I'm running ESXI on a HP Microserver with another Microserver as a NAS/ISCSI host, NFS Datastores work great, I can max out the link easily. but iSCSI doesn't seem to work too well and I was hoping someone could tell me why? Even with MPIO set to round robin I get 70MB/s read off my raid array which does 300MB/s locally on the nas. Regardless of whether I'm using 2 paths or 1 to the iSCSI host the performance is terrible. If I connect the luns using the windows iscsi initiator the performance is great, it will max out the link easily and there are no issues. Is there something I need to be doing to get better performance out of iscsi targets on ESXI 5?

How can I add the ability to my vSphere cluster for switch port ACL's on the networks? It looks like VShield App has been discontinued, Cisco's 1000v looks like it should do it but needs to be managed by people other than our network engineers. :edit: it looks like vSphere 5.5 adds this functionality, no idea when that is coming out though. theperminator fucked around with this message at 06:56 on Sep 4, 2013 |

I don't think you can run OSX under ESXI on a mac anyway, it requires the hypervisor to virtualise access to the hardware TPM in a mac, so you might need to use fakesmc.kext to get it to work

Has anyone had any issues with vMotioning a Database? In all the years I've been using vSphere we've never had an issue with vMotion causing any data issues, at my current workplace our DRS threshold is set quite conservatively and we've recently had a MySQL Consultant tell us we should not vMotion our Databases at all. But obviously we do vMotion the database hosts whenever we patch our esxi hosts or perform maintenance and have never had any issues before. I said that was bullshit, at my last place we had plenty of them with DRS in Full-Auto aggressively migrating databases & other workloads around without any issues. Recently we did a test, we simply vmotioned our database slave to every host in our cluster, while this was happening we got relay-log corruption and slaving has stopped. I'm scratching my head trying to figure out what happened, at the same time we were doing this it moved another DB Slave around to maintain affinity rules, the other VM didn't have any issues at all. I Find it hard to believe that vMotion would be a risky thing, it's one of the selling points of the software and it's something we've done plenty of before but is only suddenly now causing issues?

Still scratching my head too, there was no failover actions taken, the migration completed and the VM did not pause during the migration. Looking at the binlog, there is 2.5MB of zero bytes starting at the query it has failed on, the binlogs continue after that as normal (the slave was lagging by a few hours when this happened, the IO thread is ahead of the SQL Thread) FSCK reports no errors on the filesystem either. It's like a file buffer was zero'ed somehow during the process of migration, I would expect the vmotion process to do some kind of checksum but maybe not?

Just checked, we are running an old version where this is the default, confirmed with a "show global variables" It might be worthwhile for us to modify this, I notice that on 5.7.7 and up the new default is 1 Still weird though, the vmotion shouldn't impact the guest to my knowledge but I guess there's a difference between theory and practice.

I think what they focus on when they think Docker though is the API etc rather than the actual virtualization aspect There are some benefits in that it simplifies deployment & scaling of your application, and allows you to push the container through a pipeline i.e dev > test > prod knowing that it should work the same way in all of the stages. If you have a microservices architecture or running web services that you want to be able to easily scale horizontally it can be quite useful I think. But I believe that the biggest problems we found were that the security isn't good enough for what we do, the networking aspect is garbage & our applications aren't really conducive to horizontal scaling yet. This is why I'm kinda excited about vSphere Integrated containers, everything runs as it's own VM and the networking is the same as any other VM rather than a bridge, which means we could use NSX to control access between each container. theperminator fucked around with this message at 22:37 on Nov 21, 2016 |

I have a couple that are wildly incorrect beginning the second they migrated to a 6.5 host. From my understanding the vmware memory graphs won't generally match what the OS reports because the hypervisor is unaware of freed memory by the guest. We've found for instance that our Java Applications only use 2GB out of the available 8, but after running for long enough with enough Garbage Collection happening, all of the memory gets touched and the memory usage of the guest is reported as 100% by vmware What does the "Active" metric look like for your VMs?

A man can dream VIC might fit the bill, runs docker containers each inside their own photon instance on ESXI, though you still need to create/start the containers via the docker API https://vmware.github.io/vic/

It's basically a way to have a hybrid cloud solution without having to screw around too much. Your on-premise and cloud compute will be manageable from the same interface with the same tools & workflows, you can live migrate vms to/from the cloud, you can easily set things up so that you can fail over to the cloud. NSX allows a lot of cool things like sharing the layer 2 domain across sites easily which means a VM failover to the cloud won't require IP reconfiguration, network ACLs that apply depending on the application traffic detected, or tags you've assigned to the VM rather than static policies you have to update. AWS products seem really geared towards web applications that you scale horizontally and load balance automatically etc, but there's a whole lot of business that doesn't work that way. Plenty of financial orgs with lovely monolithic java apps etc There's probably a lot more but from the POV where I work the above is what's interesting to us.

evol262 posted:I mean, this is basically what every other hybrid cloud solution does (minus the migration from the cloud). I'm not seeing the value except "it's still VMware". But I'm not convinced that's a benefit when you're paying twice Because if you have a multi-cloud setup across AWS/Azure/On-Prem you can easily integrate them all and migrate workloads around, deploy workloads with the same tooling. quote:AFAIK, AWS Direct Connect already does a lot of this. Not all. And it's not that NSX isn't an interesting technology, it's that I legitimately don't understand why orgs looking at this wouldn't just also learn AWS tooling When you do micro segmentation and microservices at scale you spend an awful amount of time making firewall changes, networking changes to account for new services every week. Being able to deploy a new application and have the deployment process configure all of the networking/firewalling across different cloud providers/premises automatically is awesome. quote:Well, that's the cloud in general. You can spin up monster instances which will run lovely monolithic Java apps or c++ abominations which have been ported in the most half-assed way across 3 different UNIX variants then Linux (I also came out of finance) You can also hot-plug RAM & CPU so you can vertically scale without having to shut down your instance You can migrate the workload instead of blowing it away & starting again when amazon decide to retire the host your VM is running on. quote:Horizontal scaling is mostly there for relatively stateless applications or sites which simply can't be vertically scaled in any kind of efficient way once you make the front-page of Reddit (for example) Still, horizontal scaling only works if your workload supports it. some of us are unlucky enough to deal with horrible messes that don't scale like that. As a matter of preference I generally would prefer console access because if something breaks I want to know why. but there's not much business sense in that unless it's something that keeps happening.

BangersInMyKnickers posted:My guess is at some point something breaks and any page that has ever been written to gets marked as permanently active and it persists until the VM restarts, then promptly comes back. Having that bar represent consumed memory would be absolutely idiotic considering the opportunistic caching the OS and application code is almost certainly doing. Guest memory management is irrelevant to the hypervisor, once a page has been touched by the guest the hypervisor considers it used by the guest until the VM is power cycled or ballooning kicks in because it has no idea what blocks have been freed by the guest. this is why if you look at the cluster overview you'll notice that memory usage doesn't go down. I've had a lot of issues with this on account of memory overprovisioning combined with busy java apps in the guest that do a lot of garbage collection and then subsequently use up every single byte of memory assigned to them over time, while the memory usage from Linux' point of view was never over 50% Still, Active shouldn't ever be that high and it's clearly a bug. theperminator fucked around with this message at 00:07 on Mar 25, 2017 |
