Is anyone on ScaleIO 2.0 yet?

Is this something I should look into for my home lab?
Will it give better performance if i dont have ssds etc in the storage setup?

Edit: found some more information, and I dont have enough esxi servers at home to use this :)

I don't believe all N nodes (minimum 3) need to be esxi. Do you have a 3rd host you could throw centos or whatever on?

there is no association with your compute and storage nodes. you can have 5 hosts for storage use 2 of those for ESXi/HyperV and other compute nodes. ScaleIO does not care.

I just deployed it in the lab at work. (Gave him some RDM from the NetApp, VNX and Dell storages just to test) For now, it looks really good. (We don't have nodes that have internal storage. We're full of blades after all...)

Followed the upgrade guide to go from 1.32.2 to 2.0 and everything worked as expected with zero downtime. I run this on a 3 node vmware vsphere 6 update 2 cluster in my home lab. The hardest part was locating the correct older software packages from 1.32.2 to load into the gateway server during the upgrade process. The steps went something like:

1. Unregister old scaleio vcenter plugin
2. Register New plugin
3. Change option within new scaleio plugin for unsecure mode and reregister.
4. Upgrade required packages on sds nodes (java and openssl)
5. Load new scaleio 2.0 packages to the gateway
6. Load old 1.32.2 packages to gateway
7. Deploy sds upgrade from the gateway and reboot nodes one at a time.
8. Upgrade other required packages
9. Upgrade SDC vsphere packages
10. Enable secure communications
11. Manually deploy extremeio cache packages
12. Upgrade GUI tool

The single best benefit I can find for a tinker'er like me is the planned maintenance mode. Rebooting an SDS node while it is in maintenance mode will not cause an immediate rebuild. The new integrated ssd caching really seemed to improve my array's responsiveness as well.

Here is some info:
Node1: 1 Xeon x5650, X8DTN+, Dell H310 IT mode flash, 32GB, 8x 7.2k sata, 1 250GB 850evo, connectx-2 10g
Node2: 1 Xeon L5630, X8DTN+, Dell H310 IT mode flash, 32GB, 8x 7.2k sata, 1 250GB 850evo, connectx-2 10g
Node3: 1 Xeon L5630, X8DTN+, Dell H200 IT mode flash, 32GB, 8x 7.2k sata, 1 200GB SAS OCZ, connectx-2 10g

Sata drives are random sizes between 1T and 5T. Using 3x Supermicro CSE-826 chassis with 6gb sas2 backplane.

Recently added the Dell 6224 switch with 2x dual xfr 10gb modules. Averages 600 watts at the wall.




Benchmarks. Read latency as reported by vmware was under 20ms during testing. Write latency spiked to 40ms+.

Almost 5000 iops!

My 8 node cluster (DR site) went up to 2.0 three weeks ago. The original configuration had some issues with LIA so I ended up having to rebuild that portion. Otherwise, the install went smoothly with no downtime. Anyone else digging the new ease of use changes in the GUI (volume resize, etc) ? I saw maintenance mode mentioned earlier - agreed 100%.
