Planning Out A Network
Posted on 2005-03-09
Ok, I've just had a relatively large project thrown at me. I have been charged with coming up with a proposal and price analysis for a network that will be used by a Municipal Government. Unfortunately they have not really given me much information to work with such as exactly what kind of data they want to store and how they want to do the entry. I am not too concerned about that though. They did not tell me the size of their organization either (I guess they think that anyone's assumption is correct...). It is a small city (about 5,000 - 7,000 residents), and so I am coming up with proposals for around 10 to 20 desktops. I am also including in the proposal an Exchange 2003 Server, Web Server, Storage Server (NAS), and 2 Active Directory Servers. Is this overkill?
For the Exchange 2003 Server I am not sure whether or not it would be best to have a front-end and a back-end, of if that would be unnecissary. If I did have a front-end and a back-end I would put the front-end on the same server as the web server. Here is the hardware I'm looking at for these systems right now:
Active Directory Servers (PowerEdge 2850) - Dual Xeon 3.6Ghz, 1GB DDR2 RAM Single Ranked (2x512MB), 3x73GB 15k RPM SCSI HD w/ RAID 5 (Embedded PERC4ei), Intel PRO 1000MT Copper Gigabit NIC, Redundant Power Supply, 24x IDE CD-ROM, 1.44MB Floppy Drive, PowerVault 100T DAT72 36/72GB Internal Tape Backup Unit w/Onboard SCSI, Veritas Server Backup Software, Tape Media Cartridge (5 Pack), Windows Server 2003 Standard Edition
Storage Server (PowerVault 770N) - Dual Xeon 3.2Ghz w/ 2mb Cache & 533Mhz FSB, 1GB DDR (2x512MB), 1x6 Hot Pluggable SCSI Hard Drive Backplane, 2x36GB 10k RPM SCSI HD, 6x146GB 10k RPM SCI HD, PERC4-DI w/ 128mb Battery Backed Cache, 2 Internal Channels w/ Embedded RAID, Intel PRO 1000MT Dual Port Copper Gigabit NIC, Redundant Power Supply, Windows Storage Server 2003
Web/Front-End E-mail Server (PowerEdge 1850) - Dual Xeon 3.6Ghz, 2GB DDR2 RAM Single Ranked (2x1GB), 2x73GB 15k RPM SCSI HD w/ RAID 1 (Embedded PERC4ei), Redundant Power Supply, 2x Intel PRO/1000MT Copper NIC, 24x IDE CD-ROM, 1.44MB Floppy Drive, Windows Server 2003 Standard Edition
Back-End E-Mail Server (PowerEdge 2850) - Dual Xeon 3.6Ghz, 4GB DDR2 RAM Single Ranked (4x1GB), 3x300GB 10k RPM SCSI HD w/ RAID 5 (Embedded PERC4ei), 2x Intel PRO 1000MT Copper Gigabit NIC, Redundant Power Supply, 24x IDE CD-ROM, 1.44MB Floppy Drive, PowerVault 100T DAT72 36/72GB Internal Tape Backup Unit w/Onboard SCSI, Veritas Server Backup Software, Tape Media Cartridge (5 Pack), Windows Server 2003 Standard Edition
Is this overkill? I've never really done something this big before. I am kind of unsure if I really need a second domain controller and a seperate storage server. Maybe The second Active Directory Server should also be the file storage server? Or would it be better to have it seperate like this? I planning on them having a LOT of files.
Thanks for your suggestions.
