iXsystems, a provider of open source-powered storage and servers, has unveiled its TrueNAS E16F All-Flash expansion shelf for the TrueNAS Z50 TrueFlash all-flash storage array. The TrueNAS Z50 is designed and developed to make optimal use of the intelligent compression and optional deduplication features provided in TrueNAS.
The maximum SSD capacity was doubled from 1.92GB to 3.84GB and up to four TrueNAS E16F expansion shelves can be added to a TrueNAS Z50 TrueFlash. These improvements increase the maximum capacity of the Z50 TrueFlash ten-fold to 300TB. This would make the TrueFlash ideal for customers that want to migrate multiple performance sensitive applications from a legacy or hybrid storage array to an all-flash storage array or are implementing an all-flash virtualized data center.
The Z50 TrueFlash is designed for the high storage performance requirements of heterogeneous VMware environments. An equivalently performing spinning disk solution would cost significantly more, with hundreds of drives, vastly greater complexity, maintenance, power, and rack space. Using four E16F shelves, the TrueNAS Z50 can scale to over 300TB raw in 15U of rack space. The intelligent block-level compression and deduplication can increase this up to ten times, addressing over 8.4 PB in a 42U rack.
TrueNAS uses TrueCache, which leverages system RAM and flash for “blazing performance and allows for seamless growth from zero to four expansion shelves with under 3% throughput impact.” With all-flash systems, the important factor is storage latency as well as throughput. As more E16F storage shelves are added, TrueCache would provide the services to maintain the sub-millisecond latency expected from an all-flash system as well as sustain the same throughput always possible with the TrueNAS Z50 TrueFlash Storage System.
“Increasing the capacity of the Z50 TrueFlash enables customers to consolidate multiple high-performance applications onto a single TrueNAS Z50 TrueFlash array, instead of dedicating an all-flash array to each application,” said Gary Archer, Director of Storage Marketing for iXsystems. “We can now add ‘incredible all-flash density and scalability’ to the long list of features that makes TrueNAS the best value in storage at VMworld.”
TrueCache would optimize the performance of TrueNAS by combining RAM and flash, eliminating I/O bottlenecks and allowing sustained optimal performance while hot-attaching E16F shelves to the TrueNAS Z50 TrueFlash system. VMware environments backed by TrueFlash would be able to rely on the consistent sub-millisecond performance of flash storage, even when accessing cold data. Additionally, TrueNAS would safeguard data from corruption, has built-in local and remote bi-directional replication, encryption, and data compression.
