Hello List, I currently have a home desktop, which I used for running my all VMs on VmWare Server. It good enough configuration to run 3-4 or more VMs at the same time. I have two internal hard disks on desktop. To get decent enough performance from VMs, I tend to run VMs on separate disk than the host disk. But many times, I have left in situation where I don't have access to my small home virtual data centre. So I was looking for a powerful but lightweight laptop for this purpose. Ideally I would love to have VMs on separate disk. But laptop normally don't have enough room for 2 internal disks. And running VMs on external disk over USB2.0 (@480Mbps i.e. about 5 times slower than eSATA drives) will give a dreaded performance. USB3.0 (@5Gbps twice as fast as eSATA) would be good enough. But not many laptops support it yet. Does anyone has any laptop recommendation for this purpose? I had MacBook Pro with 8GB + SSD hard disk in mind. It would cost about £2000 (inc VAT) in UK. Does anyone has any experiences to share of using MacBookPro to run multiple VMs? Desktop Configuration CPU - Intel Core i7-920 (64bit) - single socket with 4 cores, 8 threads RAM - 6GB Disk - Two internal 750GB each SATA-300 (@2400Mbps) drives , 1 external 2TB eSATA (@2400Mbps) drive. Disk 1 - (internal) Host OS and other stuff Disk 2 - (internal) Reserved for running only VMs Disk 3 - (eSATA @2400Mbps ) Used Disk 4 - USB 2.0 (@ Devices Speeds link - http://en.wikipedia.org/wiki/List_of_device_bandwidths#Storage http://en.wikipedia.org/wiki/Intel_Core_i7#Processor_cores Regards, Vishal Gupta http://www.vishalgupta.com
