Ric_ Posted September 23, 2008 Posted September 23, 2008 So do we have any? I have a little problem and can't be bothered going into detail unless somebody might have a clue.
ghannahuk Posted November 20, 2008 Posted November 20, 2008 Hi, I work for Precedence Technologies, a Citrix Silver Partner, and we ar elooking to offer a package for XenServer to address the need for zero downtime as a disaster recover solution. I am very interested to hear of your stories and the benefits that XenServer has brough to your school. Have you had a major hardware issue that XenServer made easier to address? Do you have SANs for your virtual images? If not, what do you use? Is your SLT aware of the solution is place and appreciates what it can do? We are working directly with Citrix in positioning the Citrix portfolio to be more applicable to schools and I will be very grateful for your feedback. George
dhicks Posted November 20, 2008 Posted November 20, 2008 we are looking to offer a package for XenServer to address the need for zero downtime as a disaster recover solution. Okay, so what advantages does the paid-for XenServer offer over the open source version? Do you have SANs for your virtual images? No. If not, what do you use? DRBD. See this other thread: http://www.edugeek.net/forums/thin-client-virtual-machines/26716-more-virtualisation-questions-3.html -- David Hicks
ghannahuk Posted November 20, 2008 Posted November 20, 2008 Hi David, Okay, so what advantages does the paid-for XenServer offer over the open source version? For the different editions, click on the following link: Citrix Systems XenServer Editions Basically, the key differences from the Express to the chargeable licenses are: Multiple Server Support VLAN Support XenMotion (live migrations) Unlimited CPUs (handy for support on Quad processors) If not, what do you use? DRBD. See this other thread Many thanks for that, I will certainly go through this. Have you had any episodes where XenServer saved your network from being down for more than an hour? Or, are you using XenServer to save on server hardware (or both)? George
dhicks Posted November 20, 2008 Posted November 20, 2008 Multiple Server Support In what way? We have multiple Xen-based servers on our network. We don't have a decent management solution at the moment (just my own Python script), but Enomalism defiantly looks worth a look. VLAN Support Okay, in what way would I use VLANs with Xen? XenMotion (live migrations) I can already do this with the open source version of Xen that we use. Is the paid-for version better in some way? Unlimited CPUs (handy for support on Quad processors) Curses - is the open source version of Xen limited to just two cores, then? -- David Hicks
armadillo Posted November 21, 2008 Posted November 21, 2008 Hi guys, we just started asking for quotes to replace the servers, switches, PCs with thin clients and some newer desktops. we were quoted £23K to have Citrix on the network which will have 4 HP servers and a blade system with VMWare. The question is why does Citrix cost so much and is it really needed/worth the money on a school network with 4 servers, SAN a blade server? Your replies are appreciated and thank you in advance.
sammy Posted November 21, 2008 Posted November 21, 2008 Hi Ric, we are a Citrix Gold Partner, drop me a message and i will get one of my technical guys to answer it for you.
K.C.Leblanc Posted November 21, 2008 Posted November 21, 2008 Can someone give me rough idea of licensing cost for Xen Server.
powdarrmonkey Posted November 21, 2008 Posted November 21, 2008 Curses - is the open source version of Xen limited to just two cores, then? Yes. Each guest has limits and you can only have two guests running at a time IIRC. We have five licenses because of this limitation.

Each guest has limits and you can only have two guests running at a time IIRC. We have five licenses because of this limitation. I think Citrix have muddied the waters here. Xen is being sold by Redhat as an enterprise virtualisation solution, it is also available free from other distros Citrix also have a free version of xen called express which they have crippled to try and get us to pay for the 'full' version. .
CyberNerd Posted November 21, 2008 Posted November 21, 2008 Here is some marketting blurb for XEN: The flagship is now RHEL 5 Advanced Platform, which is licenced for an unlimited number of virtual instances on an unlimited number of CPUs and sockets, so workloads can be moved around the data centre as needed. It also includes a clustered file system and logical volume management but costs the same as the more limited RHEL 4 Advanced Server release, the company said. It seems it is only the Citrix version that is crippled, not other linuxes.
wesleyw Posted November 21, 2008 Posted November 21, 2008 Citrix Xen Server has three versions Standard <£500, Enterprise<£1200 and Platinum <£2000 I believe enterprise has live migration available. Citrixs Advanced Licenses cost under £135 each for schools however you don't get certain extras such as reporting and Resource Management, CPU and Virtual Memory optimisation (25% more users per server) that you get with enterprise, application streaming to fat-clients et cetera. Wes
sammy Posted November 21, 2008 Posted November 21, 2008 Hi Guys, Wes is pretty much there with the prices although they are list rrp so you guys as education get a fair bit off. Also Wes is correct about the Live Migration too which is available from the Enterprise edition onwards....an excellent feature and Citrix call it XenMotion, in VMWARE its called VMotion, and Virtual Iron call it Live Migrate....just diff names...same thing. Thank god its friday....i can smell the weekend.

Just for completeness, Redhat also call their feature ' live migration' 19.23. Configuring Virtual Machine Live Migration It costs about £35 per server for educational, or free if you use centos.
fafster Posted November 21, 2008 Posted November 21, 2008 What are the licensing costs for Xen virtualisation under RHEL?
CyberNerd Posted November 21, 2008 Posted November 21, 2008 What are the licensing costs for Xen virtualisation under RHEL? You need to buy the 'enterprise' version. It costs about £35 per server educational. If you want clustering (which you probably will for HA) you need to get the 'advanced' version. not sure about how much that costs, but it's free if you use centos.

Wes Cheers, when you consider VMW makes you go for their most expensive package to get VMotion this looks like good value.
armadillo Posted November 26, 2008 Posted November 26, 2008 Hi, does anybody know the cost of citrix on a blade server? as we've been quoed £23K, is that reasonable? Tthanks in advance.
sammy Posted November 26, 2008 Posted November 26, 2008 Hi Armadillo, I can certainly check out the Citrix licensing for you and make sure its correct. Let me know what you are trying to achieve.
Ric_ Posted November 27, 2008 Author Posted November 27, 2008 Hi, does anybody know the cost of citrix on a blade server? as we've been quoed £23K, is that reasonable? Tthanks in advance. Seems rather high but it depends what you are talking about... If you are talking about XenServer (the server virtualisation product) then you should be paying about £1200 per blade. If you are talking about XenApp (the thin-client-type product) you are talking £100-£120 per concurrent connection license. Then there's XenDesktop (the desktop virtualisation product) but I'm unsure of the licensing costs for that.
