How loud is your D-Link switch? Does it generate a lot of heat? Do you have it in a room in your house? General thoughts about the switch? That one is slightly cheaper than the Netgear one I was looking at.. Thanks

Yes I agree its scope creep for sure! Sorry about that.. Various reasons for my questions: 10 Gig switches are expensive, I am funding this personally 10 Gig switches are loud and rackmount, this causes me logistical issues at home (condo) 10 Gig switches are hot, this causes me more issues at home Any additional HW adds that take up space directly increases the probability of a divorce in my near future Need 10G for all flash VSAN Need 3 hosts for VSAN Would also like 10G to the rest of the network Should have probably outlined this to begin with... Any help or insight would be appreciated. Thanks!
..and then to connect the cluster to the outside world, would I need another port on EACH ESXi host? Have you actually tried something like this before or is it just theory? Thanks
OK but what about if I need 3 hosts? How would I wire/configure this considering that if one host goes down the other two still need to talk to each other?

Hi, This may be a stupid question but I can't quite figure out the answer so I might as well ask. I have two physical ESXi hosts in my lab and for various reasons would like to eliminate the physical switch between them but still retain full vSphere functionality (vMotion, HA, DRS etc). Is there a virtual switch/repeater product that I can buy/use (deployed on both ESXi hosts in a HA configuration) that can give me this functionality? I would then use pNIC ports on each ESXi host to talk to each other and additional pNICs as switchports to the outside world. i.e. could I do this with some sort of multi-Vyatta configuration? NSX? Need multi-cast support also. Thanks for your help!

Hi, So my goal is to have weekly backups go to one VDP appliance, and monthly backups go to another VDP appliance, on a separate datastore. I am stuck on VDP v5.1.1 for now since I can't upgrade my vCenters yet. What I am trying to do is protect my backups from a datastore failure and/or VDP OS corruption - both of which have already happened in the past. My question is, will I be able to just deploy a 2nd VDP appliance and tell it to back up the same VMs that are already being backed up by the 1st VDP appliance? I'm wondering what the complications would be, i.e. if the 2nd VDP only runs a monthly backup, will it be smart enough to get all the changes from the previous monthly backup or will it pick up the CBT files from the last daily backup from the 1st VDP appliance? Thanks!

Just want to give an update in case it helps: - issue was application users from the old vcenter were still registered in web client - web client > administration > sso users and groups > application users - problem was i couldn't tell which user belonged to the dead vcenter as they do not have references to hostnames or IP, did not want to risk deleting the wrong ones - end up restoring the dead vcenter from backups, then did a full uninstall of vcenter, which deleted the proper application user accounts from web client all is good now

Hi, a vCenter died in our environment, and now whenever I log into the vSphere Web Client, it gives me an error message at the top saying it could not connect to one or mover vCenter Server systems. In Administration > SSO Users and Groups, I see a whole bunch of Application Users that I'm probably supposed to delete, however there is no reference to vCenter name and we have many vCenters so I don't want to mistakenly delete the wrong one. What is the proper way to clean out your SSO registrations (inventory service, etc) when a vCenter was not cleanly removed? Thanks.

THANK YOU for the glorious "why didn't I think of that" moment. vMotioning my VMs now and will rebuild with RAID 50. Have looked at FastPath however wasn't quite sold on it. Do you have firsthand experience of it in an ESXi environment with typical server workloads? Is it a software key or hardware key? I noticed that there are different SKUs for 9260 and 9265, is it transferrable in any way later if I upgrade? Do I need to reconfigure the array after installing FastPath or I just type in the key after I buy it and it just works? Thanks again!
Hi, Not concerned about TRIM, the native garbage collection on the SSDs work well and I am going to live with a periodic secure erase of the array. Thanks

Hi, Thanks for the reply. So in my scenario, I want all the VMs (various workloads) on this particular host to run on SSDs, no need for selective caching. Have run extensive benchmarks and both sequential and random reads/writes are much faster than the platter disks they are replacing. My issue is there seems to be excessive ESXi and VM overhead that is causing a loss of IOPS/bandwidth on the SSD array.. wondering if there are any optimizations I can make to vSphere that can increase storage performance. Thanks

Would like to get some info on whether or not there are ESXi specific tweaks to get better performance out of VMs sitting on an SSD datastore. Lab Setup: LSI 9260-8i RAID card 8 x 500GB Samsung 830 SSDs (TLC, horrible I know), RAID5 (yes I must have parity protection) I have endlessly tweaked the 9260 and RAID settings to arrive at the best possible configuration according to my benchmarks: No read ahead, 128KB stripe size, direct I/O, disk cache enabled, write back with BBU.. I am seeing a pretty big performance hit comparing native RAID performance in windows vs performance in ESXi when I transplant the same RAID card/SSDs into my lab ESXi host and test from inside a VM. Understood there is overhead from the hypervisor, and then overhead from the VM.. but still.. Looking for anyone who has experience with a similar setup and can provide tweaks/suggestions.. Thanks in advance!
hmm yes i am exporting, and my hosts get errors because it seems to be looking for metadata files that are not there. ok i will wait it out, thanks for your help!
5.1. Can you do me a favor, if you are running UMDS, can you look inside your hostupdate\vmw directory and tell me if you see a vmw-ESXi-5.1.0-metadata.zip file? Thanks

Hi, My UMDS is configured as follows: vmware-umds -S --disable-host --disable-va vmware-umds -S -e embeddedEsx-5.0.0 embeddedEsx-5.1.0 vmware-umds -D So I expect to only get host updates for ESXi 5.x. In the umds\hostupdate\vmw directory, I only have these files: __hostupdate20-consolidated-metadata-index__.xml vmw-ESX-4.1.0-notification.zip vmw-ESXi-4.1.0-notification.zip vmw-ESXi-5.0.0-metadata.zip vmw-ESXi-5.0.0-notification.zip vmw-ESXi-5.1.0-notification.zip 4 Questions: 1) Why is it downloading 4.x files? 2) The files are being exported into shared repository. However other UM clients are looking for a file called vmw-ESXi-5.1.0-metadata.zip, which does not exist, which makes the patch update fail in vCenter ("Cannot download patch definitions"). Is this file supposed to exist? 3) Does your vmw directory have this file? 4) When I run vmware-umds -D, I see a bunch of errors where there are timeouts downloading certain files, is this normal? Thanks!!! Any help is appreciated.
