Building an On-Site and Off-Size ZFS server, replication question
Good morning. I am in the process of planning a system which will have 2 ZFS servers, one on site, one off site. The on site server will be used by workstations and servers in house, and most of that will stay in house. There will, however, be data i want backed up somewhere else, which is where the offsite server comes in... This server will be sitting in a Data Center and will have some storage

Dedicated server running ESXi with no RAID card, ZFS for storage?
Morning all... I have a Dedicated server in a data center in Germany, and it has 2 3TB drives, but only software RAID. I have got them to install VMWare ESXi and so far everything is going ok... I have the 2 drives as standard data stores... But i am paranoid... So, i installed Nexenta as a VM, gave it a small disk to boot off and 2 1Tb disks on separate physical drives... I have created a

Intel 320 as ZIL?
Are any of you using the Intel 320 as ZIL? It''s MLC based, but I understand its wear and performance characteristics can be bumped up significantly by increasing the overprovisioning to 20% (dropping usable capacity to 80%). Anyone have experience with this? Ray

Performance issues with iSCSI under Linux
Hi!We''re trying to pinpoint our performance issues and we could use all the help to community can provide. We''re running the latest version of Nexenta on a pretty powerful machine (4x Xeon 7550, 256GB RAM, 12x 100GB Samsung SSDs for the cache, 50GB Samsung SSD for the ZIL, 10GbE on a dedicated switch, 11x pairs of 15K HDDs for the pool). We''re connecting a single Linux

slog/L2ARC on a hard drive and not SSD?
Hi, Out of pure curiosity, I was wondering, what would happen if one tries to use a regular 7200RPM (or 10K) drive as slog or L2ARC (or both)? I know these are designed with SSDs in mind, and I know it''s possible to use anything you want as cache. So would ZFS benefit from it? Would it be the same? Would it slow down? I guess it would slow things down, because it would be trying to

ZFS ZIL + L2ARC SSD Setup
I have some questions about the choice of SSDs to use for ZIL and L2ARC. I''m trying to build an OpenSolaris iSCSI SAN out of a whitebox system, which is intended to be used as a backup SAN during storage migration, so it''s built on a tight budget. The system currently has 4GB RAM, 3GHz Core2-Quad and 8x 500GB WD REII SATA HDDs attached to an Areca 8port ARC-1220 controller

(preview) Whitepaper - ZFS Pools Explained - feedback welcome
Hello list, while following this list for more then 1 year, I feel that this list was a great way to get insights into ZFS. Thank you all for contributing. Over the last month''s I was writing a little "whitepaper" trying to consolidate the knowledge collected here. It has now reached a "beta" state and I would like to share the result with you.

Using local disk for cache on an iSCSI zvol...
I''m just wondering if anyone has tried this, and what the performance has been like. Scenario: I''ve got a bunch of v20z machines, with 2 disks. One has the OS on it, and the other is free. As these are disposable client machines, I''m not going to mirror the OS disk. I have a disk server with a striped mirror zpool, carved into a bunch of zvols, each exported via

one ZIL SLOG per zpool?
I have three zpools on a server and want to add a mirrored pair of ssd''s for the ZIL. Can the same pair of SSDs be used for the ZIL of all three zpools or is it one ZIL SLOG device per zpool? -- This message posted from opensolaris.org

zvol wrapped in a vmdk by Virtual Box and double writes?
Hi folks, (Long time no post...) Only starting to get into this one, so apologies if I''m light on detail, but... I have a shiny SSD I''m using to help make some VirtualBox stuff I''m doing go fast. I have a 240GB Intel 520 series jobbie. Nice. I chopped into a few slices - p0 (partition table), p1 128GB, p2 60gb. As part of my work, I have used it both as a RAW

Homegrown Hybrid Storage
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. -

How do separate ZFS filesystems affect performance?
I''m working with a Cyrus IMAP server running on a T2000 box under Solaris 10 10/09 with current patches. Mailboxes reside on six ZFS filesystems, each containing about 200 gigabytes of data. These are part of a single zpool built on four Iscsi devices from our Netapp filer. One of these ZFS filesystems contains a number of global and per-user databases in addition to one sixth of the

Bursty writes - why?
I have a 24 x 1TB system being used as an NFS file server. Seagate SAS disks connected via an LSI 9211-8i SAS controller, disk layout 2 x 11 disk RAIDZ2 + 2 spares. I am using 2 x DDR Drive X1s as the ZIL. When we write anything to it, the writes are always very bursty like this: ool 488K 20.0T 0 0 0 0 xpool 488K 20.0T 0 0 0 0 xpool

dedicated ZIL/L2ARC
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.

ZFS for ISCSI ntfs backing store.
I''m looking to move our file storage from Windows to Opensolaris/zfs. The windows box will be connected through 10g for iscsi to the storage.

Supermicro SAS/SATA controllers?
The standard controller that has been recommended in the past is the AOC-SAT2-MV8 - an 8 port with a marvel chipset. There have been several mentions of LSI based controllers on the mailing lists and I''m wondering about them. One obvious difference is that the Marvel contoller is PCI-X and the LSI controllers are PCI-E. Supermicro have several LSI controllers. AOC-USASLP-L8i with the
