Microsoft Clustering Terminology Network Load Balancing Cluster (NLB) Component Load Balancing (CLB) Server Cluster Compute Cluster
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
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
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
Server Cluster SQL, Exchange, File, and Print typical services run on cluster Interconnect by TCP and UDP on single network segment
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
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
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
