Welcome to our fourth episode. In this year end wrap-up Howard and Ray talk about the three trends that have emerged over the last year or so which are impacting the storage industry in a big way and will continue to affect the industry in the the years to come.
First up is scale-out storage. Howard and Ray were part of Storage Field Day 4 (SFD4) where we met with at least 5 different vendors of scale out storage. All the blogger participants were starting to call this the “Scale-Out” field day. It turns out that the compute requirements for storage are starting to increase, for many reasons not the least of which is the performance of SSDs. This rising compute requirement generates a need for scale-out storage.
Second is software defined storage. Howard took a stab at defining it and in our view software defined storage is delivered as a software only solution that provides storage and compute services together in one server environment. With a 2U server, one can have a couple of SSDs and a gaggle of HDDs and still only use 4 of the 24 cores to supply storage services, leaving the other 20 for compute. What with VMware’s VSAN and the other software defined storage players, this is becoming another hot trend this year.
Finally, whither the disk drive? Drive capacity continues to grow with no end in sight, with helium, HAMR, and shingled magnetic recording. SSD is not killing them off as quickly as we thought, even though SSD costs on $/GB basis keep coming down. The net effect of this is that both of us believe disks are going to be around for the near term (5 yrs or so) but we differed on the long term prospects of disk.
