| NT File Server | ||
| Component | Quantity | Purpose |
| Processor | Pentium 150MHz | File Server are rarely CPU bound |
| RAM | 48MB | Provides Large disk space |
| Disk Space | 8GB | 1GB for system and the rest 7GB to share in the network (~50 users) |
| Tape drive | DAT 4GB native | to back up entire server with 2:1 compression |
| Network adapter | Fast Ethernet | you want you files fast don't you; if there is a lot of traffic quite an advantage |
| CD-ROM | Two 8X CD-ROMs | file servers are often used as CD-ROM juckbox |
| Special hardware | None | Avoid unnecessary hardware such as sound cards |
| Special Software | None | Avoid unnecessary software such as anything!!! |
| NT Application Server | ||
| Component | Quantity | Purpose |
| Processor | Dual Pentium Pro-200MHz or a 433MHz RISC |
Application server need fast CPUs for responsiveness |
| RAM | 128MB | Provides Large disk space for fast response |
| Disk Space | 6 GB | Hardware RAID 5 provides fast access and security |
| Backup | Near-line optical disk WORM jukebox or Library drive | WORM writes each database record out for permanent archive |
| Network adapter | Fast Ethernet separate adapter for each subnetwork | Bandwidth should be as fast as possible |
| CD-ROM | One 4X CD-ROM | For installation of Applications |
| Special hardware | None | Avoid unnecessary hardware such as sound cards |
| Special Software | None | but you still can install some sort of network monitoring software to track systems |
| NT Internet/Intranet Server | ||
| Component | Quantity | Purpose |
| Processor | Pentium 100MHz | File Server are almost never CPU bound |
| RAM | 48MB | Provides Large disk space |
| Disk Space | 2GB | Web site are rarely this large |
| Tape drive | 2.0GB | Sufficient to back up hard disk |
| Network adapter | Ethernet | good for internet, use Fast Ethernet for Intranet |
| CD-ROM | One 4X CD-ROM | to install software |
| Special hardware | T-1 interface to Internet | Web servers need permanent leased-line, you don't need it for LAN Intranet |
| Special Software | Internet server software | to set up the web server |
| NT Message Server | ||
| Component | Quantity | Purpose |
| Processor | Pentium 100MHz | Message servers have no real-time requirement |
| RAM | 32MB | No large caches |
| Disk Space | 2GB | Sufficient for almost any messaging server |
| Tape drive | 2.0GB | Sufficient to back up hard disk |
| Network adapter | Ethernet | Sufficient for messaging server |
| CD-ROM | One 4X CD-ROM | For installing Software |
| Special hardware | two high speed modems | For dialing into Internet or online message |
| Special Software | messaging software such as MS Messaging or Lotus Domino | MS Messaging is buggy and Lotus Domino will need a lot more then the above |
| NT Remote Access Server | ||
| Component | Quantity | Purpose |
| Processor | Pentium 100MHz | RAS server are almost never CPU bound |
| RAM | 32MB | No large caches |
| Disk Space | 1GB | more then enough |
| Tape drive | none | no use as data is only passing |
| Network adapter | Ethernet | Sufficient for messaging server |
| CD-ROM | One 4X CD-ROM | For installing Software |
| Special hardware | 16-port serial boar with modems | Inbound dial-up RAS may be as few as one or as many as 256 |
| Special Software | none | Nothing special is required |
| NT Firewall Server | ||
| However you can use NT as a firewall I would advise you to use Linux as you can run it easily on a 80486. The security features of Linux are better (just) as well. If you still want to go for it, the hardware requirements are rather low just get a dual Ethernet. Oh, don't forget about the software. Firewall applications are not cheap. | ||
