Because no desktop means no sales and one sale could be £100K so we need all 8 VM's running during office hours.
Yes 4 VM's could I guess run all 250 users for a day but if there is a FREE method of ensuring the VM's are there ready to run in their latest state i'll take it
I have heard/seen issues where a VM maxes out at x number of users - so I understand the need for more than say 2 VM's in the farm. So perhaps it's the case that you can't live with fewer than 7 or 8 VMs assuming that the hardware on a single host has enough resources. In that case you can manage fewer VMs by using DRDB, but assuming Windows servers, you'll still need all those licenses for both boxes.
A single VM handles a LOT because it does nothing but direct people to the right VDI VM. One on each host is likely plenty.
I thought he said he wasn't doing VDI, but instead is providing a remote desktop?

VMs for XenDesktop are considered connection brokers. They line up users with virtual desktops. They are like the pimps of the VDI world.

XenDesktop = VDI
XenApp = Terminal Services -

Yeah most blogs I've been working off is each VM should be 4vcpu, 24GB RAM, for 30-40 users, we have 250 so 7-8VM's. To keep server costs down I was going to use two referb servers.
-
@hobbit666 said in Xen Orchestra on Ubuntu 15.10 - Complete installation instructions:
The two server are for Citrix XenDesktop. Each server will have 4 VM's giving 250 users Desktop Sessions (not VDI more RDS). The idea for VSAN/Replication between the two is if one host goes down the remaining host can spin the 4 VM's up so we always have 8 VMs running until the host is fixed.
Is was just going to use XenServer as the Hypervisor as it's FREE and does a lot as @Scott and others keep mentioning
@scottalanmiller He specifically said, not VDI more RDS... but he did mention XenDesktop right before that.

Being refurb doesn't matter as long as each host as enough resources to handle the whole load, then there's the licensing.
So, are you doing Remote Desktop (old name Terminal Services) or VDI?

It's still a terminal server. VDI is a remote desktop too.
Here are the terms:
Technologies: terminal server vs. VDI
Microsoft products: RDS is their terminal server
Citrix Products: XenApp is their terminal server, XenDesktop is their VDI

RD using XenDesktop as it handles traffic better (so we've been told lol) some sites only have 800K connection to us and for 5-6 users. yeah going to look at "beefier" server maybe.
Any people back on topic!!!

really? I've always heard that ICA was way better than RDS for a remote connection protocol. Though I know RDS has gotten better over the years.

This would have been a great opportunity to split this conversation, although I don't really see how it started.

Yes I did know this, but he specifically said no VDI, so there was obvious confusion.

Yup, ICA is the best. RDP is based on ICA but crippled.
RDP and ICA are protocols.
RDS and XenApp are terminal servers. Don't mix RDS and RDP together, they are unrelated.

ICA is the primary reason that people pay for the XenApp suite.

really? Is it still that much better than RDP? I can see the management parts being worth the fees, didn't realize that ICA was still that far ahead to the be primary driver for a purchase.

RDP is a crippled version of ICA. That is what it is. They are not two separate technologies competing. Citrix makes it, removes some capabilities and lets MS license it. So it remains, and will remain, ahead.

Yes, ICA is that much better, worth the price if you are doing hundreds of users, especially those with limited bandwidth at the end point. I've seen ICA work over local, and by local I mean terrible can barely load a webpage or place a call, 3G connections with little to no lag.

DRBD is used as the base for HA in many NAS storage systems.
I think "many" should be "majority" BTW.

@scottalanmiller said in Xen Orchestra on Ubuntu 15.10 - Complete installation instructions:
The difference is that DRBD does not do scale out, you need Starwind for that. But for two node mirrored replication, it's unbeatable. It's the same technology we use for storage clustering on all Linux systems.
Yeah I think we are never going to go over 2 hosts for the Citrix farm. So that will do.
Thx again Scott.Think about separation of your storage and hypervisor nodes. Management can be simplified quite a lot (storage put into "leave and forget" mode).
