Virtualising more server roles and Learning Gateway
We are about to embark on a brand new Sharepoint VLE solution and I want to invest a bit on our backend at the same time. We been Sharepoint for the last 12 months but haven't been able to build it as fast as we would have liked and require outside support to assist us.
My biggest gripe with the network at the moment is I think the DR setup could be a lot better, the school have recently purchased an office block about 1/2 mile down the road for additional office space. We currently have a small network of about 30 machines over there and the two buildings are connected via a point to point Motorola wireless bridge. I want to make use of this building to aid in disaster recovery.
I like the idea of Virtualising Servers, we recently have virtualised our Web and Proxy server using VMware ESXi and have purchased the foundation/vmcenter pack on top of this. This is running on 2 separate hypervisor nodes and then are connected to an iSCSI NAS box (Overland SNAP Server 520) which has terrabytes of storage.
I wanted to know what options I have with developing a backend which can replicate between 2 sites, the same data, if one site is playing up i can reroute all traffic to the other site or do it in a way that the main building is the primary, if someone terrible happened at the main building all traffic could go from the office building. I know I dont have the great features of VMware enterprise where it does live migration but I happy to do this manually in this type of scenario. Also is there a way it can load balance if I went with option 1. What type of hardware would we need to invest in at the second site?
We don't have a SAN and use the SNAP server as our main storage, it seems to be able to serve files out ok but it could be better during peak times and we rely a lot on this device not going down (so far we have been ok) but I am worried that we are over reliant on it and want to change things. I am thinking as part of the VLE project if it would be worth migrating all information to a SAN and then use the SNAP server as a backup server. Would other members recommend a SAN or should i stick with the SNAP?
Also am I taking a risk by asking the company we choose for the VLE to virtualise our sharepoint VLE/SQL? At the moment there isn't much load on our 2 new HP DL380's with 1 quad core and 8gb ram but one is running the web server VM and the other is doing the Squid proxy VM, both are connected to SNAP server for storage. I was thinking of adding further VM's to these nodes.
On top of the other developments we have 2 exchange servers (1 staff and 1 students) both running standard edition and the staff email server is nearly 4 years old. I was thinking of migrating all staff mailboxes to the students exchange server. Can I do this? is there any limitation with standard where I can have 2 separate mailbox groups?
Also have any schools virtualised their MIS systems (SQL), Facility CMIS and eportal to be precise. We seem to suffer from a lot of memory leaks on this separate server and am thinking of putting this onto a newer server or virtualising it to our DL380s. Any advice from other schools who have already done this would be most appreciated..
Hey Ranj, i like the sound of what your doing but have a question. Why are you not using Hyper-V?
We have all our servers, bar 1 exchange box, on windows 2008 server and hyper-V is awesome not to mention some of the extras R2 will have with it.
We have virtualised a DC, fileserver, SQL server and all seem to be running smoothly.
I have not tried virtualising sharepoint yet as we have a DL360 (box1) running sharepoint and a DL360 (box2) as our web server / sharepoint web front end which connects to our farm on box1.
It would be nice to see what you have done with sharepoint as i am the developer here and the only one that really does anything with sharepoint (started from 0 knowledge 3 months ago).
Sharepoint now runs our website / staff intranet / student intranet and we have sites which include a helpdesk / room booking and / resource booking as well as a slightly customised master page (still not bothered getting into the visual stuff yet) we are also trying to setup sharepointLMS from e-learningforce (google them) as it seems like it ticks all our boxes and version 2 looks good (from the demo at BETT).
Anyways, get in touch if theres anyway we can help each other

If you want to run a Linux-based server, DRBD. It's free to use, well documented, and you can assign it specific network interfaces to use for replication traffic, so you can have a dedicated connection just to synch your two locations. You could then run VMWare on top of Linux, running your Windows VMs on top of that.
We have a 4GB machine running 3 Windows-based VMs, no problems. For the Sharepoint VLE/SQL I'd make sure the SQL server gets assigned its own disk partition or RAID volume to do with as it wants.
Once I thought there was nobody that I can not forget.But I have known forgetting one person is not an easy since I met you. Our love is just akin to the sight you went through. To you, I may be only one passing traveler, but to me, you are my best love. Thanks to having loved, I can not detest you. No matter what the result is, I will not detest you.Thank you for having me for those days. It is a happy to be loved by you although I can not be together with you.I will remember what you have given to me. Bless for you, my dear.It is not an interesting story with three persons, so I escaped from this story.You came in my life in a sudden and went in a sudden.I knew you would leave but it was so quick that I hadnít got ready for it.You said if we had learnt each other earlier, we should have got married.You said you had a wrong choice.But my dear, do you know there is no way back?It was the silliest incident that brought Nannette into my life.buy wow gold, I had been in my local supermarket and spent more than I should. When I reached the checkout girl I remarked, wow gold jokingly, that my money was all gone after I had paid for all the articles. On my way out through the main doors a girl suddenly appeared and asked me, wow gold that if I was really short of cash, she was willing to lend me some maple story mesos, in order for me to get home. I was very surprised and she was a rather attractive looking girl maple story mesos. Now, as it was hardly an everyday experience, maple story mesos having a gorgeous girl appear out of thin air and offer me money. maple story gold ,maple story power leveling
