack-mounted, 4-drive models, the TS-459U-RP and TS-459U-SP. These new models, with up to 8TB of storage (using 2TB hard drives), have been certified as compatible with VMware's vSphere4 (ESX 4.0) virtualization platform, ideal for departmental file sharing, storage, and advanced server applications in the office environment. VMware's vSphere is the industry's first cloud operating system that offers a way to reduce IT costs and increase responsiveness. Shared networked storage is an essential component of a cloud computing infrastructure. The TS-459U-RP and TS-459U-SP incorporate the Intel Atom D-510 1.66Ghz dual-core processor and feature 1GB of DDRII RAM , delivering exceptional performance and high reliability for multiple concurrent tasks and intensive data transfer with lower power consumption. Businesses of all sizes are able to enjoy the interoperability between VMware virtual machines and QNAP high performance storage to take the advantages of VMware cloud computing environments. "QNAP's commitment to delivering SMB, Corporate, and entry-level Enterprise customers exactly what they need, and nothing they do not shine through with the TS-459U-SP and TS-459U-RP models" said Laurent Cheng, Product Manager of QNAP Systems, Inc. "These new Business Series models provide businesses of all sizes a solid foundation for their network storage needs and a host of business-critical applications." Mr. Cheng added. The new models are differentiated with the TS-459U-RP containing redundant power supplies. Should one power supply fail, the other will continue to supply the power for the entire system and alert the administrator via email or SMS to the failure. The TS-459U-SP contains a single power supply, and can be upgraded to the –RP configuration with installation of a second power supply module, sold separately. Both models support RAID 0/1/5/5+ hot spare/6, and JBOD, with online RAID capacity expansion, online RAID level migration and RAID recovery. Both models also feature 256-bit AES volume level encryption for maximum data security. The TS-459U-RP and TS-459U-SP models feature 5 USB ports (1 front panel & 4 real panel) and 2 e-SATA ports for storage expansion and printer sharing. Both models support advanced features including DOM architecture with fail-safe dual OS, scheduled power on/off, Wake on LAN, and HDD S.M.A.R.T. The new models come pre-installed with version 3.2 of the QNAP NAS management software which supports lots of class-leading new features such as iSCSI service; supports SPC-3 Persistent Reservation for clustering in VMware and Hyper-V clusters in Windows Server 2008. MPIO and MC/S are also supported. As well as new DFS support (Shared Folder Aggregation), import of user-list, the next-generation Internet Protocol, IPv6, has been incorporated for future networking evolution. QNAP's 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 collaboratively share, access, and edit files over HTTP and HTTPS. Additionally, Apple Time Machine backups are now supported. Availability The new TS-459U-RP and TS-459U-SP Business Series Turbo NAS servers are available from March through QNAP global commercial distributors, resellers, and retailers.
