2. Microsoft Clustering Terminology Network Load Balancing Cluster (NLB) Component Load Balancing (CLB) Server Cluster Compute Cluster

3. Functionality of the different types of MS cluster solutions NLB and CLB are stateless Ethernet based load balancing service, no additional hardware required Server Cluster is a fault tolerant stateful service, networked storage and dual NIC required Computer Cluster is a data compute service, at least dual NIC required

4. Overview of requirements and MS cluster products Operating System of Nodes in ClusterMaximum Nodes in clusterPer Node Network Load Balancing Component Load Balancing (requires Windows Application Center 2000)Server Cluster Maximum Processors Intel Processor Class Supported (b) Maximum RAM (GB) Windows Server 2003, Standard Edition 3212N/A 432, 644 Windows Server 2003, Enterprise Edition 32128 832, 6432 Windows Server 2003, Datacenter Edition 32128 3232, 6464 Windows Server 2003 Compute ClusterN/A 4 64 4

5. Network Load Balancing (NLB) NLB has no status as it is stateless Web, Terminal, and VPN typical services run on NLB Interconnect by MAC address sharing Resources generally application being load balanced only

6. Component Load Balancing (CLB) CLB has no status as it is stateless Web COM+ typical services run on CLB Using NLB as interconnect Resources generally COM+ application being load balanced only

7. Server Cluster Cluster status held by quorum disk, generally a SAN device SQL, Exchange, File, and Print typical services run on cluster Interconnect by TCP and UDP on single network segment Resources generally SAN and NAS devices, IP addresses, hostnames, and applications

8. Compute Cluster One or more head nodes must run Compute Cluster, remaining head and compute nodes can be Compute Cluster or Windows 2003 x64 Remote administration and job scheduling can be run from Windows 2003 or Windows XP Using MS-MPI supporting C, Fortran77, and Fortran90 (version of MPI2, compatible with MPICH implementation) Using PXE for deployment of nodes

9. Sharepoint NLB & Cluster Validation Sharepoint web pages and configuration are pulled directly from SQL. All changes made from the application are seen immediately upon refresh of web pages Sharepoint runs on IIS and is a valid app for NLB (with server persistence set) Sharepoint runs on MS SQL which is a certified application that cooperatively works with the cluster service

10. Sharepoint High Availability Technologies Network Load Balancing – used to keep the virtual web site available in the event of a web server failure Active/Passive SQL Cluster – used to minimize service downtime in the event of a SQL server failure
