I am in need to find the port utilization of my Hitachi USPV and VSP storages in my envioronment.
Please let me know, how to check the port utiliztion of the storages.
Thanks in advance.
If you have Tuning Manager, you will get all the information's handy.
If you don't have tuning manager you can do exports and sort through the data using a spreadsheet application.
how to do exports..??
I will tell my requiremnt. If I have to add a new host, to the storage, how I will select the particular port.
I'd like more detail about this- I have tuning manager and quite frequently, it simply doesn't have a way of presenting the information I need.
What kind of export are you talking about?
The USP-V has an export tool. Information can be found in the MK-96RD617 manual.
"Hitachi Performance Manager User's Guide"
The VSP also has an export tool. Information can be found in the MK-90RD7020 manual.
"Hitachi Virtual Storage Platform Performance Guide"
Too much info to post. Suggest you read up about it. No a lot of hitachi customer's use it -- although it's available to them.
We take exports when we have a ticket. Are you saying that the data from that export tool contains performance information? Can you give me any hints about where I could look for it? We've always just tarred it up and shipped it to HDS.
Different kind of export.
I just checked and the export tool described on pages 131-204 of MK-90RD7020 (http://www.hds.com/assets/pdf/vsp-performance-guide.pdf) are indeed the exact same export tool we use when we're supplying data for an HDS ticket. There's a nice description of each of the files in there, though.
Good deal.. I thought it was a zip file that the export tool created and inside are a bunch of CSV files.
I don't want to pretend I use the export tool as I'm only aware of it and no so much familiar with it.
Any update for my query..?
It's not easily explained in a post. I referenced the documention in an earlier comment. I suggest you review the documentation. You also need to obtain a copy of the export tool related to your microcode version.
In short, not easily without tuning manager. As someone who uses tuning manager, not even that easily with it. In my environment, to solve the problem you're having, I've approached it from the host OS instead of the storage. It's simpler and scriptable. Simple have all the clients observe their MB/s and keep averages per port, and refer to that data when choosing where to put a new hostgroup.
If you're just looking for a high-level view of your ports and which are the most utilized, the Hitachi Command Suite with Tuning Manager now has a Health Check Report. This report shows 1 week's worth of data, albeit at only 1 hour granularity. There are Top 10 Ports by IOPS and Top 10 Ports by MB/sec, among other metrics. Screenshot attached.
However, if you want more than 10 ports or more granular data points, both Tuning Manager and the Export Tool (detailed on page A-1 of the aforementioned VSP Performance Guide) are the way to go.
But how to get this report. I couldnt find any such health check option in my tuning manager.
The report is actually schedulable within HCS (Device Manager) on the Anayltics tab, but it uses Tuning Manager data.
In HICMD SUITE once a logical group is created ( host/ldev etc) you can then drell down on the performance of the host\luns etc based on your HICMD setup\version ( 7+) is required and wheatehr or not you have proper licence ( Mobility).
You can launch and view performance from Analytics Tab that i find to be quick and easy, you do have to do a prework with creating logical groups & i have had problems discovering configured host in the search tab, generally sercing by ldev works better.
This reports can be very quick and can go back a while, so just setup a logical group and get familier with it, there is even a tutorial on this site on how to use this features, look at the link on home page.
I do hope someday HDS will enhance this feature to export the graphs and data to share.
Hope that helps
If you have a logical group with the LUNs in question, is there a way to get the throughput numbers? What I found with the wizard (from the performance problems button) is latency and IOPS.
Hi Lachudippu K, has Michael Taormina's last answer (Re: Port Utilisation of Hitachi VSP) helped you figure this out?
