The EliteNAS EN424L+BXE is a comprehensive feature-dense 4U 24-bay 64-bit NAS + iSCSI rackmount with a 4.8GT/s Quick Path Interconnect Intel Westmere Xeon Quad-Core processor and 4GB DDR-3 ECC memory. The EN424L+BXE is a performance tuned NAS+iSCSI server designed with hardware RAID protection and dual Gigabit Ethernet, capable of unlimited clients with network share, and supports in IP SAN storage. The built-in SAS expander feature allows expansion of up to 7 additional EliteSTOR SAS Expander JBOD storage units, up to a maximum of 120 drives, making a total of 360TB total storage in a network sharing or iSCSI environment. With 72TB in a single rackmount, the EN424L+BXE is capable of fulfillng the most demanding storage needs.

Dual Gigabit and RAID Hard Drives Protection
EliteNAS is built with simple setup and maintenance features. An installation wizard for easy implementation, convenience web-based management for local or remote configuration, dual 10/100/1000 network support for teaming or redundant networking, and hardware RAID support for your data storage make EliteNAS a simple trouble free unit. Dedicated 1200MHz processor RAID engines support online migration and expansion while offloading complex RAID calculations to improve overall performance. 

SAS Expander support for storage expansion
Supported SAS expander allows connections to 7 additonal SAS expander JBODs (EliteSTOR ES208X+BE, ES316X+B or ES424X+B), or up to 120 total drives for 360TB total storage. (Optional Gateway License Required)

Support SAS or SATA hard drives
Supports both high performance SAS hard drives or high capacity, low cost SATA hard drives.

Hardware RAID support up to 60
Supports latest RAID levels, including RAID 0, 1, 3, 5, 6, 10, 30, 50 and 60 for advanced data protection in large numbers of hard drive deployments.

Feature Rich Network Storage -  Build-in Snapshot, Folder Replication and iSCSI
In comparison to other NAS units in the market, EliteNAS is bundled with many additional advanced features at no additional charge. iSCSI target support for iSCSI applications, iSCSI initiator support for easy future expansion, NAS to NAS folder replication, scheduled or on-demand volume snapshot, and local tape backup support are just a few of the many features this product offers.

iSCSI Support for VMware and Microsoft Hyper-V
To take advantage of centralized storage for all virtual machines in VMware ESX or Vsphere, the EN424L+BXE can be used as a focal storage point for the VMWare ESX or ESXi server hosting multiple virtual machines. Utilizing the EN424L+BXE as an iSCSI target storage system for the VMware ESX/ESXi server, the EN424L+BXE is ready for your VMware storage virtualization needs.

Microsoft Hyper-V virtualization environment is also supported. With the support of SPC-3, iSCSI can be used in Microsoft Windows Server 2008 or Windows Server 2008 R2 clustering environment for high-availability applications.

Optional NAS to NAS Automatic Server Failover and Mirroring
Server Failover and Mirroring (SFM) is an optional feature used to bind two EliteNAS servers as one so that data is written to both systems simultaneously. At the same time, automatic fail-over will be supported in case of primary system failure. Clients attached to the primary NAS server can be serviced by the secondary server and will not notice the fail-over process when the secondary EliteNAS takes over to provide high avaliablity redundancy.

10Gb Network Interface Controller Option for 10GbE Network Support
10Gb Ethernet network Interface controller card is supported for 10Gb Networking. With 10 times faster bandwidth compared to 10/100/1000 Gigabit Ethernet, the 10Gb network interface controller provides high performance solutions when needed. XFP, SFP+ and CX4 connectors are avaliable.
