We are planning to move 8 physical servers (dual core 2.x, 8 GB memory, 250 GB HDD, OS: Linux and windows 2003) to VM environment using VMware, but I am worried on VM performance. Our java application needs good IO to perform better
1. To achieve similar performance in VM, how should I configure VMware ?
2. Can I get one big server to accommodate all 8 servers or 2 or 3 servers?
3. How many SCSI interfaces or SAN interfaces should I buy?
