![]() But some applications (e.g., databases that don't implement automatic integrity recovery) can't recover automatically and so aren't optimal choices for a clustered environment. If the active server fails, the dormant version on the second server will ideally start automatically. The application runs on one server and is dormant on the second server. #Microsoft onedrive support phone number install#Suppose you install an application on both cluster servers. Some applications are less suitable for a clustered environment than others. The security of having a managed hot standby for each server can justify the incremental cost of configuring two otherwise standalone servers as a cluster.Įvaluate your applications. Each server in an MSCS cluster can run different applications and provide failover for the other servers. Non-business-critical systems can also be good candidates for clustering. If you can occasionally take down your system for brief maintenance, and if your business can tolerate a few minutes of unplanned outage each year, an MSCS cluster might be appropriate. If your business demands a system that is available 24 * 7, or if your business or profile makes you a target for attack, an NT-based solution isn't for you. Therefore, you must evaluate your requirements and environment before you move ahead with MSCS, then decide whether the product will offer sufficient functionality to meet your needs.Įvaluate your business needs. After all, you're still dealing with NT's security vulnerabilities, hotfix reboots, and volume hardware. MSCS clusters can provide high availability, although not to the degree that very specialized-and very expensive-high-end non-NT systems offer. If you're considering an MSCS cluster implementation in the near future, I recommend that you use NTS/E. Most of the information in this article applies equally to Win2K and NT clusters, although concerns that I don't address here might arise from Win2K clustering. Win2K MSCS is nearly identical to the NTS/E version except that MSCS supports more than two servers in a cluster (e.g., Datacenter will support a 4-node cluster). #Microsoft onedrive support phone number windows#MSCS is a component of NT Server, Enterprise Edition (NTS/E), and Microsoft also includes MSCS in Windows 2000 Advanced Server and Win2K Datacenter Server. However, managing a dependable MSCS cluster (i.e., a cluster that offers services at all required times) involves more specialized preparation, implementation, and maintenance than managing two standalone servers. From my experience deploying several MSCS clusters that are achieving near-perfect reliability (i.e., running with only about 0.001 percent of unplanned downtime), I know that you can use MSCS to make NT fault tolerant. Microsoft Cluster Server (MSCS) can deliver excellent Windows NT system availability for a reasonable cost. ![]()
