If you are deploying EMC PowerMax into your environment, and are an OCI customer, you:
#1. Are very likely going to need a datasource patch
#2. You really want to take this opportunity to reassess what EMC Solutions Enabler versions are deployed in your environment.
If you have OCI Solutions Enabler datasources, you want to map out:
Which datasources live on which Acquisition Unit?
Are those datasources utilizing Solutions Enabler "client / server" mode, or do they have "local" access to Symmetrix arrays?
When you have more than one Solutions Enabler datasource on an AU, that implies that at least one of them is using client / server mode. It is at this point, you need to start contemplating what the SolEnabler version is on those servers.
Datasources X,Y and Z live on one OCI AU. That OCI AU can only have one Solutions Enabler version installed. That SE version needs to be the same as, or older, than the servers that those 3 datasources talk to.
If you have 8.3, 8.4 and 9.0 installed on those 3 servers, you can only conceivably install SE 8.3 on the OCI AU because that is the newest version that is not newer than any of those 3 servers.
But the problem is - if you are using 8.3 as a client against 9.0, is that going to return reliable information about a PowerMax, given that 8.3.x pre-dates the PowerMax by a few years? There are likely going to be aspects of PowerMax that 8.3 cannot express.
So, in situations like this, you may need to:
Deploy new RAUs, on which different SE versions live, to live in harmony with version matching rules
Maintain SE version standards / avoid SE version sprawl - don't only deploy SE 9.0 where you need to for PowerMax - instead, deploy it consistently to avoid version compatibility headaches.
I don't think there is really anything specific about PowerMax in SP8 - I believe most of the fixes/enhancements required for PowerMax landed in SP7 or earlier, but I do generally recommend running the latest SP to stay current.
Any time you are doing anything new with Symmetrix, it is always a good time to assess your layout:
What Solutions Enabler datasources exist?
On which AUs do they exist?
What Solutions Enabler version is installed on those AUs?
If datasources are using SE in client/server mode, what is the server side running?
You may find something like: AU X has datasources 1 and 2 installed, which are talking to remote SE versions 8.4.x and 9.0.x. If that AU X has SE 8.3 installed, you might have problems. You should look at upgrading that SE 8.3 install to 8.4.x to match the oldest server side version in use. It would probably be ideal to actually see if you could get the 8.4.x server to the same 9.0.x version, and get the AU to 9.0.x as well to match - the fewer SE versions you have deployed, the lower the chances of interoperability issues
Meanwhile, I'm also talking with Dell EMC folks and they said, that they do have REST-Interfaces also and that we should look more in this direction, as it looks like SMI-S will be faced out over time. Whatever this means with Dell EMC being Dell EMC.
Are there any plans for the near future to bring a REST-based DataSource for OCI?
I have also a question, does the data source set the SYMAPI_CONNECT variable under windows? I actually would like to have only one RAU that collects all data from all Powermax-systems instead of multiple once. Or do you have any suggestion on how I could get the data from only one RAU?
