Hello and thank you for taking the time out to read my question and sharing your expertise.
A new client is getting a new server. Their old IT support did not do such a great job. Since they are getting a new server and it's a fairly small office 12 workstations. I decide this would be a good time to rebuild the network as well.
Current Set up:
1 server 2003 sbs sp2 (w/ 2 NIC's)
12 wks. running XP PRO
ISP is Cable BIZ class
They have two modems. 1 for 4 tel. lines & 1 for 4 tel. lines and internet
The internet modem is connected to a Cisco 851 Series Router (owned by cable company)
Then it runs through a WatchGurad FireBox x5 Edge Firewall. From there it runs through the router and to the switch.
MODEM --> ROUTER --> FIREWALL --> SERVER --> SWITCH --> WORKSTATIONS
What we are getting them is:
Processor Intel® Xeon® E5530, 2.4Ghz, 8M Cache, Turbo, HT, 1066MHz Max Mem (WILL CHANGE TO DUAL CORE)
Additional Processor Single Processor Only
Memory 8GB Memory (2x4GB), 1333MHz Dual Ranked RDIMMs for 1 Processor, Advanced ECC, Mirror
Operating System Windows Server®2008SP2, Standard Edition,x86, Includes 5 CALs
Hard Drive Configuration RAID 5 for PERC S300 Controller, 3-6HDDs
Primary Controller PERC S300 3Gb/s SAS/SATA Internal Software RAID adapter
Hard Drives (Multi-Select) 500GB 7.2K RPM SATA 3.5" Hot Plug Hard Drive
Power Supply Power Supply, Redundant, 580W
OS Partitions 80GB Microsoft OS Partition Override
Embedded Management iDRAC6 Enterprise
Network Adapter Intel® Gigabit ET NIC, Dual Port, Copper, PCIe-4
Client Access Licenses 5-pack of Windows® Server 2008 User CALs (Standard or Enterprise)
Internal Optical Drive DVD-RW, SATA, Internal
System Documentation Electronic System Doc, OpenManage DVD Kit with Dell Management Console
Power Cords 2x NEMA 5-15P to C13 Wall Plug, 125 Volt, 15 AMP, 10 Feet (3m), Power Cord
Keyboards, Mice, Displays and Related Devices Keyboard and Optical Mouse, USB, Black, English, with 17 LCD Monitor
Hardware Support Services 3 Year ProSupport for IT and NBD On-site Service
For Firewall: SonciWall TZ 210 Wireless-N (I think this might be an over kill)
Buffalo 2TB RAID1 NAS to image the server.
I was also planning on replacing their outdated 24 port linksys switch (any recommendations)
Exchange will most likely be hosted as well.
If anyone could recommend a good network topology/hardware I would really appreciate it. Your time is valued as always.
