more serious HDD tester: post IOmeter results

[Speederlander]

How mutch ram do YOU have

"All my application and game installs!

You can't have many new games on the ramdisk, because new games are too big!

2 games, and the ramdisk i full. Doooh

When I am done with a game I remove it. I don't play that many games and when I do, I finish it and remove it.

I only put applications that benefit from the speed-up on the ramdisk. I have visual studio, masm, etc. I don't waste space putting office and other unnecessary apps on it.

Anyway, I'm going to 32GB system memory (with 26GB ramdisk) for a reason.

[Speederlander]

Very Impressive!

What system do you have exactly?

Supermicro X7DWA-N, dual harpertowns, 16GB Kingston 800MHz FB-DIMM going to 32GB next week.

Superspeed RAMDisk for all my application and game installs:

My two X25-Es have 5.0k, 8.4k, 11.0k, 9.2k for ques of 1,2,4,8 respectively. Pretty close. If the friggin adaptec controller wasn't gimped they would do more

At some point there are limits because it's fb-dimms. But you can't possibly have safe large ramdisks (i.e. >=12GB) w/o the full ecc protection. But hey, 57K iops does it for me.

mm I quoted the wrong post last time. Ramdisks FTW indeed, but I can't lose the CPU OC personally

Yeah, no real OC. But I BSEL'd my two harpertowns from 2.5GHz to 3GHz. Not too bad for an 8 core machine with 16GB RAM.

Great! I thinking about X58 + 12GB DDR3 system..4GB for OS and 8GB for Ramdisk.

[Levish]

x58 will take 24GB of ram in the 6 socket system, you are limited to the slower stuff for double sided sticks though (which 4gb will almost certainly be). check through the manuals

Testing on a Single 750GB Spinpoint....

How long does it take to prepare the drives. My drive is really fragmented. Is it sorting that out?

It's been preparing for almost half an hour

But that much RAM not ECC is not advised.

Depends on the speed of the drive, if i remember correctly the posted test creates a 8GB file for use in 4k random write testing. 15-30 minutes isn't unreasonable.

Yea, SSDs and Ramdisk dominate here

Better defragment before test and ideally test it on a dedicated partition in the first say 50GB. That is where usually your OS and other application go and that part of the conventional disk is faster

[Mads321]

I want to run this app. and use the numbers for at review of some SSD's in a short whle, but I have absolutely no idea what all theese numbers are, and what they mean.

Anyone care to enlighten me on the subject, or at least point me in the right direction to understand theese numbers good enough to explain them to an audience?


Thank you very much in advance!

4x 74GB 15kRPM Fujitsu SAS drives on Adaptec 5405 in RAID10

[Jurgen_vdp]

These are my test results from withing a VMWare environment over an 1GB iscsi link and on the local drive. IOMeter was installed on a virtual machine running Windows Server 2003.



Think that are pretty neat results. VMServer is an HP DL380 G5, openfiler server is an HP DL380 G4 (3GB RAM, 6 x 15k U320 72GB).

[Levish]

definitely neat results, the Openfiler thing is to the same disks as the 2nd result? Roughly how old are those SCSI disks?

No, I have a DL380G5 with local disks about 2 years old (6 x 72GB 15K 2,5" SAS on an Smart Array P400), the second test is on these drives. I installed ESX 3.5 on this server and use it for demo purposes. The virtual machine is on this server. I created a drive on the local storage and a second drive on the iscsi san (with openfiler).

For the first test I installed openfiler on a HP DL380G4!! (with 6 x 72GB U320 15k disks 3,5"). This is a 4 year old server. It is connected over a 1GB Broadcom NIC and a HP 2910 switch. The results are from a disk on the openfiler system via iscsi.

[Levish]

very cool Jurgen

[Jurgen_vdp]

Yeah, it works great actually. Getting some nice speeds on older hardware. Just takes some time to configure, but the VM's work at a very acceptable speed I also have a production SAN, but cannot benchmark it, as it is used 24/7 (Supermicro SAN, 24x300GB 15k SATA on an Areca with 4GB cache, connected with 4x10Gb to a vmware cluster). Early tests gave a transfer speed of almost 1GB/sec.

[philip j fry]

The discs are 15K RPM's from HP.

some decimal , . errors but still readable.

[ping2low]

...I still have 3 open channels waiting for X25s...can't wait!

[Shogan]

This is a massive thread revival, but just got my first SSD the other day (about time) and decided to see how it compared. Both results from the same system on SATA.
