    I'd upgrade to 5 1st and then go to 6.

    e) Scratch list
    Hmm..I've never seen that one before..

    It's really only picked up in the last 2 days.

    As for the Cross vCenter vMotion. It's new in vSphere 6.0, You can find the answer in the What's New overview PDF. http://www.vmware.com/files/pdf/vsph...6-0-PLTFRM.pdf

    OT but funny you mention Dell EQLs. We were one of the first ones in the UK to trials these ones back in the day (4k series or something) and the engineer / sales monkey combo were trying to tell us how great and stable and whatnot it is.

    Whilst they were still chatting to our director i managed to blow it to bits (software wise) .. Needless to say the Dell guys where somewhat confused how that was possible and were embarrassed ..

    We were still OEM partners at the end and I loved 'em .... Even though the initial setup was a bit rubbish network wise. You had to play with VLANs to get it setup in the right networks ... Ah ... good old days ..

    I still think of Equallogic as one of the best SANs, especially for the smaller environments. Easy to setup, easy to manage and up to a few units easy to scale. Had one until very recently and I was more than happy with it. Did it's job for more than 3 years without even a single moment of downtime or issues, effectively 100% uptime.

    Ahhh... I was like "did I miss something in my 6 months of study and past 6 months of VMware experience! ...are you going blind Trevor!"

    Ya I'm liking them so far but not sure if I like the fact the you can only have one massive LUN for the EQL's. Subdividing datastores inside SAN HQ and that's what is dished to vCenter. Hopefully it will last a few years before we exceed the IOPS of it. We got a EQL 4100s; 22 drive @ 900GB's @ 15k.

    That was my track records at President Container, had a workhorse EQL 4100s carrying 12 servers for 3 years on a boot-from-SAN config with all the servers being diskless (jibbajabba) I think they sold my predecessor on the wonders of EQL's to him like you and that's why they did diskless...it was SO NOT GOOD THOUGH! ... it was done for all physical boxes, they took 15+ minutes to boot on diskless Dell R610's. ....I'm so happy VMware reboots are 2 minutes tops at my current job, I hated waiting for 45 minutes for servers to post while controlling political bullshit phone calls every 3 minutes about why servers were offline!!!!!!

    Even though the design was horrid, that 4100s trucked through it and NEVER failed, yes maybe a drive did here and there but it was a RAID 10 no worries one drive, pfff....Hence why we got the cheapest EQL we could afford to build out the cluster.

    I actually just finally got all my hardware at my job this week for the ESXi 5.5 cluster.

    The twin N3024's arrived Tuesday (configured them in 40 minutes) racked and stacked them Tuesday for the iSCSI/vMotion fabric. The (5) N3048's (228 Gbps throughput) arrived Friday, configured them, racked and stacked them and then moved over all the connections at 5:01pm yesterday (I was like GTFO of the office I'm pulling cables go home it's Friday!!!!) from the Dell 2824's (don't ask my previous predecessor didn't know they were campus-grade layer 2 switches NOT CORE SWITCHES!!!!! - 48Gbps throughput /facepalm SMH!!!)

    VMware licensing arrived yesterday too so I got out of Free mode and I can live in vCenter again (LOVE!) - Next week is P2V Migrations, but now with a 228 Gbps backplane they 'should' be quick (The ESXi 5.5 server's both have 4 bonded gigabit connections for Production so 8 GBits aggregated - I know I tried to get 10 Gbit, but wasn't happening - someday). Each server has 12 gigabit nic's. Will be nice to migrated them off local arrays. iSCSI has two connections, 1 active/1 standby. - Mgiht make it two active and play with fire and say **** it for FT but I may want FT. Our IOPS are very low so it will be interesting as time moves along. Why Dell shipped the SAN with only 2 nic's per controller I'll never know must have miss that in the quote /failboat!

    In a few weeks after the P2V's are done moving the network over to a 6 vlan setup: 1 /23 (really will be 2 /24's but the first block will be static and the last block of /24 will be for dynamic) and 5 /26's for departmental security concerns. It will be a complex IT infrastructure in a few months, lol! ... perfect work-lab for my certifications.

    But back to the OT, keep them coming. Just had a small nerd rage rant

    Almost.

    Other (Vendor-Specific) - Which when they say "Vendor" they are still meaning VMware. Check out the vBrownBBag VVols series.

    Ok; let me take a crack at this; probably will be easy peezy for you guys.

    Q: You try to access the ESXi DCUI via Putty at 172.16.80.13 (or similar tool) but when you go to access the server you get a "failure to connect" warning and your like...

    After you do some digging you look over your Servers, Cisco switches, and Sonicwall your curious what it could be. On The Cisco switch you find this:

    !
    !
    !
    Extended IP access list RedSox_suck!
    09 remark you'll never guess it
    10 deny tcp any host 172.16.80.13 0.0.0.0 eq 22
    20 deny tcp any host 172.16.80.13 0.0.0.0 eg 23
    30 permit ip any any
    !
    !
    !


    What's happened?

    I don't have any of that gear, no touched a Sonicwall, but given port 22 has "Deny" against it, any TCP traffic to the host will be blocked using that port.

    Hang on, where do you get the message ? You say DCUI via SSH, so you connect to the server via SSH and run 'dcui' and you get the error then or the error when you SSH in the first place ?

    Either way, both DCUI and SSH need to be enabled if you want to use SSH to connect to the DCUI ..

    Correct. SSH is port 22. So even though SSH is enabled on the ESXI host the connection wouldn't be established.

    Q: You just made a brand-new VM and you selected Windows 7 64 bit and you install Windows, you do all of the normal stuff once Windows is done installing: settings in system for best-performance, turn off the Windows firewall, run msconfig for startup programs and you do Windows updates and let it do it's thing and walk away. You step away from the vCenter Console for 30 minutes and come back and the VM is suspended; Why?

    Even in VMs, Powersaving will suspend the OS after X-Minutes / Hours.

    the reason cloud be which is described by @jibbajabba....or because of using a thin vmdk under the VM, and the LUN went out of space (growing disks), so (all of) the VM(s) was/were suspended which is/are on the LUN.

    Correct, with default settings Windows 7 is set to balanced in power settings and hard drives are set to turn off after 20 minutes of no input. This is why after 30 minutes the VM was suspended.

    So guys, no pressure. I told a number of people at the local VMUG in NY/NJ about this forum and many of them know of this thread specifically. So Koodos to that and no pressure on keeping it alive.

    That message I just formulated in my brain however theory is sounds I think.

    If you opened up say a Putty and tried to use a SSH on a server that you knew had SSH turned on, that error would occur if the port for SSH was blocked on the physical layer by a ACL.

    Tried to make a error that even though on the VMware side things looked fine on the physical layer someone in your networking team made a boo boo. Never know might come in handy sometime in the future.

    Question.

    you set up you virtual switch in esxi5.5 and create 3 portgroups on it, each tagged to a separate vlan (5,10,15)

    you hosts uplink nics are connected to a cisco switch which has trunks enabled, and permits all vlans.

    guests in port-groups 1 and 3 (vlan 5 and 15) can connect but not devices in port-group 2(vlan 10), although all NIC on the host are showing up and there are no errors on the switch port.

    What could be the issue?

    VLAN is not on the switch. VLANs are automatically added to the switch when a port is configured as access port, but won't if they are just added to the trunk allow list.
    Code:
    switch#sh vlan
    Created by: D-Default, S-Static, G-GVRP, R-Radius Assigned VLAN, V-Voice VLAN
