similar to: ZFS with Equallogic storage

ZFS fans, I''m preparing some analyses on RAS for large JBOD systems such as the Sun Fire X4500 (aka Thumper). Since there are zillions of possible permutations, I need to limit the analyses to some common or desirable scenarios. Naturally, I''d like your opinions. I''ve already got a few scenarios in analysis, and I don''t want to spoil the brain storming, so

I'm trying to test out an Equallogic PS5500 with a server running CentOS 4.7 I can create a volume and mount it fine using the standard iscsi-initiator-utils tools. The Equallogic box has 3 Gigabit interfaces and I would like to try to set up things so I can read/write from/to the volume using multiple NICs on the server i.e. get 200+ Mbyte/s access to the volume - I've had some

Hi List, Does anyone here use Dell Equallogic IP SAN? If so, do you have any immediate high points / low points you wouldn't mind discussing on- or off-list ? Thanks.

A) Resilver = Defrag. True/false? B) If I buy larger drives and resilver, does defrag happen? C) Does zfs send zfs receive mean it will defrag? -- This message posted from opensolaris.org

We have a Mirror setup in ZFS that''s 73GB (two internal disks on a sun fire v440). We currently are going to attach this system to an Equallogic Box, and will attach an ISCSCI LUN from the Equallogic box to the v440 of about 200gb. The Equallogic Box is configured as a Hardware Raid 50 (two hot spares for redundancy). My question is what''s the best approach to moving the ZFS

Anyone here using the XCP 1.0 Storage EqualLogic has the dell? In Citrix XenServer Xencerter appears to integration, but in XenCenter not with XCP. I read that the drivers were removed. No way around installing the drivers again? Cordialmente, Lorscheider Santiago +55 85 81559040 Msn: lorscheider_santiago@hotmail.com Visite meu blog: http://lsantiago.spaces.live.com Twitter:

I look after an x4500 for a client and wee keep getting drives marked as degraded with just over 20 checksum errors. Most of these errors appear to be driver or hardware related and thier frequency increases during a resilver, which can lead to a death spiral. The increase in errors within a vdev during a resilver (I recently had three drives in an 8 drive raidz vdev "degraded")

I see in NexentaStor''s announcement of Community Edition 3.0.3 they mention some backported patches in this release. Aside from their management features / UI what is the core OS difference if we move to Nexenta from OpenSolaris b134? These DeDup bugs are my main frustration - if a staff member does a rm * in a directory with dedup you can take down the whole storage server - all with

Hello, Has anyone out there been able to qualify the Proliant DL360 G7 for your Solaris/OI/Nexenta environments? Any pros/cons/gotchas (vs. previous generation HP servers) would be greatly appreciated. Thanks in advance! -Anh

Hello everyone, I am currently running Dovecot as a high performance solution to a particular kind of problem. My userbase is small, but it murders email servers. The volume is moderate, but message retention requirements are stringent, to put it nicely. Many users receive a high volume of email traffic, but want to keep every message, and *search* them. This produces mail accounts up to

Hi ZFSers, I''ve been working on merging the Joyent arcstat enhancements with some of my own and am now to the point where it is time to broaden the requirements gathering. The result is to be merged into the illumos tree. arcstat is a perl script to show the value of ARC kstats as they change over time. This is similar to the ideas behind mpstat, iostat, vmstat, and friends. The current

Today, Compellant announced their zNAS addition to their unified storage line. zNAS uses ZFS behind the scenes. http://www.compellent.com/Community/Blog/Posts/2010/4/Compellent-zNAS.aspx Congrats Compellant! -- richard ZFS storage and performance consulting at http://www.RichardElling.com ZFS training on deduplication, NexentaStor, and NAS performance Las Vegas, April 29-30, 2010

Hello list, I posted this a few days ago on opensolaris-discuss@ list I am posting here, because there my be too much noise on other lists I have been without this zfs set for a week now. My main concern at this point,is it even possible to recover this zpool. How does the metadata work? what tool could is use to rebuild the corrupted parts or even find out what parts are corrupted. most but

Hi, I''m looking to build a virtualized web hosting server environment accessing files on a hybrid storage SAN. I was looking at using the Sun X-Fire x4540 with the following configuration: - 6 RAID-Z vdevs with one hot spare each (all 500GB 7200RPM SATA drives) - 2 Intel X-25 32GB SSD''s as a mirrored ZIL - 4 Intel X-25 64GB SSD''s as the L2ARC. -

Hello, I''d like to be able to create a windows DomU which is to be stored on a NAS (Equallogic) device. I was wondering if anyone has any best practices on how to do this? Is there a way to extend the DomU C drive once you create the initial device, etc? Any suggestions would be great. I have already tried this by just using a phy:/dev/path-to-iscsi-mount- point and it appears to

Hi. I''d like to request a feature be added to zfs. Currently, on SAN attached disk, zpool shows up with a big WWN for the disk. If ZFS (or the zpool command, in particular) had a text field for arbitrary information, it would be possible to add something that would indicate what LUN on what array the disk in question might be. This would make troubleshooting and general

This is a hypothetical question that could actually happen: Suppose a root pool is a mirror of c0t0d0s0 and c0t1d0s0 and for some reason c0t0d0s0 goes off line, but comes back on line after a shutdown. The primary boot disk would then be c0t0d0s0 which would have much older data than c0t1d0s0. Under normal circumstances ZFS would know that c0t0d0s0 needs to be resilvered. But in this case

We are looking into the possibility of adding a dedicated ZIL and/or L2ARC devices to our pool. We are looking into getting 4 ? 32GB Intel X25-E SSD drives. Would this be a good solution to slow write speeds? We are currently sharing out different slices of the pool to windows servers using comstar and fibrechannel. We are currently getting around 300MB/sec performance with 70-100% disk busy.

Hi folks, Myself and a colleague are currently involved in a prototyping exercise to evaluate ZFS against our current filesystem. We are looking at the best way to arrange the disks in a 3510 storage array. We have been testing with the 12 disks on the 3510 exported as "nraid" logical devices. We then configured a single ZFS pool on top of this, using two raid-z arrays. We are getting

Heya all, I''m working on testing ZFS with NFS, and I could use some guidance - read speeds are a bit less than I expected. Over a gig-e line, we''re seeing ~30 MB/s reads on average - doesn''t seem to matter if we''re doing large numbers of small files or small numbers of large files, the speed seems to top out there. We''ve disabled pre-fetching, which
