DL380 G7 with P410i Getting Horrible Read/Write Speeds (Server 2012)
All my HP servers have a P410i Array Controller. If I put Server 2012 on any of these machines I get horrible read speeds.
I can copy a 4GB file to them at normal speeds (120MB/s). But if I try to copy 1,000 files that total 500MB I only get about 1.2MB/s).
Here's an ATTO result which shows something is very wrong:
The driver is the most up to date 62.24.2.64 (26 Oct 2012) as is the FW 5.70 (D) (20 Nov 2012).
I would appreciate any help!

Re: DL380 G7 with P410i Getting Horrible Read/Write Speeds (Server 2012)
hi,
I don't see any errors in the report.
You can update the FW of the hdds.
Are you facing the same performance issue in other servers, but with different hard drives or you have the same type of drives in all your servers?
Thanks
regards

Re: DL380 G7 with P410i Getting Horrible Read/Write Speeds (Server 2012)
Some are HP, some are not.
Some are SAS, some are not.
Some are 3.5", some are 2.5".
Some are single drives, Some are RADI5, Some are RAID10.
All my P410i machines are affected. Any time I try to install Server 2012 or upgrade R2 to 2012 they become affected with this horrible transfer rate on small files.
I haved two machines that use a P400i and they are running server 2012 fine.

Re: DL380 G7 with P410i Getting Horrible Read/Write Speeds (Server 2012)
Well, at least I know it's not just me. A friend who has DL380 g6 and g7 is having the same exact issue.
However, if he uses the default drivers from server 2012 he has less of an issue. So then my problem is, I'm using HP drivers and having this major issue.
Is there any way to find/get/extract the windows drivers and replace my HP drivers?

I'm presuming you're using the drivers from the October 2012 HP Service Pack for Proliant?

Re: DL380 G7 with P410i Getting Horrible Read/Write Speeds (Server 2012)
That is correct (2012.10). I also used the package before that with the same problem. Once I saw that the October build claimed it added "Server 2012" support I was excited to get the problem fixed. Then I was greatly disappointed when the problem persisted.
I spent yesterday finding a way to extract the Server 2012 WIM file (had to use an alpha 7-zip build). I took the drivers from the installer wim and loaded those. Same exact results. Once the test hits 512 the read speed goes to pot.

Re: DL380 G7 with P410i Getting Horrible Read/Write Speeds (Server 2012)
The other thing I would be curious about is your mix of drives in the individual arrays. Are you mixing SAS/non-SAS, HP/non-HP in any given array? Also, I would look at 3G/6G, spindle speeds (10K/15K), single port/dual port... in the old SCSI world (if I'm not mistaken on this!) a mix of drives would drop down to the lowest common denominator for transfer rate and bus width across all drives in an array - which could murder the speed.
The other thing that could be at play is a flake in Win 2012 - or one that still exists from every previous version of windows Server I've worked with. I haven't messed with 2012 at all, but I know from previous versions of Windows that the WORST thing you could do to the Windows filesystem is throw a scratload of small files at it. Folders like that would destroy backup performance - and still do, frankly.
