Windows Server 2012 introduced some noticeable improvements to storage in Windows. While in previous versions of Windows Desktop and Server operating systems you had very limited options, such as mirroring, striping and RAID5, Windows Server 2012 has introduced some new fundamental concepts:
- Storage pools. A collection of physical disks that enable you to aggregate disks, expand capacity in a flexible manner.
- Storage spaces. Virtual disks created from free space in a storage pool. Storage spaces have such attributes as resiliency level, fixed and thin provisioning.
Windows Server 2012 R2 has some further improvements where Microsoft added the ability to use different tiers of storage types with storage spaces, for example you can use an SSD tier to perform read and write cache to significantly improve performance.
Unfortunately Windows Server 2012 R2 is still not available in EC2. As soon it becomes available, I’ll complete this post and conduct some testing to see how well it performs. Watch this space !!
