ViPR SRM - which server virtualization technologies are supported?
Which server virtualization technologies can ViPR SRM report on and what does it provide for visibility?

ViPR SRM supports the following server virtualization technologies:
VMware vCenter and IBM LPAR data is normalized and is visible under the single pane of glass view represented by the Explore node. Under the Explore node, you will find a CI Dialog for each device ViPR SRM is configured to collect data on - Virtualized Host for the purposes of this discussion. (CI stands for Configuration Item and is another name for a ViPR SRM device.) Within the Explore node, for a virtualized server, here is the list of major use cases covered within the CI Dialog:
In addition to the above use cases, Chargeback by Host use case is also fulfilled under the Explore node.
To go into the specifics, here is a CI Dialog for a VMware Virtual Machine, invoked from within the Explore node. It covers, in a single shot, the End-to-End topology view for the VM, its basic attributes and all the reports available for the VM.
Between the topology map and Storage Path Details, you have information around both physical and logical connectivity at your finger tips:
Before we move onto other use cases, here is the CI Dialog for a VIO client. As you can see it looks very similar to the one for VMware’s Virtual Machine.
Reviewing the Capacity reports next for VMware VM. List of Datastores, with usage breakdown, capacity of each Virtual Disk and the Related LUN can be found here.
Similarly for a VIO client, details around Volume Groups and Disks are reported on.
Chargeback reports can be found under Explore >> Storage >> More Reports >> Chargeback by Host node.
This is really just the surface, there is so much more to explore in this node.
I do want to switch gears and talk about Report Library a bit. So, if Explore node is all about generalizing/normalizing, Report Library is all about specifics. Explore node gives us a uniform view across a VMware VM and IBM LPAR/VIO on the other hand Report Library will bring out the differences by pointing out the specifics. Here is a quick glimpse of VMware vCenter vs. IBM LPAR Report Library.
Currently Microsoft Hyper-V is only supported within the Report Library. Which means it hasn’t gone through the process of data normalization yet and so is not supported in all the of the reports available under the global Explore and Dashboard report. But we still have the specifics available.
A nice summary for hosts is available:
Another example would be availability of Volume Allocation information:
This is really a glimpse of what’s available around virtualized servers. If there are specific questions that we can get answered, please let us know.

Is there a way to bulk export to a spreadsheet the information depicted by the Topology "Masked Storage Systems with Replicas". I am attempting to produce a system-wide spreadsheet that has server to storage system relationships regardless of capacities, etc.
Possibly there is a better solution.

What perspective would you want that from? It's potentially a many-to-many set of relationships -- one host can have storage from many arrays, and one array will have storage for many hosts. It will make for a very unwieldy (and probably extremely large) spreadsheet -- potentially tens or hundreds of thousands to millions of rows, if you think about every combination of host(s) and volumes.

It would be from the server perspective. It would be a one-to-many relationship but in our case a manageable one. Ideally, the basic information needed would be: server, primary storage array, replicated storage array. There could be multiple arrays associated with each server.

Sounds pretty similar to the view in All>>Explore>>Storage>>More Reports>>More Storage Inventories>>Replication, with the exception that that view is at the LUN level rather than the host level. You could use the columns widget (grid icon near the thumbtack, top right of table) to re-order the columns and hide any you don't want.

Dan,
Previous response had expanded local links in it....
...............................
Thanks for the response. Actually, my need is for all server to storage array relationships, including replication targets. I duplicated the Replication report, removed the LUN specific columns and removed the “name is ReplicaPath” filter. The resulting report contains far fewer servers than the All > Explore > Hosts report. I think possibly the difference is that when looking at the “Hosts” report in edit mode, there is a sub-entry for passively discovered hosts.
I have cloned: All>>Explore>>Hosts>>servername>>Device Summary>>servername>>Path Details & Storage Connectivity>>Path Details & Storage Connectivity>>Path Details which is close to what I need but it appears to be at the “Host device” level. ..... I made changes to the cloned version and now have information based at the server/array level but am missing some servers which are in the Explore >> Hosts report. I don’t know why....
In the old ECC, it seems as if there were the capability of extracting a list of all “Masked” storage by server. This is possibly what I need, if it is available in SRM. Are you aware of such a report?
