Infrastructure Done Right: Part II

Column: From the Trenches

Most tax and accounting firms and other businesses I visit have mechanical
issues that need attention and correction. Your firm, regardless of its size,
is probably no exception. Qualified internal IT personnel as well as outsourced
vendors frequently make incorrect recommendations based on their level of knowledge
or perception that the firm won’t spend the money to do things right.
This year is an excellent time to prepare your network infrastructure for the
future while giving you more flexibility and reliability in day-to-day operations.
When your infrastructure is right, you also have greater productivity, team
member satisfaction and easier disaster recovery.

My hope is that you can use the two-part checklist I’ve provided in
last month’s column and this one to see how your technology infrastructure
measures up to current and reasonable standards. If you are a smaller business,
you will still need most everything listed in the two lists. The items underlined
are specifically for businesses of 50 or more people, but you will notice that
very few items are underlined. Additionally, my team maintains a list of specific
part number recommendations at Look for technology recommendations
on our site.

Look for Part I of this column in the October 2007 issue (also at
where Randy started his checklist that included the following areas:

  • Protection (surge protection, UPS, backup, continuous data protection
    & generators)
  • Network (high-speed communication lines, load balancing firewall, SSL-VPN
    capability, commercial grade power over Ethernet, segmenting, Virtual LAN
    switch, certified CAT 6a cable & wireless access points)

Since many of you are now doing your final upgrades of the year, I have tried
to prepare a simple list of key technologies. Last month’s column specifically
built from the outside communications towards servers. This column works towards
workstations. Here are our best suggestions for the properly dressed infrastructure:


  • Blade or Rack Servers
    Businesses of any size at all should be using rack mount servers
    for more reliability and the ability to repair more quickly instead of tower
    server configurations. However, there is a new generation of server technologies
    that has been introduced by IBM, HP and Sun called blade servers. The enclosures
    accommodate many physical CPUs, drives and network cards in a single cabinet.
    Small businesses can now justify owning blade servers, and will find performance,
    reliability and cost justifications for using this approach.
  • Storage
    • DASD RAID V — Direct Attached Storage Disks
      (DASD) are still very popular, and the minimum configuration we like to
      recommend includes a Redundant Array of Inexpensive Disks (RAID) controller
      with ample onboard
      cache. RAID requires a minimum of three disks to play, and we actually
      prefer an additional hot spare drive in the array at all times, as well.
      The only time we recommend a mirrored pair of drives in a server is when
      the server is attached to a SAN (storage area network) or the server has
      a special purpose like terminal services with no significant data stored
    • SAN — Storage Area Networks are very common
      in large businesses. The cost has continued to drop enough that smaller
      and smaller businesses can afford the technology. Expect SANs to arrive
      in blade enclosures to make them even more affordable for smaller businesses.
      Additionally, new technologies like iSCSI and IP SANs are reducing costs
      over traditional Fiber Channel technologies.
    • NAS — Network Attached Storage is an inexpensive
      way to share a fairly large capacity of disk. Many of these units are
      slower and should only be used for backup or intermittently used files,
      not for day-to-day operations.
  • Virtualization
    Your IT team should be looking at converting your physical servers to virtual
    servers. This technology is working excellently to reduce costs, improve reliability
    and speed up server deployments. We expect even the smallest businesses to
    use virtualized servers over the next few years. Virtualization for both servers
    and desktops is such an important topic that I will cover it in more detail
    in a future column.


  • Desktop
    • Dual-core or Quad-core 64-bit processors.
    • 2.00 GHz 4MB L2 Cache, 1333 MHz FSB.
    • 2GB to 4GB DDR2-667 ECC FBD RAM.
    • NVIDIA Graphics Card 256MB to 512MB On Board PCIe.
    • Integrated 4-channel SATA 3Gb/s controller with 150GB to 750GB 7200
      or 10,000 SATA RPM Fixed Disks or optional 300GB 10K SCSI (SAS) drive
      as a backup add-on.
    • DVD/CD RW+/- Dual Layer (HDDVD/Blu-Ray add $400).
    • 10/100/1000 Gigabit NIC (Wireless Option 802.11a/b/g/n).
    • Bluetooth, 54-1 Multimedia Flash Reader.
    • Front and rear USB 2.0, Firewire, Dolby 7.1 Surround Sound.
    • Dual Monitor Connections DVI and/or VGA.
  • b. Laptop — The Desktop Replacement
    • Size.
      • 17” laptops weigh in at 8+ pounds.
      • 13” – 15” traditional laptops.
      • Portable, Ultra Portable, Ultra Mobile PC (UMPC).
    • ii. Processor.
      • Intel Core 2 DUO Options.
        • T5200 – T7200 (higher the number, faster the processor).
        • Faster the processor, the hotter the system runs.
        • Gamers and heavy video users, the faster the better.
        • Tops out around 2.3GHZ with double clocking (hotter still!).
      • (b) AMD Turion 64 X2 Options.
        • T50 – T60 (higher the number, faster the processor).
        • Same caveats as above: faster = hotter.
        • Runs Vista in Native 64 or 32 emulation.
        • Most programs will have to run in emulation, so plan accordingly
          for business use.
    • Graphics.
      • Look for On-Board Graphics Memory versus Shared Memory.
      • On-Board Memory is better, but it’s more expensive and hotter.
      • 128MB On-Board Minimum – 256BM; 512MB better and hotter.
      • NVIDIA and ATI (AMD) Major players.
    • Widescreens are the standard.
    • Watch for DVI versus VGA External Monitor Port.
    • 2GB of RAM for Vista Business and Ultimate.
    • Blu-Ray/HD/DVD RW+ Drives.
    • 74GB to 160GB SATA Fixed Disk.
    • Flash Drives may be an option instead of fixed disk.
    • Bluetooth (option on many brands).
    • a/b/g/n Wireless Adaptor.
    • 10/100/1000 NIC.
    • No less than 2 USB and 4 is preferred; look for side-by-side, not over-under.
    • ExpressCard instead of PCCard.
  • Monitors
    • 19-inch to 21-inch okay.
    • 22-inch to 24-inch better, and quite affordable.
    • Consider monitors that rotate to a vertical position (portrait vs.


  • Production quality scanners — Fujitsu and Canon
    are the key vendors.
  • Color Laser — Multi-function Device (MFD) worthwhile
    to obtain fax, backup scanning and other paper handling. Clearly HP is the
    winner in this category.
  • Multi-function copier — Stay with the big brands
    like Xerox and Canon. Attach to your network, but only use scan capability
    for backup purposes.
  • Monochrome laser — Go for very fast, network attached
    with duplex capability. HP is clearly the winner in this category, so watch
    for the DN designations (D=Duplex, N=Network).

Other items to consider in order to complete the picture:

  • IP enabled security cameras — Linksys and Sony are
    good choices here.
  • Voice over IP (VoIP) phone systems — Like virtualization,
    this deserves a whole article by itself. Key Vendors: Cisco, ShoreTel, Avaya
    and InterTel.
  • Software.
    • Windows approach — Windows Server 2003, SQL Server 2005, Exchange
      2007, SharePoint 2007, Citrix or Terminal Server OR Windows Small Business
      Server with Citrix or Terminal Server along with Microsoft Office 2007.
    • Linux approach — Red Hat or SUSE Enterprise Linux, Ubuntu and
      Open Office.
    • Virtualization — VMWare ESX server, Xen or MS Virtual Server.
    • Anti-virus suite — CA eTrust, McAfee.
    • Spam control — DoubleCheck.
    • Cellular data connection – Sprint, Verizon and AT&T.
    • Smartphones — Blackberry, Treo, Samsung BlackJack.

Each of the items in this complete list could easily take hours to explain,
and I understand you may not have as much detail as you would like. However,
my chief concerns are that you are

  1. buying sub-standard products to achieve false economy or because of lack
    of knowledge,
  2. selecting a solution in every category where you have a need,
  3. that you are preparing your network infrastructure for the major overhaul
    to come if you are going to transition to Windows Server 2008, Windows Vista
    and to a lesser degree Office 2007. Other applications are going to add additional
    requirements to your infrastructure. Prepare your infrastructure now to be
    ready for the changes in 2008.
