I''m setting up a two-node cluster with 1U x86 servers. It needs a small amount of shared storage, with two or four disks. I understand that the J4200 with SAS disks is approved for this use, although I haven''t seen this information in writing. Does anyone have experience with this sort of configuration? I have a few questions. I understand that the J4200 with SATA disks will not do SCSI reservations. Will it with SAS disks? The X41...

apparently if you don''t order a J4200 with drives, you just get filler sleds that won''t accept a hard drive. (had to look at a parts breakdown on sunsolve to figure this out -- the docs should simply make this clear.) it looks like the sled that will accept a drive is part #570-1182. anyone know how i could order 12 of these...

[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 LDOM domain on the T5220. To give an idea of how bad the situation is, iotop from the DTra...

I am helping a friend who is build a storage server for his company and I have advocated for Solaris and ZFS. But now we are having trouble to find any good SATA controller for 12+ disks, there are Areca cards, but they seems very flaky (24 port support, but hangs with more than 12 in JBOD mode, hangs on disk failures etc). The AOC-SAT2-MV8,AOC-USAS-L8i have been mentioned, but it had

We have three of these HBA''s, used as follows: X4150, J4400, Solaris-10U7-x86, mpt patch 141737-01 V245, J4200, Solaris-10U7, mpt patch 141736-05 X4170, J4400, Solaris-10U8-x86, mpt/kernel patch 141445-09 None of these systems are suffering the issues you describe. All of their SAS HBA''s are running the latest Sun-supported firmware I could find for these HBA''s, which is v1.26.03.00 (BI...

Hello! Our company have 2 sun 7110 with the following configuration: Primary: 7110 with 2 qc 1.9ghz HE opterons and 32GB ram 16 2.5" 10Krpm sas disc (2 system, 1 spare) a pool is configured from the rest so we have 13 active working discs in raidz-2 (called main) there is a sun J4200 jbod connected to this device with 12x750GB discs with 1 spare and 11active discs there is another pool configured (called JBOD) Backup: 7110 (converted from x4240) with 2 qc 1.9ghz HE opterons and 8GB ram 16 2.5" 10Krpm sas disc (2 system, 1 spare) a pool is configured from the rest so we ha...

Dear all Sorry if it''s kind of off-topic for the list but after talking to lots of vendors I''m running out of ideas... We are looking for JBOD systems which (1) hold 20+ 3.3" SATA drives (2) are rack mountable (3) have all the nive hot-swap stuff (4) allow 2 hosts to connect via SAS (4+ lines per host) and see all available drives as disks, no RAID volume. In a

Hello list, someone (actually neil perrin (CC)) mentioned in this thread: http://mail.opensolaris.org/pipermail/zfs-discuss/2009-December/034340.html that is should be possible to import a pool with failed log devices (with or without data loss ?). >/ />/ Has the following error no consequences? />/ />/ Bug ID 6538021 />/ Synopsis Need a way to force pool startup when

We are looking at adding to our storage. We would like ~20TB-30 TB. we have ~ 200 nodes (1100 cores) to feed data to using nfs, and we are looking for high reliability, good performance (up to at least 350 MBytes /second over 10 GigE connection) and large capacity. For the X45xx (aka thumper) capacity and performanance seem to be there (we have 3 now) However, for system upgrades , maintenance

Hey folks, I guess this is an odd question to be asking here, but I could do with some feedback from anybody who''s actually using ZFS in anger. I''m about to go live with ZFS in our company on a new fileserver, but I have some real concerns about whether I can really trust ZFS to keep my data alive if things go wrong. This is a big step for us, we''re a 100% windows

While I understand everything at Oracle is "top secret" these days. Does anyone have any insight into a next-gen X4500 / X4540? Does some other Oracle / Sun partner make a comparable system that is fully supported by Oracle / Sun? http://www.oracle.com/us/products/servers-storage/servers/previous-products/index.html What do X4500 / X4540 owners use if they''d like more

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
