Hi, Any folks on this list who have installed CentOS 6.3 on the new Dell Poweredge R815 servers? How was your experience? Thanks -Surya -- Surya Saha Department of Plant Pathology and Plant-Microbe Biology Cornell University, NY, USA http://www.linkedin.com/in/suryasaha

hi guys I wonder if any of you might be using SFN6122F-R7 SFP+ (SFC9000, same firmware everywhere, Centos 7.5 too. I'm trying poor man's setup to get the servers onto 10GbE network. Setup is such that three Dell R815 are connected to each other, each has one Solarflare(SFP ports) and each Solarflare is set as net-team(both ports on a card are net-team device) with runner in broadcast mode. And it all seems to work, they ping each other, iperf okey. The problem, big problem is that when traffic start to flow...

Hi, I have a strange phenomenon that I cannot readily explain so I wonder if anyone here can shed a light on this. The host system is a Dell r815 with 64 cores and 256G ram and has centos 6 installed. The five guests are also running centos 6 and are running as a hadoop cluster. The problem is that I see disk-io spikes in the vm's which then cause soft lockups in the guest but I also see hanging processes on the host as if the entire...

Hello, I run CentOS 5.6 on a Dell PowerEdge R815 with 256 GB of RAM. We use Sun Grid Engine to schedule jobs on this node. I want to limit the memory usage about 150 GB per process. So i use the /etc/security/limits.conf configuration file. I test this configuration with some tools with a lower GB limit (about 2 or 4 GB), and it works ! But,...

hi guys I have a lxc guest on Dell's R815(AMD Opterons) which I just moved to an ecryptfs mounted folder(using centosplus' kernel C7.5) Copying data to that folder seems to work just fine, but I as soon as I start the quest, the host gets shot in the head almost immediately, hard reboot, no dump. I also have another, virtually ide...

Hey, folks, I'm working on finding some new compute nodes. What I'm looking for is a 64 core box, with room enough for a lot of RAM. I can get it from Dell, or HP (bleah! a 4U box), but I need to have three quotes, y'know. We've gotten a lot from Penguin in the past, but they're all Supermicro, and we've had a *lot* of problems with the 64 core boxes, so I'm looking

Hello, I've two twin servers (Dell PowerEdge R815) dedicated to kvm+libvirt and they have the same exact CPU (AMD Opteron(TM) Processor 6272) with the same topology (2 sockets, 16 cores per socket, so a total of 32 CPUs seen by the kernel) but both virsh -r capabilities and virsh nodeinfo say that the two machines are different - but they really a...

Hello Maybe someone could direct us to right solution with the problem descibed below. We tried different trick bo no success stories. We have a development cluster based on Dell R815 servers (+-30) and a storage server - Netapp FAS 3240 runnig Data Ontap 8.1p2. We have some 100 virtual servers - we use Xen 4.1 for virtualisation. A basics OS is Debian Squeeze with some backports packages (newer kernel, newer xen, newer nfs commons etc) One of virtual servers is a backup serve...

Hi all. I am working for a hosting provider in Poland. We are currently searching for an universal, extensible hardware platform which we would like to use in our server infrastructure. The platform should have: - possibility to install up to 32GB of RAM and at least 4 slots for it; - at least 6 SATA ports; - the possibility to use SAS disks; - at least one 1Gb/s network interface and the

I just put a call into AT&T Office 365 asking them to explain the spoof warning thing... To answer your question.... At the moment, no I can't. I like HPE stuff, we bought a DL380 gen9 say five months ago and totally happy with it. In fairness, its running Server 2012 r2 too but I didn't run into the hardware gotchas I did on the other stuff. It just seems HPE skimped on their lower

I have a Dell R710 which has been flaky for some time. It crashes about once per week. I have literally replaced every piece of hardware in it, and reinstalled Sol 10u9 fresh and clean. I am wondering if other people out there are using Dell hardware, with what degree of success, and in what configuration? The failure seems to be related to the perc 6i. For some period around the time
