Twinax cable requirement is also listed on that page.quote:What are the SFP+ direct attach cable requirements for the Intel® Ethernet Server Adapter Series? Note that last bit as we got burned by it on the X520s. To use a 10m active cable, you have to have the windows-based intel software installed or you get some very weird symptoms. We tried it on ESX and had to back off to 5m cables. The 10m active cables work fine with QLE8242s.

http://www.wired.com/wiredenterprise/2012/04/nicira/ TL;DR: Company in California is developing network virtualization software that moves forward/filtering decisions from switches and packet routing/access control functions from routers up to the application layer. The capabilities will apparently go well beyond vSwitch.

VMware Experts, My employer is looking for someone knowledgeable in VMware and storage to help us with our current ESX infrastructure while we wait to fill the position outlined in this post here. If any of you in the NYC area are interested, please PM me or email me at cesworthy at Google's email service for more details. I promise there's nothing horrifying or alcoholism inducing involved; we just want a more experienced set of eyes to look at what we have and give us some guidance about how to move forward. Thanks!

I'm running vmware essentials (4.1) Is there an easy way to monitor the IOPS being use by individual VMs in an ESXi setup? something that will show average and peak or better some sort of high utilization average metric. (someway to filter out the spikes and nighttime when the box isn't doing anything) Basically I have a dell r610 with 4x300 SAS in Raid10 with two hosts and I want to make sure one host get's at least 50% of the IOPS so i'd like to throttle down the other so it maxes out at around 50% Also does anyone have any experience with something like the thecus 8900 and or the QNAP 879 as a iSCSI NAS for lower utilization VMs or VM Drives?

I'm in the process of upgrading to something else, but I've been using a Thecus N8800+ for the last year and a half and it's been decent. Seems like the N8900 is the next generation of that? The bang for the buck is definitely there, you can have acceptable shared storage for a small environment for a couple grand. It's not super feature rich, and the interface is pretty bad and littered with "Engrish", but it's been rock solid stability wise. Performance has been poor, but I only have 7200 RPM SATA drives in there so I don't expect it to scream. By which I mean day-to-day usage is totally fine, but something like shuffling VMDK files between LUNs takes many hours even though they are on the same drat physical device. I've never had something nicer so I don't know how typical that is.

I have a synology ds1010 that I use as a backup target for backup exec which is great except the backexec part), but even a relatively low requirements win 7 VM was too slow to bother with. What did setting up the QNAPs properly consist of?

I should add that most everything I've virtualized so far has been Linux boxes whose physical hardware sat at like 0.05 load average. I run vCenter in a VM and ironically it's probably the most demanding thing on there. I'm virtualizing for VMware's HA features more than anything; running a couple newer ESXi hosts in a cluster has proven infinitely better than having old garbage homebuilt boxes go down monthly because a CPU fan died or whatever. The Thecus was a champ for what I needed (proving virtualization to management) and now I can work on getting better storage in there and virtualizing apps that couldn't easily be running in the background on a laptop. And I admit to knowing little about "serious" storage, though I'm reading and testing in the lab every single day. As the only sysadmin in the company and not having major storage needs, it just hasn't been top priority.

bob arctor posted:What are you upgrading to? It sucks We are. iSCSI for all of them. They started out as our primary shared storage for VMs, and we are slowly migrating now to two Dell MD3220i (two separate clusters). Performance isn't anything to write home about, but between the four units, we are running around 45 VMs without any major complaints (nothing extremely IO intensive). My old boss had the networking to "Port Trunking" with Balance-rr (Round-Robin). When we had this enabled, it would cap our throughput at around 10 megs. Switching to Balance XOR brought us to around 110 megs. Never had any huge issues. They do have alot of FW updates, so make sure you update to something recent (the newest for us had issues, so we are one version back (3.6)). We have also just started using Veeam to do backups of all our VMs, which is also being stored on these. No problems with that either. My one complaint on these (809u) is that they do not support jumbo frames. And also you cannot add in 10gb networking. We purchased a 1079 to test with, which does support 10gb, so moving forward for cheap shared storage, we may go with those.

Could someone help me out with a little clarification on how vNICs and vSwitch's interact with one another please? Say I have a vSwitch and I have a pair of VMs each with a vNIC connected to the vSwitch. Ignoring any OS limitations, what is the maximum throughput I could get between the two servers via their vNICs since the traffic is all within the same vSwitch please? I'm assuming the type/model of vNIC plays a part but I've never been 100% clear on the differences - AIUI Flexible and E1000 are 1gbps and VMXNET is 10gbps?

Misogynist posted:Ignore the speed reported to the OS, it's not relevant to anything. Any of the emulated vNICs (E1000, etc.) will perform as quickly as the server can emulate them, but the server will run them through the vSwitch. The paravirtualized vNICs communicate directly with the hypervisor, and in the case of VMXNET3, can ferry data between VMs at the speed of shared memory. Thanks for the reply. This is what's not so clear to me so far. So if I use, say, an E1000, you're saying the OS might report a 1gbps NIC but it can actually transfer data in/out of the vSwitch at greater than 1gbps? I'm assuming by the time I get to using vSphere for the application I have in mind that some issue I read of with the VMXNET driver when used with that application will have been ironed out, and I'll have 10gbps pNIC connectivity in/out of the vSwitch, I just wasn't clear how the intra-vSwitch traffic works..

Performance isn't anything to write home about, but between the four units, we are running around 45 VMs without any major complaints (nothing extremely IO intensive). I guess what I'm trying to figure out is if it's worth the extra bucks for an QNAP 879 over an 859 or a thecus N8900 over an 8900V given that the next step up seems to be something like the dell md3220i type thing which is out of my budget and since we only run a couple of hosts and 6-8 VMs two of which are high I/O and will need to stay on local storage anyway. Another couple quick host storage questions: For a dell 610 with 6X SAS is RAID6 the most desirable drive config? I have a 610 with 4 drives in RAID10? How much performance is lost to ESXi (4.1) with local drives over running the OS on bare metal?

Once we replaced them with some managed wire speed switches (Dell 5548, and now switching to 6248) they seemed to fine.

It doesn't even make sense to me. The E1000 is an emulated 1Gb Intel NIC, I don't see how it could go faster. In my mind the only reason to not use the VMXNET3 interface is for driver/compatibility issues. Rhymenoserous posted:I have this sudden desire to test this. Using iperf between two of my VMs with VMXNET3 adapters gets me around 9Gb/s.

Noob question: I installed ESXi(?) on a spare server and used VMware standalone converter to convert a physical laptop to a VM on the ESXi server. I want to make another "instance" of that VM, is that possible? Can I just copy the one I already converted or do I have to re-convert the same laptop again (which took over 3 days)?
