    Re: Number of Servers

    14(+2) physical servers, 530 clients, ~1900 humans or similar

    2 x DC's (+DHCP+DNS)
    1 x Exchange
    1 x ISA+Websense+WSUS
    1 x SIMS
    1 x FMS
    1 x NAS
    2 x Fileservers (i.e. normal WS2003 instead of storage edition)
    1 x Applications/shared storage/SQL Server/print/cruft
    1 x Sharepoint/classserver
    1 x Terminal server (gradually on its way out) (not rackmount)
    1 x Cashless catering database server (not rackmount)
    1 x MOM2000 (not rackmount)
    +(2 x IP Camera servers (not rackmount))

    =14(+2)

    The camera servers are servers, but we don't really manage them as such: they're more like appliances. I can't really get any more servers because I struggled to do that list from memory as it is!

    Re: Number of Servers

    20 servers for me, and you can never have enough, spread every role out , don't put too much load on one machine

    Re: Number of Servers

    Off the top of my head ...

    1x DC (master)
    1x DC (SMS/MOM/DHCP/RIS)
    1x File Server / Veritas BE
    1x Package Server (to be decommisioned)
    1x Web Server / Sleuth / shared storage
    1x mail relay / SWS (SWS to be removed soon) / firewall logging
    1x Applications / Print server
    1x Sims.NET / admin file server
    1x FirstClass (being removed and changed to a file server / Terminal Server)
    1x Smoothwall (just in, not yet in full use)
    1x Library server
    1x QCA
    1x Apple
    1x Development (presently LNM)

    To arrive in the next few weeks
    1x Exchange
    1x DC (the SMS / MOM box will be demoted and RIS moved)
    1x Terminal Server

    I make that 17.

    Most machines are running some form of SQL (MSSQL, MSDE, SQL Anywhere, MySQL) because different applications that are networked require a database. It tends to be this that means we can't stick anything else on and that we need a new box.

    After I have finished playing with LNM before Spot starts on the new domain we will be looking at Virtual Server again to put a number of applications onto the same box that would not have been possible. If that works then we may spend time looking at VMWare and so on to do the same.

    Re: Number of Servers

    What I find interesting is that most sites have 2 or more DCs (and someone said that you must have at least two). Once again, we swim against the tide - we only have one. I know that MickeySoft say that you should have more than one, to handle machine failures and load balancing. Machine failures (both hardware and software) are far less frequent now than even 5 years ago, so do we REALLY need more that one DC? Also, I've never seen a DC stressed by excessive numbers of logins, but perhaps that is because I'be never worked at a really huge M$ site.

    Re: Number of Servers

    I think that two is usefull, as its a really quick way of keeping it alive if you have problems, just think, you can live without a printserver for a day or so whilst you repair it, but your whole world dies without Active Directory now a days, so in my mind its good practice to have two.

    I can't say I've ever tried to get a domain going again that only had once DC that is now dead. I'm quite sure I don't want to find out! I have both dcs running dhcp (50/50 split), dns, gc, wins, ad. If one fails every other settings for the servers and clients means they can continue to function with no loss of service. Also means I can patch and do a quick reboot one at a time with no real issues for the clients.

    Re: Number of Servers

    Hmm. Lets see now...

    Root domain DC and BDC (2 Servers)
    Student domain DC and BDC (2 servers)
    Staff domain DC and BDC (2 servers)
    Primary file server
    Application and printer server
    SIMS server
    Bromcom server
    Ghost/AV/General Crap repository server
    Terminal Server
    2 Proxy Servers

    That makes 14 I think. The SIMS server is due to be replaced within the next two months and we'll be adding a server for the learning platform, whichever one we decide to go for.

    Fun fun fun

    Re: Number of Servers

    I'm with @openhgs on this. One DC is all we have too and it works fine. If that box dies, we have no CMIS either, but in the last two years the box has only been down twice as a consequence of hardware. Both times were when I resited it. We get CMIS issues but these are application problems and so no amount of DCs will resolve them.

    We don't use Active Directory either. Microsoft say you have too, but don't believe em! W2K works fine without using it. It *might* be called "Active Directory Users & Computers" but it is the same as existed on NT4.

    Its not about one DC working well, its about when it doesn't! I'm not sure I see the point of using Windows 2000 server or above without active directory, you lose all of advantages over nt4. You may as well save some money and use samba.

    Re: Number of Servers

    We're currently running 13, but this is likely to grow as we develop more services and improve disaster recovery and content provision.

    1. SIMS (and soon PARS)
    2. Domain controller and 3 years of students data
    3. Domain controller, 2 years of students data, public files and QCA testing
    4. domain controller, staff data and staff public files
    5. Backup server
    6. school database server
    7. Succesmaker and Eclipse server
    8. Print server
    9. IT apps, drivers and IT database system (something I'm implementing across school for management of desktops and resources, etc)
    10. Second IT server that currently just handles RIS installations
    11. ISA server - provides web access through LEA and ADSL, plus VPN access for tech staff. Also has Websense filtering - makes our life so much easier for blocking/unblocking websites
    12. Frogserver - the school VLE
    13. Reporting server. Primarily used for Websense web filtering reporting, but also has 3Com network supervisor running on it

    All are running Windows 2003... except frogserver, which has LiSUX on it.

    I reckon by end of year we could be at around 16 servers... looking at adding a media server, second backup server for improved disaster recovery and possibly a development server.

    Re: Number of Servers

    Ok here goes, the contents of the countries biggest schools server room And there are only 14 servers.

    Armadillo - FMS And Alice (library)
    Aardvark - ISA
    Alewife - MIS
    Antelope - ILS (Succesmaker enterprise) Was Sophos server but couldnt cope
    AyeAye - Print
    Axlotl - Backup + DC
    Appgate - VPN
    Contentcache - Caches content
    Cougar - DC, DNS, Staff data, Ranger, QCA
    Cheetah - DC, DHCP, Student data
    Caracal - VLE, Sophos enterprise
    Emu - Exchange and intranet
    TLMSData - Access control

    This lot cater for 3000 students (3400 from Sept) about 500-600 staff, A leisure center, and a theatre. It is supported by a team of 6 which includes 3 techs whom are leased out to feeder schools for a couple of hours each day, And a dedicated MIS support person. Structured like this, IS Manager, Network manager, Senior tech and then 3 techs

    We have Approx 400 laptops and 500 desktops.

    Dont laugh but we have not VLAN'd yet, and are looking to consolidate all our sql servers.

    Other than our VPN running Sun Solaris we are M$ all the way.

    @ DanIT, dont you think you could thin that lot out a bit?
