Recently, many vendors announced the availability of large SSDs. It’s not extremely exciting – it’s just a larger storage medium. Sure, it’s really advanced 3D NAND, it’s fast and ultra-reliable, and will allow some nicely dense configurations at a reduced $/GB. Another day in Enterprise Storage Land.
But, ultimately, that’s how drives roll – they get bigger. And in the case of SSD, the roadmaps seem extremely aggressive regarding capacities, with 100TB per device coming.
Then I realized that several vendors don’t have large SSD capacities available.
But why? Why ignore such a seemingly easy and hugely cost-effective way to increase density?
In this post I will attempt to explain why certain architectural decisions may lead to inflexible design constructs that can have long-term flexibility and scalability ramifications.

It’s been a while since our last SPC-1 benchmark submission with high-end systems in 2012. Since then we launched all new systems, and went from ONTAP 8.1 to ONTAP 8.3, big jumps in both hardware and software.
In 2012 we posted an SPC-1 result with a 6-node FAS6240 cluster – not our biggest system at the time but we felt it was more representative of a realistic solution and used a hybrid configuration (spinning disks boosted by flash caching technology). It still got the best overall balance of low latency (Average Response Time or ART in SPC-1 parlance, to be used from now on), high SPC-1 IOPS, price, scalability, data resiliency and functionality compared to all other spinning disk systems at the time.
Today (April 22, 2015) we published SPC-1 results with an 8-node all-flash high-end FAS8080 cluster to illustrate the performance of the largest current NetApp FAS systems in this industry-standard benchmark.
