       •   Speed
       •   64bit Speed!
Why the change
  •   Improved OS technology – Windows 2008R2
  •   64 bit Operating System
  •   Memory Cache. Nanoseconds vs. Milliseconds
  •   Improved Web Application Platform
  •   Type 2 database
  •   OpenEdge 10
        64 vs. 32 bit OS

• Memory is increased from 4GB on 32bit
    • 32GB 2008R2 Standard
    • 2TB 2008R2 Enterprise

• Increase I/O
    • DB restore example:
        • 2008R2 245,000 Kbs I/O
        • 2003R2 180,000 Kbs I/O
             • 35% Improvement
The old webspeed placement

                             These two servers spend a great
                                 deal of time on network
Its all about placement
Shared memory and No middle agent

      Skyward Database / Web                                         Connects to Skyward with an Internet Browser
      Monolith CAS / DAS                                             Reads files in PDF format

                                All the skyward programs are using shared memory.
             The WebSpeed Brokers, AppServers and Reportq handle Web requests and processing of Data.

  Skyward Recommendations
For a complete list visit:
     Server Recommendations

•   Skyward supports Virtual Servers using VMware ESX and ESXi.
•   Skyward Servers must be 64 bit Operating Systems
•   Skyward Servers cannot be domain controllers
•   Gigabit network connection required for all Skyward Servers.
•   Fiber Channel and iSCSI SAN storage are supported for Skyward Databases
•   Fiber Channel SAN storage is recommended for the best database performance.
•   A separate Web server located in a DMZ is can accommodate access to web
    products outside the district.
•   Raid 1+0(10) is best, Raid 1 and (Raid 5 VMWare) are supported
                  Server Virtualization
Server virtualization is the masking of physical server resources,
including the number and identity of individual physical servers, processors, and
operating systems, from server users.

    Increases hardware utilization by 50-70%
    Decreases hardware and software capital costs by 40%
    Decreases operating costs by 50-70%

Virtualization products
    • VMWare ESX & ESXi
    •Microsoft Virtual Server
    •**Free Virtual products such as VMware Server should not be used as
    Skyward Servers
    •***VMware ESX and ESXi are the only supported versions for
    Skyward servers
                     Web Server

•Skyward Web Server

   • IIS accesses the Skyward database through a web broker

   • Skyward web applications accessible via Internet Browser

   • Each Web Server Requires an SSL Certificate for encryption
                      Report Server
Skyward Report Server

   • Processes tasks for the web applications (reports, schedule tasks,
   message center, etc)

   • Runs the brokers and services that control the Report Queue

   • Can be configured with IIS or Report Queue File Streaming

   • File Streaming Report Queue Servers do not need IIS / SSL
         • File streaming performs better then redirection.
 Type 2 Storage
– Efficient block formatting
   • Cluster at a time
   • Fewer bi/ai notes written
       – Lets talk about AI (After Imaging)
– Block clustering
   • Alleviates object fragmentation
   • Improves I/O efficiency
– Concurrent Space Allocation
   • Area space Allocation
   • Object space allocation
          Up to 40 % improvement
