Slow Performance with a S130

Jump to solution

Hi, Just taken delivery of a PowerEdge R630 which has a Perc S130 RAID card with 4*250Gb 7200 RPM SATA disks in a RAID5 array and we're experiencing unexpected slow performance.

Using CrystalMark, the max Read speed we're seeing is 12MB/s, with write as 7MB/s. I know it's software raid, but I was expecting a bit more performance than that.

The latest drivers were taken from the dell web site (4.0.0.37) and looking back, the windows server install took a lot longer than usual.

I know it's soft raid, rather than hardware accelerated raid, but I would have expected the performance to be significantly better than it is (I have a NAS here with software raid providing 90MB/s read/write with just an Atom CPU, Not 2*Xeon E5-2620 v3.

Many thanks.

"No, the S-series controllers are garbage. My recommendation is that if you care enough about its performance to ever even consider running a benchmark, then don't use it."

Agree this controller is useless, Dell should cease using these low end devices ( notice I did not call it a raid).

Now all you users can spend an inordinate amount of time trying to figure out the issue , wait for a possible solution ( long and unlikely, as it was broken to start) or you can buy a real hardware raid. Personally I inherited a couple clients with low end devices, and did not waste any time,  I just purchased real hardware raid controllers.  Being arrogant/angry at Dell is not getting your raid subsystems up to par , Hey if you order a Porsche with a VW Beatle engine don't expect it to win races.

We've upgraded the server with a PERC H330 Integrated RAID Controller. Read speeds are now normal (above 100Mb/s) and we can finally take the server into production. Lessons learned. Never buy a software RAID from Dell 🙂

No, the S-series controllers are garbage. My recommendation is that if you care enough about its performance to ever even consider running a benchmark, then don't use it. Use OS-managed or hardware RAID - even the low-end hardware RAID will be preferable. From what I hear, RAID 1 isn't horrible, but RAID 5 is the biggest loser when it comes to performance.

RE: Slow Performance with a S130

Hi there,

We experience the same problem with the same hardware. A brand new PowerEdge R630 with a PERC S130 RAID. We use a RAID-1 configuration. Write speeds are good, but read speeds are terrible. Around 10MB/s.

We have other Dell servers with software RAID (PERC S100) and never had these problems before. It looks like there is something wrong with the S130. It is slow out of the box. We have installed the most recent firmware and drivers, but no difference. Hopefully Dell will address this problem.

Did you contact Dell support about this problem? Do you have any updates?

Not contacted Dell, was hopeful that they actually monitored the forums, hate logging support through phone calls, especially when its technical, and I've done some prep work.

Its a shame that the performance on RAID1 is not much better, was thinking about migrating over to RAID-10 to see if that improved matters, but as it's still slow on RAID-1, there might not be the point.

Other option is to add a hardware RAID card as an after purchase addin.

We have the same problem with the support by phone. They let you do all the things we've already checked and verified (run diagnostics, update drivers, etc.). In this case there is definitely something wrong and Dell should investigate and fix it (I have the hope this is a fixable software bug).

In our case the OS (windows 2012 R2) was pre-installed and the read performance was bad right out of the box (before we did install anything on it). The fact that you are experiencing the same problem with the same hardware setup would suggest that this is a reproducible problem with the PowerEdge R630 in combination with the S130.

We've spent nearly EUR 6000,- on a new server which read performance is worst than the read performance of the old server we are planning to replace (a 10 years old PowerEdge 2850). I don't like that...

Hopefully a Dell employee notifies this thread and is able to help us and elevate the problem to a technical team. I will submit a new thread with a link to this one, to gain attention... Let's keep each other informed on any updates.

PowerEdge R630 + PERC S130 disk performance issues

Jump to solution

We have a brand new PowerEdge R630 with a PERC S130 RAID in a RAID-1 configuration. The system has terrible read speeds. Around 10MB/s max. The OS (Windows Server 2012 R2) was factory installed, but the system was slow out of the box. We've updated all firmware and drivers to the most recent version (4.0.0-0037), but the problem persists.

There are other customers with the same hardware setup who experience the same problem. See this thread:
commweb-ps3.us.dell.com/.../20817104


I'm trying to collect more customers with the same problem. We think this a software bug or hardware fault which should be investigated by Dell. In our case we bought a EUR 6000,- machine with a read performance worst than the read performance of the old server we are planning to replace (a 10 years old PowerEdge 2850).

We never had these problems with other Dell servers. I know the S130 is a software RAID, but we have plenty servers with earlier versions of this RAID solution (like the PERC S100) and they perform fine.

I assume this migration was done without data loss?  Can you explain the steps taken to migrate from S130 to H330?

Unfortunately not. We've had to rebuild the RAID and do a complete OS reinstall. It took quite some time to get everything up and running. Also the new RAID card was delivered without the necessary cables (Dell thought the right cable was already in the server which was not the case :-(). So we've planned a datacenter visit only to find out the right cable was missing. Contact Dell again, wait for the right cable. Back to the datacenter again and fit the hardware and reinstall OS and applications. Now everything is running very well. Bottom line: Dell should stop selling software RAIDS!
