Yeah pretty much agree with Three, most of the UCS stuff is things you can already, or free, do if you know how to utilize your feature set given.

Yeah the Gen3's are reasonably priced, smartnet renewals can be a pain sometimes, with promotions that never seem to end, I do like if you are just unhappy with the server TAC will basically send you a full new one.

I do wish they would use some AMD procs in their UCS line up however

The hardware detaching is cool, but how often does anyone need to use it? It'd be easier to just use auto deploy for ESXi hosts, and only bad people run physical workloads nowadays. (Plus who boots Windows from SAN? Although, technically you could just swap the drives.)


I use it pretty frequently. I also like the idea of policy based management and being able to manage 200 blades from a single interface without having to buy a manager of managers.

It's also pretty rad when you can sort your blades into different organizations and then apply permissions/policies. So if you have 100 blades you can give say 20 to dev, 30 to QA and the rest to production. Then the Dev/QA engineers could have total control over their blades without being able to mess around with production stuff.

Taking that one step further it opens up the option for production or QA or Dev to borrow resources back and forth without having to deal with re-installation/deployment if you don't want to.

It's also nice to pop in a new chassis then go click on your service profile template and tell it you want 8 more ESX servers configured in exactly the way you need. As an example our ESXi servers tend to have 6 NICs configured (lab machines with a pair of NICs on a standard switch, a pair on a dvSwitch and a pair on the Nexus 1000v) and our hyper-v systems only have 4.

I find UCSM is a lot friendlier when you have multiple administrators poking around doing stuff. If two people try to open a KVM console for the same blade it'll offer a chance to share it. Last time I dealt with Dell, HP and IBM they usually just said "sorry this is locked! try again later!" which was really frustrating when I was the one using it but my browser crashed from trying to use virtual media. This may have improved in recent versions. I haven't had a chance to touch that Dell M1000 in the lab.

quote:

It would be better to use NIOC.

I'd prefer real QoS to NIOC. Mostly by virtue of QoS being honored outside of the dvSwitch.

One obvious reason: vMotion can only happen between processors of the same manufacturer, so if someone's running an AMD shop already, you can't run a (robust) mixed cluster with UCS in the middle.

Whats your deployment scenario? Hyper-v isn't always 'way cheaper'. I mean it can be but it depends. And yes you can run your scvmm instance as a VM.

For a small setup thats supposted to have AD, Exchange, SQL and a few hosted desktop (terminal services or whatever its called now) for about 10-20 users each. Hyper-v seems to be the easiest way to get going, since it's included with the Microsoft licenses I'll need anyway.

Is this easy to visualize or should I make up a drawing to better explain?

Does anyone here have any background scripting esxcli commands on 4.1 hosts?

We are doing a massive storage migration and each LUN I remove from the host has to me masked (see below) :

esxcli corestorage claimrule add --rule 110 –t location –A vmhba3 –L 156 –P MASK_PATH
esxcli corestorage claimrule add --rule 111 –t location –A vmhba4 –L 156 –P MASK_PATH

I have to repeat this for each LUN being removed. Is there an easy way to script this process?

Edit : BTW, 5.0 makes this process much easier and is all done via the GUI with a simple right click. 4.x is a miserable beast, especially when you have to migrate about 100 LUNs. Shoot me now.

Edit 2: We were able to script it (bash script) easily, I would love to see if we can do this from power cli.

Handy script I wrote earlier:

code:

for h in <hosts here>; 
do
ssh root@$h 'for i in `ls /vmfs/devices/disks/ | grep naa.600` ; do esxcli storage nmp device set --device $i --psp VMW_PSP_RR; done'
ssh root@$h 'for i in `ls /vmfs/devices/disks/ | grep naa.600` ; do esxcli storage nmp psp roundrobin deviceconfig set -d $i --iops 1 --type iops;done'
done
Goes through each LUN and sets the native multipathing to use round robin then adjusts each lun to shoot one iops down a path before switching to the other one. With this setup we got a nice increase in performance over the default of 1000 iops before switching paths.

When it comes to virtualizing things like exchange that use all the ram you give them, how do I know if I should allocate more memory to the VM?

Right now our new server is floating at 8.3-8.4 GB used out of the 10 we gave it. Everything seems to be running fine. It's a small server with 75 users and 25 GB of mailboxes. I'd like to say that we are fine since we're not at 100% memory on the VM. I'm just not sure how to tell definitively.

This may depend on the application honestly, there may be different sets of perfmon counters, etc. to check to determine if you're experiencing memory pressure or not.

That's when you start looking at the application performance counters and see if they indicate RAM pressure. Specifically, the Memory Paging Counters are a good place to start.

This will tell you gently caress-all when you're running in a virtualized environment with a balloon driver, though. By increasing your RAM you might actually be increasing how much you swap.

Exchange likes to cache, depending on what you are making it do it can take a lot. If you are on standard or higher you can always hot add ram, so you can start low and gradually add more if ram is being the bottleneck.. Generally I'll run VM's at 65-80% usage or vRam.

The good news is we're not even CLOSE to our full RAM utilization. Even if every server that was allocated memory took 100% it was allocated, we'd be barely over 60% total utilization on that VM host. We're sitting at 17 GB total allocated out of 32 GB on that blade. I can afford to allocate more, but I only want to do it if I have to. Right now I can fit several VMs from our other host on this, if the other host goes down spontaneously. We're not at risk of swapping at all.

I'm just at a loss when Exchange will take literally every byte of RAM it can just to cache, but I don't have a clue how to tell if the RAM is bottlenecking us. That's where I start getting out of my league.

Swapping being reported from ESXi is the LAST thing you want to see, Ballooning and Compression should be warning signs that your host is running into oversubscribed ram issues. Transparent page sharing, is a great function which helps lower ram usage on the host as well.

Ram would be the bottleneck if you are seeing the guest page it's memory into swap, usage runs ~90% during normal operation, the windows OS complains about memory via event logs or warnings, and/or performance is poo poo when you can verify IOPS, CPU, and network are not constrained.

Exchange does start spewing log errors if it gets really low on RAM, I've only seen it on single server 2010 environments with 4gb of ram though (not my idea). Once you get up past 8-10gb it hums nicely, I suspect (un-scientifically) based on your environment size it'll be just fine with 10.

It's honestly pretty straight forward so long as you don't select simple install. Also put SSO in multi-site even if you are currently one site, there is no easy way to change it after you finish it out.

Replacing certs in 5.1 was a bit more tedious, but that tool looks pretty cool.

Yeah, as long as you don't choose the wizard (which should be the safest).
And as long as you choose multi-site (without being warned that you can't change later).
And as long as you don't change your RAM/CPU count after installing (or you'll break the Java thumbprint).
And as long as your password doesn't have a ! or \ or other character in it (since it passes the password via the command line).

The 5.1 upgrade process sucks hard unless you've been through it and figured out all the "gotchas". Enterprise-grade software should not be this difficult to install/upgrade. VMware messed up. Your software shouldn't have "traps" set up that people can fall into.

Hello beautiful.
This...is gonna get gross.

So I am taking the 5.1 ICM class remotely starting next week. Later in July I may be able to get my company to cover the optimize and scale course for VCAP.

I am wondering if there is any major benefit to the higher level cert other than sending your résumé up a notch? Essentially I'm trying to figure out which path to go for -- focus on VCAP or go for the VCP-DT? I am leaning towards the latter for diversity but I was wondering what others thought.

Currently I am one of the senior admins at a MSP and we are very VMware focused. We have View in production but few people use it.

I have the VCP/VCP-DT, the VCP-DT the outline for the DT was great the exam felt like "NAME AD POLICIES TO OPTIMIZE PCoIP", when this new job starts I am going to pass my VCAP-DCA as I get a nice bonus! There is also a VCAP-DT, which looks fun, and my site should be covering all the objectives. Video editing on the laptop I have is much slower than I thought. The VCAP is a great course to go over, Troubleshoot especially.
