Tegile Systems today introduced a new flagship high-density hybrid array with a flexible mix of solid-state drives and spinning disk, along with a new all-flash array that can scale to 336 TB of raw capacity.
Tegile began selling its flash systems in 2012. It claims more than 500 customers, mostly for its hybrid arrays. Its lone flash array, until now, was the HA2800, which supports only 4.4 TB of raw flash. The flash in the HA2800 is used for caching rather than a storage tier, and the system scales out by adding hard disk drive (HDD) shelves rather than flash. The new T3800 is a storage tier for low-latency, business-critical applications, such as OLTP or data analytics. It scales by adding solid-state drives (SSDs) rather than HDDs, and Tegile said it can store 1.6 PB of usable capacity with 5-1 data reduction from its inline deduplication and inline compression.
The new Tegile IntelliFlash T3400 hybrid system, targeted at virtualized workloads, can hold 22 TB of raw flash in a 2u box and 312 TB of raw capacity in a 10-rack unit with expansion shelves. Tegile said a fully loaded T3400 can perform at 250,000 IOPS with a 10 PB write endurance per SSD. Perhaps the biggest selling point is the per-gigabyte price point for SSD and HDD usage.
"If you load it up with spinning disk, you can get 60 cents per gigabyte, and if you load it up with all flash, using dedupe and compression, it costs $1.30 per gigabyte," said Rob Commins, Tegile's vice president of marketing. "This is a good platform for administrators that deal with mixed workloads that change over time."
Tegile's T3400 hybrid system is flexible, so customers can choose any ratio of SSD and HDD. Caching software moves cold data from flash to spinning disk, which helps increase performance. The array uses 2.2 TB of DRAM for its metadata engine, where deduplication, compression, RAID calculation and snapshots are done.
"[DRAM] does all the data management functions that consume a lot of resources, especially on spinning disk," Commins said. "We do the entire math in DRAM and flash. The cache optimization masks the performance limitations of spinning disk. Deduplication is actually a performance enhancer rather than a drag on the performance configurations.
"It's all built into the base configuration, so essentially there is no software tax."
T3800 a 'real high-density' all-flash array
The new all-flash T3800 stores 44 TB of raw capacity in a 2U box, 336 TB of raw storage in a 10-rack unit, and achieves up to 360,000 IOPS with 10 PB write endurance per SSD.
"An all-flash array with 336 terabytes of raw capacity in a 10-unit footprint is a real high-density system," said Jim Bagley, senior analyst at Storage Strategies Now. "They are advertising a five-times data reduction level. At that rate, the per-gigabyte cost is around a dollar. That is probably half of what the competition offers."
The T3400 and T3800 systems will be available this month.
