similar to: StorageTek 2540 performance radically changed

Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance.

Hi there I''m busy with some tests on the above hardware and will post some scores soon. For those that do _not_ have the above available for tests, I''m open to suggestions on potential configs that I could run for you. Pop me a mail if you want something specific _or_ you have suggestions concerning filebench (varmail) config setup. Cheers This message posted from

I''m running Postgresql (v8.1.10) on Solaris 10 (Sparc) from within a non-global zone. I originally had the database "storage" in the non-global zone (e.g. /var/local/pgsql/data on a UFS filesystem) and was getting performance of "X" (e.g. from a TPC-like application: http://www.tpc.org). I then wanted to try relocating the database storage from the zone (UFS

Hello, I''m using Xen 3.0 in a Debian Linux Etch / Dell PowerEdge 860 / 4GB RAM / Pentium 4 Dual Core 3Ghz. The machine is using a RAID Controller SAS 5iR, configured with two 500GB disks in RAID-1 (mirroring). I was getting I/O throughput problems, but then I''ve searched the Internet and find a solution saying that I needed to enable the write cache on the RAID controller. Well,

Hi Folks, I've used Samba in the past for Windows NT - Unix connectivity situations. I wondered if Samba also supported AS/400 - Unix connectivity, specifically to allow AS/400 to read/write to a Unix file system...??

Hi all, (down to the wire here on EDU grant pricing :) i''m looking at buying a pair of 7110''s in the EDU grant sale. The price is sure right. I''d use them in a mirrored, cold-failover config. I''d primarily be using them to serve a vmware cluster; the current config is two standalone ESX servers with local storage, 450G of SAS RAID10 each. the 7110 price

Greetings, In looking for inexpensive JBOD and/or RAID solutions to use with ZFS, I''ve run across the recent "VTrak" SAS/SATA systems from Promise Technologies, specifically their E-class and J-class series: E310f FC-connected RAID: http://www.promise.com/product/product_detail_eng.asp?product_id=175 E310s SAS-connected RAID:

[Cross-posting to ldoms-discuss] We are occasionally seeing massive time-to-completions for I/O requests on ZFS file systems on a Sun T5220 attached to a Sun StorageTek 2540 and a Sun J4200, and using a SSD drive as a ZIL device. Primary access to this system is via NFS, and with NFS COMMITs blocking until the request has been sent to disk, performance has been deplorable. The NFS server is a

Hello all, I want to reorganize the virtual disk/ storage pool /volume layout on a StorageTek 6140 with two CSM200 expansion units attached (for example stripe LUNs across trays, which is not the case at the moment). On a data server I have a zpool "pool1" over one of the volumes on the StorageTek. The zfs file systems in the pool are mounted locally and exported via nfs to clients. Now

Hi, I''m running SunOS Release 5.10 Version Generic_118855-36 64-bit and in [b]/etc/system[/b] I put: [b]set zfs:zfs_nocacheflush = 1[/b] And after rebooting, I get the message: [b]sorry, variable ''zfs_nocacheflush'' is not defined in the ''zfs'' module[/b] So is this variable not available in the Solaris kernel? I''m getting really poor

Hey folks, I just went through the archives to see what people are doing for backups, and here is what I found : - amanda - bacula - BackupPC - FreeNAS Here is my situation : we have pretty much all Sun hardware with a Sun StorageTek SL24 tape unit backing it all up. OSes are a combination of RHEL and CentOS. The software we are using is EMC NetWorker Management Console version

Now that we can gather diagnostic info, I think I know why our P2Vs kept failing last week. Another one just died right in front of my eyes. I think either the Ethernet or NFS server at this site occasionally "blips" offline when it gets busy and that messes up P2V migrations. The RHEV export domain is an NFS share offered by an old Storagetek NAS, connected over a 10/100 Ethernet.

I have 2 drives in a Linux 7.1 server , 1 primary and 1 secondary. I am trying to clone to the secondary slave drive and be take the primary out and change the slave to primary and boot from it. The problem I am having is that it the copied drive will not boot, It is not getting the lilo boot and config properly. When I try to boot the copied drive , it boots to a Blank screen with an

Hi, Yesterday I got all my disks in two zpool disconected. They are not real disks - LUNS from StorageTek 2530 array. What could that be - a failing LSI card or a mpt driver in 2009.06? After reboot got four disks in FAILED state - zpool clear fixed things with resilvering. Here is how it started (/var/adm/messages) Feb 23 12:39:03 nexus scsi: [ID 365881 kern.info] /pci at 0,0/pci10de,5d at

To improve the performance of scripts that manipulate zfs snapshots and the zfs snapshot service in perticular there needs to be a way to list all the snapshots for a given object and only the snapshots for that object. There are two RFEs filed that cover this: http://bugs.opensolaris.org/view_bug.do?bug_id=6352014 : ''zfs list'' should have an option to only present direct

Hi, I just noticed that my file server running 2.4.18-pre3 + IDE patches & NTFS patches has this error message in the logs: EXT3-fs error (device md(9,4)): ext3_free_blocks: Freeing blocks not in datazone - block = 33554432, count = 1 This is the only ext3 error I have seen and the uptime is currently over 74 days. The error actually appeared two weeks ago. The timing coincides well with
