We'll most likely be getting a Compellent SAN with an SSD tier, so that's taken care of (I assume that's what you mean by SSD caching?).

I did some messing around with pricing, and I don't think the value is there for Fiber Channel. An 8 Gb FC card is $700, a dual port 10Gb is $600. Add in the cost of FC switches and it starts to not look very great. Though FCoE could be useful, assuming it uses the same physical connections on the SAN as regular 10Gb.

I also think that politically, anything FC would be a tough sell to the rest of staff. We just recently started using iSCSI for some storage, we've got a simple array that's a couple years old, and that's pretty much it. Even then we're basically using it as direct attached SCSI. So change is tough.

We're working on that overall, but it's nice in a case like this I think to point out a few areas that won't change (or at least we're not buying hardware that forces a change). If everything is loaded up with 10Gb it's a lot easier to switch to FCoE when we've fudged it saying we'll start with iSCSI.

It looks like the Intel X520 and X540 (the cards I'd be using) support FCoE, though not sure about switching FCoE. Guess I need to dig into that awful EMC storage book again.

E: Looks like the 8024 does... something with FCoE:

E2: I guess so, this sounds useful, right?


Our network admin is still scared of link aggregation, so no chance of any help in that department. Just another thing I gotta figure out myself.
Yeah it isn't something you buy lots of, you would by maybe 1-2 8 port switches, and hook them to 4ish hosts(assuming you want a full mesh) The real gain in using FC is the lack of latency, 10GbE w/ FCoE would be a good choice if you don't want to spend the cash on full blown FC, the main thing you are trying to eliminate is the TCP encapsulation and the wait for a reply before sending the next packet, drastically cutting latency.
more here http://www.unifiedcomputingblog.com/?p=108

As far as your net admin goes re assure him that you can have a stand-by/failover nic for port aggregation

Of course I don't know how many servers you have or want to consolidate so only take what I say as something to consider.

These are not in Dell's Force10 line (http://www.dell.com/us/enterprise/p/force10-networking) so I have to assume they are rebranded from some other company.

I could be wrong, but based on Dell's history and the design it looks to be a rebranded Brocade/Foundry.

As far as I know everything in the powerconnect line is rebranded brocade.

EDIT: I'm using Dell 6248's with the SFP module plugins in the back for my 10G network and it runs like a champ.

So I'm starting to juggle data around so I can upgrade my datastores to VMFS5. Is there any reason I wouldn't want to combine, for instance, two 2TB LUNs/VMFSs/datastores that are on one RAID set into one 4TB LUN/VMFS/datastore?

edit: I'm storage vMotioning VMs off of datastores, deleting the datastores, and creating new ones, not necessarily because it's required, but I have the room so why not.

That really depends on the activity asked of it right? But let's assume the virtual machines you're thinking of combining into a single datastore don't do a whole lot of datastore transfers - VMware will tell you that you should plan a limit of around 20-25 virtual machines in a lun.


Just on a side note, because I'm so frickin happy with our new purchase, let me gush about it for a moment.

I can say that Hitachi's SAN kicks rear end. We just purchased an AMS2100 with x6 8GB FC ports, and unlike what I've had to do with our NetApp filer, you do not have to assign pathing! With Hitachi, you create your host group and associate the FC ports with the WWNs of the servers, and you're done - nothing more to it. Internally of the SAN, pathing is auto-balanced across the hosts, so finally there's a GOOD reason to use Round Robin balancing.

Never really expected to see anyone praise an AMS. We ditched an AMS2300 for Compellent and the UI was unresponsive and horrible, and IO performance was really terrible. Have they improved SMN2? It was taking me ~60 seconds from click on each link to page load.

If your storage does not have VAAI hardware locking you want to be careful about the number of VMs on each datastore. If you do have VAAI it is not a big deal.

Ok so this is a problem I'm having with getting my xendesktop install to work with my netscaler outside of our work environment. I was trying to use a self signed certificate but I kept getting authentication issues. So I went through the event log on the XenDesktop server and I found error 18001 with the following details:


After googling around I found that it’s cause by using a self signed certificate. So that made me go out to godaddy and purchase one for citrix.mydomain.org


Once it was issued it gave me a file download and inside were the following files:


I installed those on the server but I also need to install it on the netscaler. I already had the following self signed certificates on there:


I went out and clicked install from the SSL -> Certificates screen and filled out the form like this


I get the following message twice when I click install


Then I get this error message:


Any ideas on what I need to do? Do I need to download the certificates in a different format for the netscaler and try to install?

The netscaler is the Internet facing and acting as a CAG, right? If so then that is what you need to put the SSL cert on.

Me and the guy above your post are trying to say the same thing. If you did the request for the server you need to do the process again for the netscaler. If the netscaler is acts the same as a CAG you do not need an SSL cert on the XenDesktop server. You need it on the Netscaler.

I don't know what SMN1 was like, but SMN2 is essentially just a web server you install on a guest vm, and it gathers the info from the filer. Totally refreshing of all data can take ~10 seconds, but normal clicking and working is very snappy.

Even with VAAI "locking" (don't remember hearing this term before), all storage vendors and VMware have always said 20-25 vms per lun, and I'm wanting to say Scott Lowe states it as well in Mastering vSphere 5.

Hehe, whenever I say "Scott Lowe" I imagine those kids in the desert in beyond thunderdome talking about the Capt.

All storage vendors and VMware have always said "It depends," and when pressed for a number have said something low and safe. With VAAI and some help from array-side caching technologies, you can get absurdly high densities under the right conditions. EMC has claimed up to 512 VMs per LUN, NetApp was claiming up to 128 on vSphere 4.1--I'm sure that's higher by now.

You're right... In terms of a what a typical buildout would be, it's safe to say that it would be the 20-25 per LUN mark, but with higher end builds you can do a lot.

Looks like Cisco doesn't even have an equivalent, so I'm guessing nobody does yet. And we can get it for only $10k!

Except some chassis-based blade/FC stuff Powerconect switches have nothing to do with Brocade.

All Powerconnects are built on Marvell or Broadcom platforms, exclusive designs for Dell.
It's actually not hard to tell as they don't even look similar to any Brocade switch. :P

They work very well for me, a year ago I bought 3 for like ~$15k if I remember correctly... :) A pair of 8024F is working fine since for mixed iSCSI/LAN in my server room (storage-server-cluster backend, diff subnets instead of VLAN) plus I have an 8024 for 10Gb workstation aggregation, all are connected to my core E8212zl. The 8024 (non-F) was a true gem a year ago, nobody offered stackable 24-port 10GBASE-T (+4 SFP+ combo port) switch especially not for $5k... :D

Keep in mind that this depends a lot on how you use your storage, as well -- VMs per LUN is tied far more to VMFS metadata operations (which are locking) than VM disk I/O (which does not create any locks). If you're not a big user of thin provisioning, for example, you can get away with way higher densities as well because your only metadata operations occur during VM create/delete/poweron/poweroff and when you swap at the hypervisor level.

Edit: Snapshots, too, especially if you have a tendency to keep them around for awhile, because the delta files grow dynamically.

This is probably the laziest thing I'll ever post but does anyone have a decent "business case" they've used that successfully laid out the pricing for machines, storage, cabling, 10G infrastructure, the full works.

I want to put together a proper plan with costs to try and shame management into doing the right thing in our three datacenters. I'm aiming for about 100 vm's per DC (50/50 between 2 and 4G of ram) , 10TB of storage, all aimed at being able to build up a fully comprehensive testing tier (that we completely lack).

What I don't want to do is open word and reinvent the wheel as I'm trying to squeeze this in between 50 other emergencies.

Pricing is typically considered to be vendor-confidential privileged information, and it's rather damaging for vendor relations to share it. If you have a budget figure, call them up, and see if they have anything that fits your range.
