How's everybody doing?! Hopefully awesome!
During this last week I deployed a ScaleIO (v1.32) inside ESX (we had 7 servers total with a bunch os disks). I read a lot of docs and watched some videos on Edutube. But I have some questions (probably noob question, sorry about that) but better ask'em right?
Here we go.
That's it. A lot of question... Sorry...
Thanks a lot!
1. The ScaleIO gateway provides a REST API, as well as a web-based installation/upgrade manager.
2. The management network is separate from the data networks, as you will generally need to manage hosts from IP addresses outside the data networks. It also doesn't need to be 10gbit, like we recommend the ScaleIO data networks to be.
3. Not quite. Unless you've configured them to be dedicated to one kind of traffic, interfaces/IPs on an SDS serve both SDS-SDC traffic (volume access) and SDS-SDS traffic (rebuilds, rebalances, and second copy writes) equally.
4. I'd best let a Solutions Architect answer on this conclusively, but don't forget that you will also need an IP on each subnet for every SDC as well.
5. Xtremecache software is an option, as well as LSI RAID controller CacheCade. Without either option, you are correct that you'll be best to set a separate pool for SSD.
6. Correct, the SVMs (ScaleIO VMs) live and die with the host they belong to.
Thank you Mr. Rush!
Probably there are a lot of ways to control how ScaleIO uses every network it has but after you install it. The wizard on vCenter is kind of limited...
Hopefully an architect can shed some light on that big deploy question (number 4) but I think it's possible (or at least should be) but probably is some post install configuration done trhough the CLI...
I dug a bit more and found the answer for question 4. Apparently you can have up to 8 IPs in each SDS (serving various purpouses), and in each IP you can decide its function. And that's done though CLI commands.
