I have a Dell PowerEdge 2950 and am looking to add more storage. I know a lot of factors can go into the type of answer given, but for present and future technology planning, should I look for a rack of SATA, SCSI, or fibre channel drives? Maybe I'm dating myself with fibre channel, and possibly SCSI? I may be looking to add a few TB now, and possibly more later. What are people

Hi All, just a quick question I could not figure out. Is there a way to export a PCI device to multiple VMs (para) keeping it available to dom0? Xen version is 3.0.4. Thanks, Jan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

We have a setup with 15 hosts fibre attached via a switch to a common SAN. Each host has a single fibre port, the SAN has two controllers each with two ports. The SAN is exposing four OCFS2 v1.4.2 volumes. While performing a failover test, we observed 8 hosts fence and 2 reboot _without_ fencing. The OCFS2 FAQ recommends a default disk heartbeat of 31 - 61 loops for multipath io users. Our initial

I have added a specification of probes for the fibre channel COMSTAR port provider to the DTrace section of wikis.sun.com. The proposal may be found here: http://wikis.sun.com/display/DTrace/fibre+channel+Provider I welcome feedback regarding this proposal. Thanks, Sam

I am wondering if any one knows of a way to manage Xyratex disk shelves from CentOS (in particular CentOS 4). More details: Some years ago I installed a NAS unit from Exanet which consists of 2 rebadged IBM x3650 head nodes and a couple of Xyratex disk shelves with a total of 96 TB of raw disk, connected by fibre channel. The operating system is based on CentOS 4.4, but is modified, and runs a

Please reply to david.curtis at sun.com ******** Background / configuration ************** zpool will not create a storage pool on fibre channel storage. I''m attached to an IBM SVC using the IBMsdd driver. I have no problem using SVM metadevices and UFS on these devices. List steps to reproduce the problem(if applicable): Build Solaris 10 Update 2 server Attach to an external

Hello again. Our production cluster has begun experiencing some vicious slowdowns that may (or may not) be related to the filesystems. When the problem occurs, the load average on the servers jumps up to 30 or higher. Usually one node will climb while the other drops, then they will switch places a few minutes later. At one point, we had one node's load average up over 300. Our site

For quite some time I?ve been using FreeNAS to provide services as a NAS over ethernet and SAN over Fibre Channel to CentOS 7 servers each using their own export, not sharing the same one. It?s time for me to replace my hardware and I have a new R720XD that I?d like to use in the same capacity but configure CentOS 7 as a Fibre Channel target rather than use FreeNAS any further. I?m doing

Hi, I created an HVM type virtual machine and installed RHEL5U7 guest in it. I have assigned 7 scsi disks to the virtual machine in physical mode (using phy:), however, I see those disks are xvd and not as scsi. Is anyone aware what the problem might be ? Please let me know what kind of information do I need to post in order to narrow down to the problem. Thanks, K

Hello, I received the following question from a company I am working with: We are having issues with our early experiments with ZFS with volumes mounted from a 6130. Here is what we have and what we are seeing: T2000 (geronimo) on the fibre with a 6130. 6130 configured with UFS volumes mapped and mounted on several other hosts. it''s the only host using ZFS volume (only

Hi, I just deploy the ZFS on an SAN attach disk array and it''s working fine. How do i get dual pathing advantage of the disk ( like DMP in Veritas). Can someone point to correct doc and setup. Thanks in Advance. Rgds Vikash Gupta This message posted from opensolaris.org

Hi there Is it fair to compare the 2 solutions using Solaris 10 U2 and a commercial database (SAP SD scenario). The cache on the HW raid helps, and the CPU load is less... but the solution costs more and you _might_ not need the performance of the HW RAID. Has anybody with access to these units done a benchmark comparing the performance (and with the pricelist in hand) came to a conclusion.

I had this exact same problem with 2.0.7. I had done a little investigation and found scheduled_work gets called to schedule the shutdown in the user domain kernel, but the shutdown work that gets scheduled never actually gets called. I''m glad someone else is seeing this same problem now :-) Like you, it worked a number of times in a row, then would fail, and it didn''t seem to

Hi, I need to migrate about 8Tb of data from a Mac Fibre Channel RAID to by LVM Ext3 Linux Fibre Channel RAID. For speed I planned to connect both RAID's to my CentOS Server and copy the data directly. The Mac volume is formatted as Mac OS Extended (Journaled) it seems that CentOS 5.4 supports reading HFS volumes but not HFSPlus volumes. Is there a way of getting this volume to mount so I

Hi All, I've a single 1.2.17 Asterisk system. Gradwell here in the UK is used for PSTN calls via IAX2. Our 'net link is a dedicated 2Mb fibre connection (of which we have ever used 50% max bandwidth). We've no E1/T1 links, everything is IP based. My boss complains that many of the calls he holds with others has a bad quality. He also says that its not just him. My iax.conf file

Hello, Anyone using or tested Oracle (OLTP load) on NetApp? Connected via Fibre Channel not NFS. Performance is good or should we better stay with "classic" SAN storage like HP EVA or similar boxes from EMC or Hitachi? In EMC test papers NetApp does not look good. In NetApp papers - vice versa. :) So I'm somewhat confused. I remember someone in this list saying that

Howdy all, We're experiencing terrible small file performance when copying or moving files on gluster clients. In the example below, Gluster is taking 6mins~ to copy 128MB / 21,000 files sideways on a client, doing the same thing on NFS (which I know is a totally different solution etc. etc.) takes approximately 10-15 seconds(!). Any advice for tuning the volume or XFS settings would be
