[zfs-discuss] PowerEdge R510 with PERC H200/H700 with ZFS
Anyone have any experience with a R510 with the PERC H200/H700 controller with ZFS? My perception is that Dell doesn't play well with OpenSolaris. Thanks, Geoff ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

It is funny how sometimes one forms these views as you gather information. Geoff It is just that lots of the PERC controllers do not do JBOD very well. I've done it several times making a RAID 0 for each drive. Unfortunately, that means the server has lots of RAID hardware that is not utilized very well. Also, ZFS loves to see lots of spindles, and Dell boxes tend not to have lots of drive bays in comparison to what you can build at a given price point. Of course then you have warranty / service issues to consider. -- Terry Hull Network Resource Group, Inc. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

It seems the R510 can have up to 12 spindles. The online configurator only allows you to select SLC SSDs, which are a lot more expensive than the MLC versions. It would be nice to do MLC since that works fine for L2ARC. I believe they have an onboard SD flash connector too. It would be great to be able to install the base OS onto a flash card and not waste two drives. Are you using the Broadcom or Intel NICs? For sure the benefit of buying name brand is the warranty/service side of things, which is important to me. I don't want to spend any time worrying/fixing boxes. I understand that one. I have been using both Intel and Broadcom NICs successfully. My gut tells me I like the Intel better, but I can't say that is because I have had trouble with the Broadcom. It is just a personal preference that I probably can't justify. -- Terry ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] zpool 'stuck' after failed zvol destory and reboot
- Original Message - It's alive!! Some 20 hours after starting, the zpool import finished, and all data is alive well. I ordered the extra RAM, so that'll no doubt help in the future. I'm also in the process of de-Xen'ing the server I had running under xVM, so Solaris will get the whole 8GB to itself. Finally, I turned off compression dedup on all the datasets, used zfs send to dump them to a clean pool that hasn't and won't see dedup. Lesson learned on dedup... Toy home servers need not apply. =) Compression is safe, though Vennlige hilsener / Best regards roy -- Roy Sigurd Karlsbakk (+47) 97542685 r...@karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.

Re: [zfs-discuss] problem with zpool import - zil and cache drive are not displayed?
zpool import -fF -R / tank As above victor managed to mock up a log device and get the pool to a state where it could be imported again. Awesome stuff. I'm also interested in how if its not too complex. :) Unfortunately though it looks like something is still not quite right. Even though running zpool import -fR / tank seems to suggest it is going to recovery and loose 91 seconds when i actually run the command zpool import -fF -R / tank the machine locks up and reboots. I've tried this multiple times with the same results. h. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] PowerEdge R510 with PERC H200/H700 with ZFS
I've been running OpenSolaris on my Dell Precision Workstation T7500 for 9 months, and it works great. It's my default desktop operating system, and I've had zero problems with hardware compatibility. I also have installed EON 0.600 on my Dell PowerEdge T410 (not so different from your R510). A few words of caution: 1. Beware of the onboard controllers. The RAID controller on that motherboard only works in Windows; neither Linux nor OpenSolaris can recognize drives attached to it at all. So I was stuck running in ATA mode at the beginning, which is awful in terms of performance. 2. I'd also recommend avoiding the PERC cards, in particular since it makes drives attached to it impossible to transport to another system. Instead, I use the SAS 6i/R controller. That's built into the motherboard on the PW T7500, and I got one separately for the PE T410. That works well, and is completely fine with OpenSolaris. I'd recommend those, because then you can be sure to get the cabling from Dell (which in the case of the PowerEdge, was completely nonstandard). And if the card fails, they'll replace it ASAP, which isn't necessarily the case with other vendors' cards. So aside from the RAID controller and cabling issues on the PE T410, I've had nothing but good experiences in terms of Dell Precision workstations and PowerEdge servers, running OpenSolaris. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
