JStor NAS - Network Attached Storage appliance


Key Benefits
  • Very Affordable & Scalable NAS solution - from few hundred Gigabytes to multiple Terabytes.
  • Very Flexible - Used in connection with JStor RAID it gives you the flexibility to start with a direct-attached RAID array, then Upgrade to a NAS device. Or to "detach" some JStor RAID arrays from the JStor NAS to be used independently as server attached storage.
  • Can attach multiple JStor RAID arrays to JStor NAS engine.
  • Works with JStor IDE/S-ATA units as well as JStor SCSI units.
  • Provides Hardware NAS engine and Hardware RAID array for blazingly fast performance.

The JStor NAS Storage Appliance provides an affordable, scalable storage option for your network. This high-performance, LAN-attached device is designed to provide shared storage to both clients and servers in Windows, UNIX, Apple Macintosh or mixed environments. Engineered to meet stringent demands for continuous availability, JStor NAS features a brand-new 64-bit RISC processor for blazingly fast parity calculation and I/O operations, completely cableless backplane-based design, and storage capacities reaching 14TB starting at a 4U enclosure.

Low service and integration costs are assured by the JStor cableless design, two redundant hot-swappable power supplies, turbo cooling fans, and embedded hardware RAID controller. Three year warranty comes standard with every NAS and covers all components.

JStor NAS Storage Appliance delivers multi-protocol support (Windows CFS, NFS, HTTP, FTP and Novell IPX)that eliminates the need to have separate servers for each supported protocol, further enhancing their ability to consolidate storage from multiple general-purpose servers.

JStor NAS is designed to be easy to use and install and includes robust capabilities designed to improve storage reliability and availability helping to ensure your business applications are available when you need them.
