iXsystems TrueNAS Arrays Improve Scalability to Almost 5PB per Rack

TrueNAS Z35 Arrays Increase Capacity 2.5x Times With New E60 Expansion Shelf

SAN JOSE, CA--(Marketwired - November 24, 2015) - iXsystems, the industry leader in storage and servers driven by Open Source, officially announced the TrueNAS E60 expansion shelf. Adding a TrueNAS E60 to a TrueNAS Z35 enables scaling to 3.84PB, a 150% improvement in addressable capacity, and does so in only 35U of rack space, less than half the rack space of other enterprise storage vendors. A density of over 100TB per rack unit allows for a deployment of almost 5PB in a 48U rack. Unlike legacy and flash-only storage architectures and systems that are deployed to support individual applications, scaling to almost 4PB enables users to reduce storage dedicated to an individual application by centralizing their storage on a single TrueNAS Z35. A fully-populated TrueNAS Z35 is priced at less than half of other storage vendors' solutions, like EMC and NetApp, while other storage vendors like Dell, Nimble Storage and Tintri can't achieve the same scale. TrueNAS also delivers this impressive capacity while consuming 40% less data center floor space than the competition.

Traditionally, dense storage expansion shelves can create I/O bottlenecks in a storage array, but TrueNAS optimizes I/O performance with TrueCache™, a combination of RAM and nonvolatile flash with its high-density spinning disks, providing a cache-first storage approach that delivers blistering performance from flash memory for your most frequently accessed data on SAN and/or NAS. TrueNAS also safeguards data from corruption and has built-in local and remote replication, intelligent inline compression/deduplication, and encryption. It also includes 24/7 US-based technical support.

TrueNAS Adaptive Compression (TAC) pushes the usable capacity of the TrueNAS Z35 even further, stretching effective capacity beyond 10PB in some cases. TAC is in-line and eliminates the redundancies in stored data, compresses what it can, and skips over any already compressed data. It reduces the size of I/Os before they reach storage media, which also increases I/O performance.

"With such a significant improvement in the maximum capacity of a single TrueNAS Z35, allowing nearly 4PB in a single rack with room to spare, we can now add 'incredible rack density and scalability' to the long list of features that already make TrueNAS the best value in storage", said Brett Davis, Executive Vice-President of iXsystems.
