Microsoft this week rolled out the latest test-build preview release of Windows Server, known as "build  17074," adding new enhancements to Storage Spaces Direct (SSD).
The company described the SSD improvements in a Wednesday announcement of the latest preview "of  the next Semi-Annual Channel release of Windows Server." This preview  apparently is the successor to Windows Server version 1709, Microsoft's  service-enabled server product, which had its first  semiannual channel release back in October. 
Microsoft effectively has two types of Windows Server  products now: the traditional Windows Server 2016 product and the new  service-enabled one (Windows Server version 1709). The service-enabled product  gets more rapid updates, with major feature updates arriving in the spring and  fall of each year. Windows Server Insider Program participants get to see what's  coming down the pipe from Microsoft, with improvements typically going first to  the service-enabled product side.
Storage Spaces Direct promises the ability to let organizations  tap newer and less expensive devices for storage, including NVMe, SATA and SDD disks. It's  also a big part of Microsoft's so-called "hyperconverged networking" story with  Windows Server. The SSD feature is included in the Windows Server 2016 product,  but Microsoft has previously described having problems with it in the  service-enabled Windows Server product.
In the latest test release of Windows Server (build 17074),  Microsoft is continuing to "expand and simplify the hardware for Storage  Spaces Direct," according to this week's announcement. The highlights  include:
  - Persistent memory support, which helps unlock  low-latency storage possibilities
- Support for "Direct-connect SATA devices to  AHCI controller"
- Cluster Shared Volumes cache support for boosting  virtual machine (VM) performance, and
- The removal of an SCSI Enclosure Services requirement
Microsoft also added deduplication support for SSD and the Resilient  File System (ReFS).
The additions to the SSD feature show that Microsoft is still  working to include it in its next service-enabled Windows Server product. Back  in October, it was revealed that Microsoft had pulled SSD from Windows  Server version 1709 because SSD capabilities weren't at the production-environment  validation level. 
Microsoft also indicated in this week's announcement that it  is enhancing "Azure enlightened Failover Clusters" with build 17074. 
"By making high availability software running inside of  an Azure IaaS VM be aware of maintenance events of the host, it can help  deliver the highest levels of availability for your applications,"  Microsoft explained, regarding this failover cluster support improvement in  Windows Server build 17074.
This build does have a "known issue," though. It  may undergo a timeout failure "while attempting to load the test libraries,"  Microsoft indicated.
