The 10cm blower in this chassis is pretty loud and is said to cause disk problems because of the vibrations. All new chassis by SM have 2 of 3 40mm fans instead. I've had good luck with those, and they also seem a bit more quiet.

Turned out, knock on wood, that the head parking of the green drives was the cullprit after all. I had the timer well beyond the normal 8 seconds but only turning it off (-d) with the open idle3 tool fixed most of the errors. Seems stable now.

Depending on what you are going to use them for the WD Red model line seems pretty popular right now as a newcomer to the NAS market. For a single disk as an upgrade i would certainly look at 1tb platter disks.

Hiya. For the past few weeks i've been scratching my head on this one. I have a LSI 1068e with the p21 IT firmware on it, and a SASx28 expander to a bunch of wd20earx and ears drives. Now all disks hooked up directly to the controller works fine with heavy loads. With all drives in the chassis...

If it's a single range, nmap would be pretty easy for a ping sweep.

If you do not already own another 7770, i see no point in getting a crossfire setup with midrange cards. Can't you get, guaranteed, higher performance with a more expensive card in a single setup?

GNS3 is a pretty straight forward tool to get a virtual networking equipment running. Ya can even bridge a nic to them to connect to physical boxes. You do need the right images if you want to do all CCNP stuff.

Don't confuse the s775 core2's with the s771 xeon's, or s775 xeons for that matter. 771 was the higher end platform that could do multi socket.

I'm not sure what kind of batteries those are but keep in mind to ventilate them!

There's nothing you really can't do with USB (yet withlimited bandwidth).

ESXi is not the end of the world. There is KVM, Xen and a few other alternatives that rely on standard drivers from the kernel instead of the small database by vmware.

Match an extended acl to citrix on a route map?

Thought i would post my findings on this matter. Contacted Supermicro, who were very fast to help me out with this one. They've sent me a different bios that was not available for download publicly and that fixed the ECC reporting. 2.0a.

Howdy. Got a X7SBL-ln2 (old girl) with a q6600 that is meant to go on server duty for a few more years. Got 4 udimms that are on the supported memory list and somehow ECC shows disabled in memtest and a linux livecd (checked with dmesg | grep EDAC and dmidecode --type memory). From my...

I could see a use with quad nics to assign 2 interfaces to a router VM and use the rest for iscsi traffic or whatnot. It would save pci-e lanes which could become few in small builds with HBAs, nics and whatever.

Vt-d was introduced with the q35 chipset and like i said, untill nehalem it wasn''t cpu dependend. Although not officially supported i'm pretty sure that it will work fine.

For a business enviroment i think they're alright. It might take you a few minutes to get used to it as it does have its drawbacks in config-ability but other than that i think its pretty solid. Nice integration with adds also. I never bothered with the NIS part of TMG though.

I was under the impression that the older generations handled all vt-d stuff in the chipset. I haven''t tried it myself but if it works on a q6600, which it shouldnt work with officially (right?) then why not.

Please keep in mind that you can't use Registered ECC memory on the 1155 platform. Regular ECC, or Unbuffered ECC is a bit more expensive unless going the 4 x 4gb route.

There really is no need to put the hypervisor on the ssd. In case of esx(i) there is no trim (although it is not needed as much with some ssd's) and also no benefit as everything is loaded in a ramdrive and only logs and settings are written back. An VMFS partitioned drive will work on other...

Does everything start up right away? Reboot the box after you're done with auto-login. It's a poormens solution, no idea if it's possible to script something to re-connect the console session.

Raid 5 has been proven ancient for drives this big. Rebuild times on these disks with parity-raid will take a long time and the chance of corruption because of w/e are quite big with 4 disks from the same batch. Raid6 would be better but with only 4 disks i would go raid 1+0, far lower rebuild...

I'm not really sure but from a bit of research it seems the Xeon e5's are in the same boat as the e3's when it comes to memory support, Only unbuffered ecc memory? Would be a shame as the 8gb udimms havent dropped in price a whole lot after about a year that the e3 xeon is on the market.

That's something i'm not entirely sure about either. All motherboards i've seen to date only state support till 64gb though, im sure thats a limitation of using unbuffered RAM as 32gb was the max addressable by the last, dual channel, generation.

Won't the x79 take registered ECC dimms (with a xeon 1620) which are like 10 times cheaper? You could get 64 gb of RAM for half the price of 32 gb's of unbuffered ecc dimms. Sure, it won't run ESXi free but there are a bunch of hypervisors that would run just as well. s2011 made me skip the...

It's probably a WD green, they park the heads every once in a while. Easy fix with wddidle.exe from freedos, set it at a high value or complete disable if you expect (or need) these drives to be ready at all times or manually spin them down.

There might be a slight difference in clock speed, the non-throttled clock speed is a bit higher on the 3820. I don't know how these idle measurements are calculated or measured but i guess thats it. Cores don't really matter when it comes to idle power usage it seems, look at the i3 and i5...

Very cool stuff you are trying over there. I've been thinking of doing something like that myself. If you decide to post more about your progress I would be happy to read about it.

That's something I did before with no effect. I will however try that out as soon as it fails to boot again.

Thanks for your replies. I started up good 'ol furmark and it wouldn't budge to 2.0 or 2.1. I will do some more testing and rebooting later tonight to see if it changes. With the cpus nowadays dealing with the pci-e lanes it could be true that the cpu hsf is the culprit indeed. It's a...

G'day, Having some ongoing issues with my Asus p8p67 motherboard. When I got all of it with a 6950 it wouldn't boot, the beeps (long-short-short-short) told me it was a vga error. Tried the card in another computer and it worked just fine. Tried a 5850 next and this one worked just fine too. Oh...

I have seen graphs of an idle diskless setup with an e3 @ 20 watts in a review. As for the Intel boards, don't they have vPro? The newest AMT features ip kvm in the OS right? My dq45 with vPro has the KVM till the os boots (esxi) and i never really looked into it any further as it's at home...

I set up this script to backup my VM's every night; http://communities.vmware.com/docs/DOC-8760 It's GhettoVCB and with a cron you can let it run every night and send you an email to verify completion or show any errors that might've popped up.

IF i'm not mistaking, the full-atx 1155 motherboards by Supermicro aren't very picky about what sort of RAM they get. The udimms currently on ebay for 210 or so are told to work with those boards, perhaps that's something to take a look at. Still pricy though, could have HA and all with two i3...

Sorry, but the memory you linked is an 8x4 kit. Udimms for the 1155 platform are still a pain to afford. The kits on ebay used to be 200 bucks for 2x8 i believe, but these were only offerd this month and the price was raised the last time i checked. I really would love to get me an E3 esxi...

You may want to troubleshoot your internal network and connectivity instead of trying to download and see if they are succesfull or not. If you have another client somewhere in your network, set up a share and transfer some big files. I'm sure there are scripts out there to test and strain...

I figure that they wouldn't want to rebadge a switch that didn't live up to the expectations of the regular HP stuff I wonder if the buffer of the 1910 is sufficient for jumbo's because it would be one of the few in it's pricerange. Right? :confused:

I'm looking forward to your review as I'm thinking about getting one too. Not much more expensive than a second hand switch without warranty and perhaps a chitload of problems. Would love to see performance with iscsi and aggregate links.

I am aware of the network requirements and limitations of nic teaming, trust me I didnt expect it to just work ;). With round robin for instance its possible to load balance iscsi traffic between esx and storage, on a dedicated vlan ofcourse. It's a poormens solution in many ways but 10gbit...

G'day [H] Network and server overhaul is around the corner, just planning the changes that will fit my budget for now. At the moment my esx box is taking all the hits as a test mule, storage, webserver and everything you can imagine running on it. Far from ideal which made me rethink my...
