Yeah I saw that before, but the VM's need to restart with a host failure.. Can your SAN handle a bootstorm of that many VMs simultaneously without making GBS threads the bed? What I was getting at was with a bigger cluster of smaller specced hosts the impact of a host loss is much smaller, and it's easier to accommodate the failover capacity in the cluster.

What do you guys think is the sweet spot for power of a machine vs price? We bought Dell R710s that have two chips for around $10k each, but I would have felt a lot better buying single chip machines for $5k each. But Intel only has E5 chips in the latest generation that are for dual socket boards, so the best you could do is buy the R610 with two sockets and leave one empty for $7k.

This really depends on a number of factors such as; What is the VM services is the VM supporting the the company? How much resources is the VM taking up? What is the value of the Infrastructure the VM is supporting? What is the VM's estimated ROI? Scaling up hosts vs. Scaling out hosts is a tricky thing sometimes, as scaling out can often occur more than just the cost of a new server, there are a few things you have to take into effect such as; Cost per network uplinks used to connect the server, and if needed additional switching for the new host. Average host maintenance a year(BIOS, firmware, driver, and esxi updates) Power and Cooling costs of the additional host(s). And there are more factors to consider as well.

For those of you who remember me posting questions over the past year about my weird NFS disconnects happening with my Netapp, well it looks like its finally officially a bug: http://virtualstorageguy.com/2013/02/08/heads-up-avoiding-vmware-vsphere-esxi-5-nfs-disconnect-issues/ For me it got solved when I upgraded my 2020 to a 2240 but I wish they would have figured this out sooner. Netapp pointed the finger at VMware, VMware pointed the finger at Netapp. I could have saved a ton of troubleshooting time if they figured this out sooner.

During the process of getting everything up to spec prior to moving to 5.0u1, IBM managed to fry the UEFI on two of our servers because they didn't provide the proper firmware updates. We were so far behind that they should have had us hop to a certain level before attempting to get us to the latest version. The 2nd time this happened, I told them what happened the first time and questioned if we needed to hop to a previous version before attempting yet they assured me it would work. Another time, a hard drive failed on a RAID-5 array at our satellite office that only has one host and no SAN. An apparent firmware bug caused the wrong drive to illuminate its error light and subsequently, I yanked a good drive out of a RAID-5 array when another drive was already down. IBM ended up throwing their hands up in the air and told me to recover from backup. I was able to rebuild the array no thanks to them. Also, when you're paying thousands of dollars for a support contract annually, not being able to be connected to a technician immediately for a production server down incident is loving asinine. My experiences with VMware's support is the polar opposite. I have nothing but good things to say about their support team.

IBM does this -- without hassle or even a question -- but they don't readily disclose the process. Open up a ticket using the online ESC+ tool. As soon as you have your confirmation that the ticket was submitted and you have a case number, call 1-800-IBM-SERV and get somebody, anybody, on the phone. Once you have a warm body, the second they start to ask you for your personal information, ask to speak with the National Duty Manager. You can escalate your case immediately from there. If you want, they'll often stay on the call with you and the technician until they're satisfied you have the resolution you're looking for. Our issue is that one of the engineers in my group is hearing-impaired, which obviously makes this telephone-based route rather difficult. The National Duty Manager I spoke to about this had no idea herself how someone with a hearing impairment is supposed to escalate a case. IBM's support is really rather good from a personnel and policy standpoint, but their processes are dumb. goobernoodles posted:I took over the IT dept at my company a few years ago after my then boss quit and moved onto another company.

I have old phone server software that I installed on a Windows 2000 Server VM using Hyper-V on Windows Server 2008 R2. The software has a hardware key that plugs into a parallel port. We forwarded the port to the VM, however the VM is not recognizing the hardware key. I noticed that one workaround that people are using for USB hardware keys is to plug them into an Network-Attached USB hub. Do you think that I could get away with plugging a USB to parallel adapter into a Network-Attached USB hub or is there an easier way to get the parallel port hardware key working? I do have a parallel card in the server. Also, would running Hyper-V as an administrator make any difference? Does VMWare have better support for parallel ports? I'm not too experienced with virtual machines, so sorry if some my questions are a bit basic. Thank you in advance for any help.

Quite probably a dumb question, but I've finally given up trying to figure out what I've missed. I P2V'd my work laptop using converter and dropped the file onto my home computer. I booted up w/ VMware Workstation just fine into Win7 once. I removed what physical devices I thought I saw and then rebooted. I cannot get back into normal mode but I can get into safe mode. I lock hard while booting into Win7, have to Reset power to get it back. I feel like such a dork, I can't figure out how to troubleshoot windows not booting. I've quite literally have never had this issue and am stumped. I'd like a log file or something to indicate where the heck it's hanging. If this doesn't work, it's just an exercise. I wanted to P2V my laptop so I could run the VPN from within workstation and leave my physical laptop at work. They only assign us one RSA soft token, and it's on the laptop. Would've been nice to run my 'laptop' from within my home PC and work from home over the VPN. I'm not entirely sure the RSA token would work from within a VM, I'm not keen on how RSA soft tokens authenticate to the 'host' it's on; if at all. SecureID is witchcraft for all I know. An Escalation Engineer at my office said he's done the converter process. I's possible he's loving with me just to watch me flounder, but he seemed sincere.

It's been a while, as we stopped using our RSA system, but I think if you can get the original seed file for your token you can install the soft token in multiple places. I recall having the softtoken on my laptop and my phone and either one could be used.

I'm not an expert by any means, but the conversion process should remove any "physical" hardware at the point the conversion is done - or at least anything detrimental to the operation of the machine. If it booted up fine after the initial you probably didn't need to remove anything from device manager. If you were told something different I'd certainly trust your tech more though.

I recall having the softtoken on my laptop and my phone and either one could be used. The distributed token file may optionally contain information to lock it to a single host (I believe this is based on the serial of the HD the token store resides on for Win/OSX tokens, unless you're using some other storage like a USB token). If your org is using this they would have asked you for the DeviceSerialNumber (which you can find in the software token application under Options > Token Storage Devices) when you requested the token.

We do it and other than it occassionally needing to be reconnected, it's been pretty good.

It can be really hit or miss whether the USB2LAN device works with your particular token though. And DR is still annoying to plan for.

I think my plan is to try the USB to Parallel adapter first and if that doesn't work, then I'll consider trying VMWare (currently using Hyper-V) or ordering the USB2LAN hub. The hardware key is for Call Cener Worx v. 2.1, which was released in 2001 and can only run on Windows NT based operating systems and for some reason they stopped purchasing updates after that. I know that the USB keys they released later on were finicky and I'm not sure if the parallel key we have is supposed to be any better.

I don't really have any problem with some of the 4vcpu VM's on my E5649 6c/12t Westmere CPU's, the box isn't incredibly saturated however, it is only running about 12 or so non high load VM's.
