With the provisioning flexibility I wonder if these are internal or external? If internal, seems like they eat a lot of cost if they are never provisioned. If external, how do they keep them as fast as local?
- wmf 12y agoThey're using NVMe, so the SSDs are either really local or at least in the same rack using a PCIe switch. One could imagine that different servers have different numbers of SSDs and when you create a VM with N SSDs they put it on a server with that many.
- runarb 12y agoThat is quit interesting. I am currently looking into seting up a virtual platform that will use SSD disks. Do you have a source I can look at for more info on what SSD setup Google Compute Engine uses?

- justincormack 12y agoNVMe has virtual disk devices, so you can create any number of devices to pass to VMs.
- wmf 12y agoI think pwarner's point is that if a server has 1.5 TB of flash but the customer only purchases 375 GB, that's real money being wasted.
