Dilbert As gently caress posted:Ehh vMotion can chew up some poo poo when you throw it into maintenance mode, especially if it's running view Yea, but as you said, you can control that with NIOC so have methods of keeping vMotion from eating up all of your bandwidth. A single vMotion only requires 250 Mbs, or about 1/40th the bandwidth of a 10GbE link, and even then it only requires it for a very brief period. You can also set the number of concurrent vmotions such that they won't come anywhere near saturating the link. If your hosts take somewhat longer to go into maintenance mode it isn't really the end of the world. Especially given that even limiting vMotion traffic to a 1/4th a 10GbE link and limiting the rest for storage will still provide more bandwidth than a 1GbE link. We have about 600 ESX hosts and all of them run everything other than ILO over dual 10GbE links to Nexus 7k and 5k switches in a vPC. Never had any issues with link saturation.

Don't see a network topology but I'll assume the ESXi servers and storage are plugged into the same physical switch? People shouldn't be messing about with your training infrastructure and I'm not sure what "VDS becomes corrupt" means. Just keep your management interfaces on a standard vSwitch and you should be otherwise set. That said it sounds like you're throwing a lot of engineering at this problem with potentially questionable benefit. For example on NFS you're probably not going to see more than 1 gig of throughput on any given ESXi host unless you do some trickery using multiple subnets and multiple volumes and evenly distribute your virtual machines over those volumes. NetApp TR-3749 I think covers this implementation in some detail should you choose to go down that route. It's a netapp paper but the theory applies universally using any NFS system. Are you actually driving that much traffic to the storage? What are you measuring with? What determines if a workload is running on iSCSI vs NFS?

Finance has some new servers running a memory intensive OLAP server (TM1) and performance isn't where they want to be. Now starts the fight between infrastructure(my team), applications, and vendor on why performance is not up to snuff. Application and vendor don't understand VMware so they blame us. I'm 95% sure our VMware environment is setup optimally. ESXi 5.1u2 running on DL360p G8 w/ dual E5-2690's and 384GB RAM. Their main VM is running 4vCPU with 64GB RAM and none of the performance counters anywhere come close to showing a heavy load.

If I can't get it to work I'll just throw in a NIC that's on the HCL. Thanks for pointing me in the right direction. If I get it to work I might try to repeat the process using the powerCLI too.

adorai posted:If you are confident that it's not your SAN/Network/Hosts then stand firm. In my experience, 95% of the time the application runs like poo poo it's because of a poorly written query. On more than one occasion it has been a query in a stored procedure that the application vendor knew was lovely, normally updates, and forgot to do on our install. I want to 2nd this. If they say something is wrong with your infrastructure ask them what exactly they think is wrong and you'll be happy to look at it. If you want to up the ante ask to see their queries. If it's a commercial DB like Oracle there are TONS of build in tools for query and performance analysis. I worked at a Big Corp where a mess of lovely perl scripts and poorly written SQL queries brought an AIX box with 32 CPUs, 128g of RAM, and 8x 4g HBAs to it's knees. When we tried to call them out on it and asked for read-only access to the Oracle performance tools they wouldn't give it to us. I worked at another Big Corp where people didn't know that multi-threading was something you program at the application level and tried to blame the OS guys for "not allowing the application to run on more than 1 CPU." Also remember that with regard to hardware the application vendor has no skin in the game. It's easy for them to say "yeah we need 32g of RAM" because they don't know how to size their own app and they aren't the ones who are paying for the hardware but it will cost them manhours to fix their poo poo.

Pantology posted:Was pulling that from this. I still parse "Linux" as "Here be dragons," so I'm not sure why they can't make the supported Red Hat client work nice with SLES. Different library versions. OSX and Windows both generally ship with every library they need (hence winsxs, osx .apps being directory trees with libs). It's possible to do this on Linux, shove all your poo poo into some directory and use that, but it's considered bad practice. So if RHEL has libfoo.1.2.3 and SLES has libfoo.1.2.4, you need to recompile (or at least relink) against the new version. Vendors don't like doing this, which is why they (IBM, Oracle, etc) generally just support RHEL and SLES (Ubuntu, fedora, Debian, and others move too fast or don't guarantee ABIs/APIs will stay the same for a given major release). Still not sure why VMware won't approve it. It's probably "we haven't tested this, and the license on the driver prevents us from shipping it, so it might work, but you're on your own in an unsupported configuration if you do it"

Riso posted:And people accuse Windows of DLL hell. They haven't ever seen Linux library shenanigans. Linux doesn't actually have library shenanigans in that sense. "DLL hell" wasn't an empty accusation. Early versions of NT (and all of 9x) shoved everything in system32, tried to save memory by loading the same DLL, and assemblies didn't specify versions, so when Windows updated foo.dll or some application installed a different version of bar.dll, it potentially broke everything which linked against it. Build systems are good about saying "libfoo updated to a new version which breaks compatibility? Rebuild everything that touches it". RHEL and SLES only break that compatibility on major versions. If you're seeing " library shenanigans ", you may be doing it wrong.

Except RHEL 6.5 which ships with backward-incompatible libs for OpenSSL in direct contradiction of Red Hat's policy as far as I can tell Most of our boxes are still on 6.4 because of ~reasons~ and it's getting increasingly harder to find packages that will install on them because people have been rebuilding them against the newer libssl/libcrypto. On the bright side, CentOS 6.4 wasn't vulnerable to Heartbleed so that made that week suck a lot less for me.

Need some advice: I've got 3 hosts each with single quad port 1gbit NIC and 1 dual port 10Gbit NIC. In the same rack there are 3 1Gbit 48 port switches (per switch has 2Gbit uplink to our core switch), and in another nearby rack I have two Cisco Cat 4500-X switches (each with 20Gbit uplink to our Core switch). At the switching layer we don't have anything too advanced (I can't even create cross-switch Port Channels (eg virtual port channel)). My qeustion is this: When you only have 2 10Gbit ports to use, how do you load balance/make those links redundant when you can't use port channel?

This isn't a problem, I need the practice, but I was hoping to get it working today. I have a question about my plan. My host is on the work network. That way I can access it from my work desktop. All the VMs are on a second network that leads to a second network port that will connect to my test view clients. That keeps me from making a mess out of real stuff. V-center is my weird one. It needs to be on the work network to see the host, right? But at some point the View server will want to see the vcenter server if I understand correctly. Does it automagically do it through VMware tools or will it want an IP I'm already working on adding a second network card onto the vcenter app. Right now I'm trying to do it with a thing called YAST. Does this sound about right for now? Edit: Hey... I don't get errors for eth1 in the vcenter network screen anymore. I think I got it! I wish I'd checked before hitting post.

Wicaeed posted:I thought DVS (Distributed Virtual Switch) was an Enterprise only feature Somehow I read your post as Enterprise instead of essentials What you can do is put two vSwithes on those 10G interfaces and limit the outbound traffic. So you can set ISCSI/NFS to XXXXXXX@Kbps/s, vMotion @XXXXXXX@Kbps/s, management XXX@Kbps/s, and use your QP for additional failback. You may not have access to NIOC, but ratelimiting the egress traffic on all hosts is a good way to do a cheap NIOC. I'd probably segregate your vmotion though, that thing is a monster for bandwidth.
