The company said it would stop supporting the Windows Datacenter Server Limited Edition software 90 days after it ships the manufacturer version of the Windows .net Datacenter Server. But Microsoft said users who purchase Windows Datacenter Server Limited Edition would receive a free upgrade to Windows .net Datacenter Server.
One use for the new operating system is to prepare users for the .net release. Al Gillen, research director of systems software with IDC said, "Datacenter server customers typically are going to be slow to move to any new technology." He suggested that the interim release provides a way for users migrate to .net technology.
The 32-bit system is a follow-on to Microsoft's Windows 2000 Datacenter Server. Microsoft said it is aimed at users who deploy Microsoft software to manage servers dealing with a heavy load of transactions.
In a bid to demonstrate the scalability of the server, Microsoft released performance figures for SAP. Running on a 32-way Unisys ES7000 server configured with 32 Intel Pentium III Xeon 900 MHz processors and 12 Gb memory, the new operating system achieved 26,000 concurrent SD benchmark users according to Microsoft. The company said on the Unisys machine running Windows 2000 Datacenter server limited edition and SQL Server, SAP R/3 delivered an average dialog response time of 1.97 seconds per request. It claimed this was a world record for the benchmark.
