The sTec s3000 comes in a minimum high-availability configuration of two storage heads and two storage shelves, said Zack Mihalis, sTec's vice president of product management and marketing.
Each head includes two 8-core Intel Xeon E5-2680 processors, 128 GB of memory, dual-mirrored boot drives, four Gbit Ethernet ports and up to six 10-GbE ports. Each shelf includes eight to 48 SSDs for a total capacity of up to 96 TB of SSD storage per node.
The sTec s3000 scales to up to eight nodes. Mihalis said.
The initial configuration of two head units and two storage shelves provides an optimized high-availability solution, he said. "It's the optimal configuration for performance, with no bottlenecks," he said. "And it's optimized for reliability. You can go to up to eight of these nodes. But, some customers might start with one head and one shelf with a minimum of eight SSDs."
sTec's Zadeh said the limit of 48 SSDs per node has to do with ensuring maximum performance.
"When you get over 48 SSDs, the bottleneck becomes the compute head and the backplane of the system," he said. "And you can add more shelves to a head, but you just get more capacity, not necessarily more performance."
With 48 SSDs in a shelf, the sTec s3000 offers 340,000 4k-random-read IOPS and 290,000 4k-random-write IOPS in an iSCSI configuration, or 1.2 million 4k-random-read IOPs and 600,000 4k-random-write IOPS in as SMB3.0 (server message block) configuration, Zadeh said.
"These numbers are not reading from cache," he said. "They're reading from the SSDs. This is four times the performance of the highest-end tier-one solutions costing $1 million and built in boxes the size of two or four refrigerators."
The sTec s3000 is available starting this week with a base price of around $70,000 for one head and eight 800-Gbyte SSDs.
