We’re currently experimenting with new hardware for our Cloud Servers, HP Enterprise Blade Servers equipped with Dual 10-Core Intel Xeon E5, 192GB of memory and two SAS disks. Storage is provided by a SAN solution, which is connected with multiple 10Gbit links.
We can get about 800MB/s of Disk I/O for one single physical server, which is really promising for our usage. Also 20 Cores provide enough cpu power for multiple instances, without the fear of performance bottlenecks.
If the platform is able to withstand all our performance tests, we will use this setup for further deployments.
