High-end NAS device runs Linux

Jan 27, 2010 — by Eric Brown — from the LinuxDevices Archive — 3 views

Enhance Technology announced an eight-disk, Linux-based network-attached storage (NAS) device, offering up to 16TB of SATA storage. The UltraShare NAS8000-P4 incorporates an Intel Xeon (Nehalem) CPU clocked at 2.0GHz, four gigabit Ethernet ports, and an optional gateway for expanding to up to 176TB.

The UltraShare NAS8000 is aimed at data-intensive applications such as file sharing, fast FTP access (for an ISP), and video archive and retrieval for IP surveillance cameras, says Santa Fe Springs, Calif.-based Enhance Technology. Suitable for both SMB networks and a large corporate IT infrastructure, the device supports file sharing across Linux, Apple OS X, UNIX, and Windows clients, and allows remote access via FTP with encryption, says the company.

The NAS device is said to offer load balancing, fault tolerance, and advanced security features. The device can also synchronize to network directory services including ADS/PDC, NIS, and LDAP, says Enhance Technology.

The UltraShare NAS8000-P4 is powered by an LGA1366-socketed Intel Xeon (Nehalem) CPU, supplied with 3GB of DDR3 memory. The UltraShare NAS8000 incorporates an eight-drive RAID array for up to 16TB of data storage using 2TB SATA hard drives, says Enhance Technology. Data storage volumes can be individually protected via RAID controllers that offer features including RAID-6 and hot-spares, says the company.

Each system can also be expanded via an optional RS16 SS gateway for RAID protected data storage of up to 176TB. The RS16 SS gateway enables the connection of up to five 3U 16-bay "RS16 JS" rackmount storage devices as one single system "without compromising the data transfer performance," claims the company (see diagram below).

The standard P4 version of the NAS8000 offers four gigabit Ethernet ports, but a NAS8000-TG version is available that instead offers a single 10-gigabit Ethernet (10GbE) interface, says the company. The device is said to offer a dual redundant 380 Watt "80-Plus" power supply, and is cooled by four fans that permit operation at up to 95 deg. F. The Linux-based UltraShare N8000 ships with an installation wizard and a graphical user interface (GUI) for local or remote configuration, says Enhance Technology.
