I have two 7400's, 24 SSD, 148 FC, 60 NL.
I have two Proxies, HP DL380G9's (Dual 12 Core, 32G ram) with Brocade/QLogic 1862's with 16GFC/10G Ethernet.
I use Thin VV's with Thick Eager Zeroed.
My 3PAR's are seperated by roughly 66k of DWDM. Two 10g for Ethernet, two 10G FC (Roughly 500ns return). <--This is my only complicating factor
I back up to FC Storage, with a copy job that then moved the job to a StoreOnce appliance for longer retention.
All of my hosts reside on 1862 Brocade's as well, same 16g/10g setup. I use storage snapshots for my backups. My hosts are also running 5.5.
When speaking to support a year or so ago, I was told the speeds I'm getting are normal, that I wouldn't see any faster. I don't have any fabric errors or port errors, everything seems to be running very clean. An active full will net me 188 average. I also get 99% Source, 24% Proxy, 1% Network, 1% Target (That math seems a bit off too rofl).
I'm running Flash Caching, I was taking a large amount of hits. I tend to stay around 25-30% during my peek traffic times.
You have an awesome system, and you are getting the same low numbers as me, compared to the systems both of us own.
I changed fillword, and all errors are gone.
I changed my test server to thick eager zeroed.
Ran new back, same speed.
I really dont get it, it seems like there's a cap somewhere.
If i put 4 servers in a new job and run a full, i push 400 MB / Sec, but still.. why the f*** cant i push more than 190 MB out of a single vmdk.
Was thinking of creating a test lun on SSD just to see if that actually changes anything.
I have no QOS setup in my 3par.
Have you tried to run diskspd.exe from your proxy on a ntfs formatted lun you present just for testing? I know it is not the same thing, but just to test to see how much 3par can deliver? Alternatively run it in a vm, then you are throug the vmkernel api...
How much will you get with 4 servers in one job?
Support tell's me that they have never seen anything run 1000 MB / Sec or anywhere near that.. but WHY???
