My N40L server

Recommended Posts

schoondoggy

Sometime ago in another thread we were chatting about builds and performance.

My N40L has the stock BIOS and;

8GB of memory.

HP410 RAID controller with 512MB cache.

Two mirrored WD VR 250GB 10K SATA II drives for WHS2011.

Four 2TB 5400rpm SATA II drives in a RAID 5 for data.

USB 3.0 available via WD card

IcyDock for the two mirrored drives and a BD drive.

Here is the system;

Very stable and functioning fine.

Curious on thoughts why the numbers look better for the SEQ read/write in the RAID 5 vs the 2 VR mirror?

The numbers for the mirrored pair are about the same as a single drive which is what I would expect.

RAID 5 performance gets better as the number of drives increase, to a point.

The RAID controller is reading and writing data from multiple drives, so sequential is easier to perform well.

I will run ATTO and HD tune and see how they look.

More benchmark data, each tool seems to represent performance differently;

RAID 5:

In the end, I think file transfer measurements are perhaps more meaningful. I have to wonder if the cache on the RAID controller confuses ATTO.

Nice looking Machine Schoondoggy!

 

Did you have any issues with the WD card installed with the P410?

 

With a RR2720 the WD card is not working in my N54L and when I switch out the WD USB3 Card for the Intel NIC the N54L doesn't see the RR2720 at Post.

It's a shame JM, isn't it. PCIe was supposed to resolve all these conflict issues. The cards are supposed to negotiate with the bus controller and wind up using settings that don't conflict :P

I had no issues with the WD USB 3.0 card and the HP P410. The only problem I have with MicroServers is accessing the pre-boot configuration settings on LSI and Adaptec RAID cards. Seems to be a memory space issue.

The one concern with the HP P410 is that it only support SATA speeds up to 3GB, but it will do SAS up to 6GB. 

After some 'creative' trading my N40L now has;

two Seagate Savvio 300GB 10K SAS drives mirrored for the OS and four Seagate Constellation 2TB 7200 SAS drives in a RAID 5.

Performance of the mirrored SAS 10k's;

I will be moving this storage over to the N54L when it is ready.

The pictures don't show up...and links to appear to work.

 

Edit: Appears this issue was my corporate network firewall

That's odd they show up for me, even when I sign out?

Can anyone else see the graphics in my last post in this thread?

Thanks.
