mdrabble Posted January 26, 2015 Posted January 26, 2015 Looking to redesign the current network due to a number of factors and wondered if my fellow edugeekers would take a gander and let know if I have lost the plot or if it all makes sense. I have 3 Hyper V Hosts currently running 2008 R2 with a HP SAN My plan is to reinstall hosts from scratch with Server 2012 R2 DataCenter (Clustered) Somewhere in this mix may be SCCM 2012 edition. Domain Controllers - Server 2012 R2 ======================= DC01 (Physical) - DC, DHCP, DNS, Radius for Wireless Authentication. DC02 (VM) - AD, DNS, WSUS, KMS DC03 (VM) - AD, DNS, WDS & MDT 2013 User Servers - Server 2012 R2 =================== Approx 200 users per year group US01 (VM) - Years 7, 9, 11 US02 (VM) - Years 8, 10, Exam/Controlled Assessments US03 (VM) - Year 12, 13 & Staff Thin Client/Remote Access - Server 2008 R2 =========================== Give users look and feel of Win7 RDP01 (Physical) - Thin client software (VSpace & NComputing) RDP02 (Physical) - MS Remote Desktop & Gateway File/Print - Server 2012 R2 ================= FP01 (VM) - Approx 50 Printer Queues, Staff & Student Shared Documents, Admin Documents MIS - Server 2012 R2 ============= MIS01 (VM) - SIMS.net and related bits Email (Legacy Server) ============== Exchange 2010 (VM) - Mail to be migrated to Office 365 All comments or suggestions welcomed
plexer Posted January 26, 2015 Posted January 26, 2015 I would separate the print server to be it's own device just so if you have any driver issues etc.... you can work on it separately. Ben 1
tmcd35 Posted January 27, 2015 Posted January 27, 2015 Personally I'd forget WSUS, WDS and MDT and have a separate server for SCCM to do these tasks. Failing that I'd put WSUS on its own server and WDS and MDT on another server. I'd also question why separate out the file services? Why not one file server with separate shares for each group? 1
synaesthesia Posted January 27, 2015 Posted January 27, 2015 (edited) As above, you'll have difficulty with that. What happens with year changes? Do you then copy all the files from one server to another? Probably better off simplifying it a bit; staff on one, students on another. Maybe even have replication set up on user areas as a failover?

Iain.Faulkner Posted January 27, 2015 Posted January 27, 2015 Same as above really, i'd keep the print server separate and we have MDT on its own server as well....allows maintenance and restarts without affecting anything else. We currently have our file servers set up to be as below - File 1 - Staff File 2 - Students File 3 - Shared 1
mdrabble Posted January 27, 2015 Author Posted January 27, 2015 (edited) I would separate the print server to be it's own device just so if you have any driver issues etc.... you can work on it separately. I did think about that when looking at the design and tried to keep the number of VMs down - but yes would make more sense to split them Personally I'd forget WSUS, WDS and MDT and have a separate server for SCCM to do these tasks. Failing that I'd put WSUS on its own server and WDS and MDT on another server. I'd also question why separate out the file services? Why not one file server with separate shares for each group? Hopefully getting approval to attend a SCCM training course, so if approved then I will be using SCCM instead of WDS, MDT etc... if no approval then will be using WDS etc.... My thoughts were since DC only dealing with logons requests etc then utilise the server to do additional roles - again to keep the number of VMs down. It does make sense though separating WSUS and WDS etc. As above, you'll have difficulty with that. What happens with year changes? Do you then copy all the files from one server to another? Sorry, my fault for not explaining my thought process properly, yes would be difficult moving users - my intention was to split the year groups between the the different VMs/hosts. The initial design would be for September. Once set up, a year group would stay on that server until they leave. When a year group leaves and archived, the incoming year group would take its place on that server (if that makes sense) Currently have all Staff, Students and Shared Docs on one VM and at times it runs like a three legged donkey especially when students are creating/editing large files. So my intention was to spread the load/traffic between the servers. Edited January 27, 2015 by mdrabble

It does make sense though separating WSUS and WDS etc. The beauty of VM's, you are not limited in the number of servers you can have (accepting appropriate licencing, ram and cpu capacity). I subscribe to the one server one role notion, thus we have about 30 VMs in total here. Even KMS has been spun off to its own server. Also, especially with WDS, if you need to restart the server for any reason you'll be taking down a DC with it. 2
sturgeo Posted January 27, 2015 Posted January 27, 2015 If you plan on using 2012 R2 for your print server check drivers are available for all your printers in both 32 and 64 bit, we had issues with some older printers and 2008 R2 a few years back and reverted back to 2003 in the end. 1
DavetheITguy Posted January 27, 2015 Posted January 27, 2015 I'd totally break this down, I use SCCM 2012 on it's own 2012R2 server (VM), File server on it's own 2012R2 (VM), Print server on it's own 2012R2 (VM), DC1 is Server 2008 (VM), DC2 is physical. Exchange server on 2008R2 (VM), anti virus is on 2012R2 (VM), Microsoft Lync is on 2012R2 (VM), Sharepoint on 2012R2 (VM), Home access on 2008r2 (VM). I have about 20 servers, 2 VM hosts connected via a HP SAN, Physical forefront TMG server, 2 Physical Backup servers (DPM 2012 and VEEAM). 1
mdrabble Posted January 27, 2015 Author Posted January 27, 2015 Thanks for the all the comments and suggestion which have been taken on board and a new revised plan is in my notepad (a paper based one!) For some reason I am finding it easier to write things in my notepad as and when I think of them and also helps as a handy guide When I'm not so full of the lurgy I made find the notepad and put the revised version on here another once over
Patrick Posted February 3, 2015 Posted February 3, 2015 Wouldn't it make sense to put the print server on its own? In you have an issue with it you can power cycle it as needed without taking down the file storage too.
