8. Spec
The very latest from Intel
12 x Intel® S2600WFT
✓ 384 GiB (12 x 32 GiB) memory
✓ 2 x 28-core future Intel® Xeon® Scalable processor
✓ 1.5 TB Intel® Optane™ DC persistent memory as cache
✓ 32 TB NVMe (4 x 8TB Intel® DC P4510) as capacity
✓ 2 x Mellanox ConnectX-4 25 Gbps
The very latest from Microsoft
✓ Windows Server 2019
✓ Insider Preview, build 17713
✓ Hyper-V + Storage Spaces Direct

9. Mirror-accelerated parity 高速化
Capacity efficiency in %
Storage performance in IOPS
* Mirror-accelerated parity outperforms dual parity, especially in Windows Server 2019, but three-way mirror remains the clear performance leader.
* Three-way mirror has 33.3% storage efficiency. Dual parity starts at 50.0% and goes up to 80.0%. Mirror-accelerated parity is in between.

10. より大容量に
 Deduplication and compression
 Larger maximum scale

11. Dedup & ReFS
Resilient File System (ReFS)
Recommend for Storage Spaces Direct
✓ Detect and correct corruptions
✓ Mirror-accelerated parity
Great features for Hyper-V
✓ Faster VHDX creation / expansion
✓ VHDX checkpoint integration

Data Deduplication
Highly optimized
✓ Outside of IO path (post-processing)
✓ Variable-size chunk store
✓ Multi-threaded
Highly scalable
✓ Volumes up to 64 TB
✓ Files up to 1 TB
