I think of SONAS in the same way. There are many ways to do NAS technologies. Some take time to develop and build, but others are just as effective with little to no planning. I was talking to a client the other day and his response to NAS was to put NFS servers in all of their locations. It's cheap and something they can repeat like a cookie cutter many times over. What he was not taking in to his planning was administrating all of these islands of storage and how much he was spending on data sitting on expensive disk. If he was able to consolidate these servers and have a way of moving data around and eventually off to the greenest storage media out there, tape, then how much more money and time would that save him? He didn't have an answer but we are working on plan for him today.
IBM announced yesterday that SONAS version 1.1.1 will now support ILM tiering with GPFS and then moving data off to tape using Tivoli's Storage Manger HSM. These two work in concert with the policy manager on the SONAS system to move data on and out of pools based on the meta data properties. As discussed in previous posts, SONAS separates the meta data which allows the scan engine to pass the needed data on to the ILM or TSM agents. These agents then move data between the pools and allows the client to free up space on valuable spinning disks.
If you are one of the people that says tape and tiering is not needed, then think about the idea of putting data that hasn't been touched on a disk that costs $0.03 per GB. Its not that your storage isn't cool and you may not need tiers for your high performance, but what if the only data that was on the system was data that was actively being used and not my old spreadsheet from 2009.
Along with the ILM announcement, IBM released the following with version 1.1.1
- Asynchronous Replication
- SONAS with IBM XIV storage
- Higher capacity SAS drives
- HTTPS protocol support
- Network Information Service (NIS) support
