Pillar’s CEO Mike Workman dropped by our office today, and said that while Pillar retains its earlier reservations about SSDs not being best utilized behind a network loop, the company will support them next year. The systems vendor will not have an exclusive partner for the drives, Workman said, though he mentioned Intel as one supplier.
Pillar’s Axiom arrays separate disk capacity from the storage controller with components called bricks (disk) and slammers (controllers). Workman says the Axiom will support SSDs in the bricks, and the arrays’ QoS features will be updated to support moving workloads to SSDs. This can happen either according to policy or automatically (with prior user approval) when the system is under intense workload.
This is definitely a change in tune, though Workman has always said Pillar’s systems were capable of supporting SSDs and probably would. He just thought network latency was too great, and he hasn’t retreated from that position. “It’s there,” he said. “There’s no way to get around that.”
But Workman says the biggest obstance to SSD now is price. “When we show people how they work, they say, ‘Fine,'” he said. “Then we tell them how much it costs, and that’s when they keel over.”
Despite offering an 80% utilization guarantee earlier this year, Workman said only about 15% of Pillar’s customers are at 80%. But the company hasn’t been paying out lots of guarantee money, either. The details of the offer are vague to begin with: the terms are negotiated on a case by case basis, “to remediate any issue, as well as financial pain.” The terms of the guarantee would have to be negotiated as part of the original sale.
Analysts also said users might be wary of pushing utilization that high given that it requires capacity planning to be precise. “I can’t make [customers] write data to the system,” Workman said. “The guarantee was not that they will but that they can.” He added that the average Pillar customer’s utilization currently is 62%.
