Microsoft fires up storage-optimised Azure instances Microsoft's decided Azure needs virtual machines optimised for storage, so has given us all the new L-series to play with. They're all running Xeon E5 V3 CPUs and go from four cores, 32 GiB of RAM and 678 GB of local SSD up to 32 cores, 356 GiB RAM and “over 5.6 TB of local SSD.” Microsoft says the new instance type is for “ …
"RAM and disk are typically sold as if a gigabyte is a thousand million bytes."
