evil_bunnY posted:Heh. Have you looked at the prices of decent 10GBE switches? I mean 10GBE is a good idea anyway, but it's not exactly commodity-priced yet. You know, this is the only time I've been really happy with my Dell 65** switches. I spent about 1/5th the cost of a dedicated 10G/e switch for a couple of plug in boards and transceivers, created a new vlan and voila I have a 10G/e iSCSI network.

BelDin posted:Good luck with that. VMware is like InfoSec. It's the IT generalist's specialization. It definitely to be jack of all trades, master of many in this area. My experience may be different, but I'm expected to perform minor miracles every day, know more than the admins about their own server functions, and more about networking than anyone else where I work. Yep. To be a good Vmware administrator you need to.. 1. Know how the physical servers work. 2. Know how the OS's use resource. 3. Know how networks work (specifically vlanning and mtu if you are dealing with legacy networks). 4. Know how storage works. 5. Everything else I forgot to list. On the upside: Knowing VMWare is a hot thing right now and I'm on my third implementation (Started with ESX 3 in a webhosting environ, moved on to 4.1 in government, and now I'm doing a 5.0 deployment back in the corporate world). The first one I was just a line admin implementing someone elses plans. The second time was me helping design but not doing any of the implementation. The third one I've done it all myself from the ground up and so far it's the best one yet. Though I want to know how to get my hierarchical view back for my VM cluster so I can see what is where at a glance. Anyone know how? For a visual of what I'm talking about. I dropped everything into a cluster and this was the result: Is there any way to go back to  host -Virtual machine host 2 -Virtual machine Rhymenoserous fucked around with this message at 17:46 on Mar 7, 2012 |

Yeah that's just a pain in the rear end, I wish it would show the hierarchical view ala a non clustered vcenter implementation. It tells you a lot more at a glance.

So I'm virtualizing an old MSSQL box, a 2005 era IBM X Series 3850 M2 with 64G of memory. Someone correct me if I'm wrong, but I should actually give it less resource than the old physical machine correct? *new servers are DL380G7's

Moey posted:Anyone ever come across a folder on a datastore that will not delete? Folder is empty. There is nothing else on that datastore, the drat folder just wont delete. I am going to blow it out anyway (and that whole storage device actually) but wanted to make sure there is nothing that I am missing that is somehow relying on this empty folder. One of your hosts is causing the problem, it thinks it has something in the folder, I've had this happen in the past and the only thing to clear it up was a host reboot. That was in ESX 4.1, I haven't run into this in 5.

SpaceRangerJoe posted:Job related question. I've worked with Hyper-V for a while now. Nothing fancy, but some single and multi host implementations, as well as setting up a cluster once. I've only worked in MS shops. I am interested in expanding my knowledge about VMs. Am I wasting my time if I continue working with Hyper V, or should I just try to learn VM ware? I did get a Hyper-V implementation book the other day, but a $35 investment hardly locks me into a certain path. I just want to end up with a useful skill set in the end. Generally VMWare is a generation or two ahead of Hyper-V. I like hyper-v for labs, I like VMWare for production.

This way I can show how cool I am with a printed savings estimate after "Wrangling with the vendor".

Kerpal posted:Has anyone ever tried actually backing up ESXi? I'm a little late upgrading from ESXi 4.1 to 5.0 U1. VMWare's upgrade guide warns that you cannot rollback to a previous version once upgrading. Googling around people seem to suggest that there is no point to backing up ESXi. I know you can use the vSphere CLI script vicfg-cfgbackup.pl to backup the configuration. Would it then be possible to rollback by reinstalling ESXi 4.1 over 5.0 and using the saved configuration file? Our environment is very simple, a single host with 10 VMs, no vCenter, update manager, or plugins. It takes like 20 minutes to install ESXi and you have the configs you can just import them. Any bare metal restore you do would take longer than just reinstalling and applying the config. So uh yes, if you want to roll back just install etc. Allthough you'd probably be better off just doing a fresh install of 5 and re-attaching your VM's from a time wasted standpoint.

Yeah, were I him I'd just schedule a 4 hour downtime window at some point and just do it. 4 hours is more than enough time to dig through all the permutations of "Well the upgrade didn't work, I'm going to isntall 5, the 5 install didn't work, I'm going to install 4.1." etc. Honestly I don't forsee any problems unless you are trying to install it on a graphing calculator or something.

Kerpal posted:It's all on a local RAID. We have ESXi installed on RAID 1 with VM data stored on a RAID 5. Are you saying I can install ESXi 5.0 on a USB flash drive, boot off that with the host, and then add VMs residing on the local RAID to its inventory? That would be a great way to test it. Most people I know running ESX on a local raid are buying machines with SD card slots now so they can run the hyper visor off one of those.

sanchez posted:In place upgrades of esxi 4.0 to 5 on hosts with local storage (gently caress local storage), has anyone experienced any kind of disaster? Coworkers have done a few but I'm nervous all the same since the client has no vm level backups and rebuilding all of their servers in a weekend would suck if the datastore gets eaten. I'd be using the iso. Backup the virtual machines to some separate storage before doing the upgrade if you are that nervous (USB Drive maybe?) I honestly wouldn't even do it if they had no off host backups and you couldn't facilitate a cheapo solution like a USB drive. Edit: Is there a vcenter server involved? If so vmotion the VM's to another host then do the upgrade.
