Hybrid storage pools & tiered storage

• SSDs and HDDs used as different tiers in the same storage pool.

• Windows automatically tracks data temperature and moves them at sub-file level.

• Write-back cache improves performance for

real-world workloads.

• Only hot regions of a file (VHD, database, etc.) need to move to SSDs, the cold regions can reside on HDDs.

• Ability to pin files to different tiers Hybrid storage pool

Tiered space


• SMB file shares for application storage

• Clustered Windows Server configurations expose shared storage

• Highly available, shared data store for SQL Server databases and Hyper-V workloads.

• Increased flexibility, easier provisioning and management.

• Near line rate performance for both small and large IOs.

• Use existing storage and network investments.

• Built-in encryption support.

• Support for planned moves, load balancing, operating system restart, unplanned failures, and client redirection (scale-out only).

• Resilient for file and directory operations.

• All servers involved should have Windows Server 2012 and above.

NIC NIC

Filecopy

• Automatic detection and use of multiple network connections between SMB client and server.

• Helps server applications be resilient to network failure.

• Transparent Failover with recovery of network failure if another connection is unavailable.

• Improved throughput.• Bandwidth aggregation through

NIC Teaming.• Multiple nodes/CPUs for network

processing with RSS-capable network adapters.

• Automatic configuration with very little administrative overhead.
