I've tested about 12 different Dell servers. Ony a couple of them have Idrac express and all the others have Idrac Enterprise. All the boxes with Enterprise perform poorly and the couple that have express perform well. I use the disks in raid mode on all of them. I've tried a few non-Dell boxes and they all perform well even though some of them are very old. I've also tried

Thanks for the suggestion. I tried both of these with no difference in performance.I have tried several other Dell hosts with Idrac Enterprise and getting the same results. I also tried a new Dell T130 with Idrac express and was getting over 700 MB/s. Any other users had this issues with Idrac Enterprise??

I would be really supprised if the problem was related to Idrac. The Idrac processor is a stand alone cpu with its own nic and runs independent of the main CPU. That being said it does have visibility into the whole system. try using dmidecode to compare the systems and take a close look at the raid controllers and what size and form of cache they have.

Here is info. about the Raid controllers. Doesn't seem to be the culprit. Slow host: Name PERC H710 Mini (Embedded) Firmware Version 21.3.4-0001 Cache Memory Size 512 MB Fast Host: Name PERC H310 Mini (Embedded) Firmware Version 20.12.1-0002 Cache Memory Size 0 MB Slow host: Name PERC H310 Mini (Embedded) Firmware Version 20.13.1-0002 Cache Memory Size 0 MB Slow host: Name PERC H310 Mini

I don't think it is related with iDRAC itself but some configuration is wrong or there is some hw error. Did you check battery of raid controller? Do you use disks in jbod mode or raid mode?

What is your gluster setup? Please share volume details where vms ate stored. It could be that the slow host is having arbiter volume.

All volumes are configured as replica 3. I have no arbiter volumes. Storage hosts are for storage only and Virt hosts are dedicated Virt hosts. I've checked throughput from the Virt hosts to all 3 gluster hosts and am getting ~9Gb/s. On Tue, Feb 27, 2018 at 1:33 AM, Alex K <rightkicktech at gmail.com> wrote: > What is your gluster setup?

I have a 3 host gluster replicated cluster that is providing storage for our RHEV environment. We've been having issues with inconsistent performance from the VMs depending on which Hypervisor they are running on. I've confirmed throughput to be ~9Gb/s to each of the storage hosts from the hypervisors. I'm getting ~300MB/s disk read spead when our test vm is on the slow Hypervisors

"Did you check the BIOS/Power settings? They should be set for high performance. Also you can try to boot "intel_idle.max_cstate=0" kernel command line option to be sure CPUs not entering power saving states.

Just a note to pass on in case anyone runs into the same situation. I have a DELL R510 that is running just fine, up until the day that I needed to import a pool from a USB hard drive. I plug in the disk, check it with rmformat and try to import the zpool. And it sits there for practically forever, not responding. The machine still responds to network connections etc., it''s just the

I am currently using a Dell PowerEdge server R610 with Xen 4.0 installed and the 2.6.31.13 pvops kernel. I am accessing the server console using the iDRAC KVM feature of the dell management console. Does anyone know how to configure the console option in the grub menu so that all the boot messages can be seen on the mgmt console? Currently I can view only the Xen bootup messages if I dont specify

Hello, I just tried out XCP and I was surprised to see it looks pretty much like Xen from Citrix. Based on the RPM packages installed, I assume XCP is based on RHEL5. With that in mind, I have a few questions that I did not find an answer on the web... Perhaps I didn''t look in the right places, so if you know about any good documentations that I should read please share it :)

Hello I have more and more troubles using firefox in professional environment with CentOS6. The latest version is 45.7.0 But I can't use it anymore to access some old server hardware (IDRAC7 of DELL C6100) because of "/SSL_ERROR_WEAK_SERVER_CERT_KEY/". I had to install an old Firefox32 version to administrate these servers. Today I upgrade the firmware of 2 DELL switch and now
