AJ424-6G provides flexible, reliable and efficient storage

The JBOD disk array AJ424-6G provides a simple and easy way to dramatically gros online disk capacity to meet exponetial data growth rates. It enables massive data capacity applications, at a price/performance point per Terabyte (TB) that meets any business requirements. Zstor offers low-cost, high-capacity, high-performance disk drives (HDDs) and ultra-high-performance solid-state drives (SSDs) configuration options that is optimized in capacity, performance or versatility. Zstor disk are cost effective solutions meeting meeting customer's price point.

ideal in windows server cluster environment

JBODs designed, equipped and configures by Zstor fits ideal as shared storage in Windows Server 2012 R2 cluster environement. Two nodes, operating under Windows Server 2012 R2 share one or more attached JBODs from Zstor's AJ-series. Via high performing SAS interfaces with up to 12 Gb/s data transfer secures a perfect performance to the attached servers. Robust design of chassis and hot-swappable drive carrier, combined with proven SAS I/O modules grant the access to a huge number of hard disk drives and/or IOP performing solid state disks.

"Storage Spaces" realized as it‘s best

Microsoft Windows Server 2012 R2 needs a high speed access to its storage. Due to the functionality of Storage Spaces there is a just a need for a "Bunch of Disks" (JBOD). Storage Spaces manages the attached hard disk drives as Software Defined Storage and offers storage pools, data reliability, deduplication, file sharing (NFSv4, CIFS), iSCSI targets and much more, inculde SMB 3.0 support. Zstor tested, configured and certified JBODs within Microsoft's certification process for use with Storage Spaces in Windows Server 2012. 

Cost effective and flexible use

JBOD technology itself is a proven way to serve native disk drive capacities to a server or cluster. Zstor AJ series uses latest SAS technology with up to 12 Gb/s data transfer even internally to each attached drive as well as externally to hosts. The complete design is developed with hot-swap drive carrier, power supplies and I/O modules.
