Product and Performance Information
TLC (tri-level cell) contains 3 bits per cell and QLC (quad level cell) contains 4 bits per cell. Calculated as (4-3)/3 = 33% more bits per cell.
4 nodes vSAN* Cluster – 1 node system configuration: Server model: Intel Purley S2600WF (R2208WFTZS); MB: H48104-850; CPU: Dual Intel® Xeon® Gold 6142 2.6G processor, 16C/32T, 10.4GT/s, 22M Cache, Turbo, HT (150W) DDR4-2666; Mem: 16GB RDIMM, 2666MT/s, Dual Rank x16; NICs: Intel X520-DA2 10GbE SFP+ DAC and embedded Intel X722 10GbE LAN. All TLC config: 2x Intel® SSD Data Center P4610 Series 1.6TB for caching and 4x Intel® SSD Data Center P4510 Series 4.0TB for capacity storage; Intel® Optane™ memory+QLC Config: 2x Intel® Optane™ SSD DC P4800X 375GB for caching and 2x Intel® SSD D5-P4320 Series 7.68TB for capacity storage. 2 Workload: HCIBench: https://labs.vmware.com/flings/hcibench. Number of VMs: 16, Number of Data Disk: 8, Size of Data Disk: 60 Number of Disks to Test: 8, Working-Set Percentage: 100, Number of Threads Per Disk: 4, Block Size: 4K, Read Percentage: 70, Random Percentage: 50, Test Time: 3600. Results: P4610+P4510 config = 83,451 IOPS @ 6.3ms latency. P4800x+P43220 config = 346,644 IOPS @ 1.52ms latency.
Comparing 3.5’ 4TB WD Gold TB Enterprise class 7200 RPM HDD enabling up 24 HDDs per 2U and a total of 20U and 960TB total to 30.72TB E1.L Intel® SSD D-5 P4326 (available at a future date) enabling up to 32 per 1U and a total of 1U and 983TB total. So 20 rack units to 1 rack unit.
Power, Cooling, Consolidation cost savings. Based on HDD: 7.2K RPM 4TB HDD, AFR of 2.00% and 7.7W active power, 24 drives in 2U (1971W total power) https://www.seagate.com/files/www-content/datasheets/pdfs/exos-7-e8-data-sheet-DS1957-1-1709US-en_US.pdf SSD: 22W active power 44% AFR, 32 drives in 1U (704W total power); Cooling cost based on deployment term of 5 years with Kwh cost of $.158 and number of watts to cool 1 watt 1.20 Based on 3.5” HDD 2U 24 drives and EDSFF 1U Long 1U 32 drives. Hybrid storage based on using Intel® Transforming Learning Course(s) (Intel® TLC) SSD for cache.
Drive replacement cost savings. Calculation: HDD 2% AFR x 256 drives x 5 years = 25.6 replacements in 5 years; SSD: 0.44% AFR x 32 drives x 5 years = 0.7 replacements in 5 years.
Compares 4K random read IOPs and Queue Depth 32 between Intel® SSD D5-P4320 Series and Toshiba N300 HDD. 175,000 IOPS: Measured data from Intel® SSD D5-P4320 Series 7.68TB SSD. 4K random read IOPs; Queue Depth 32. 532 IOPS: Based on Tom’s Hardware benchmarks for Toshiba N300 8TB 7.2K RPM HDD. 4K random read IOPs; Queue Depth 32: https://www.tomshardware.com/reviews/wd-red-10tb-8tb-nas-hdd,5277-2.html. Hence 4K random read IOPS are 329X better.
PCIe* IOPS based on simulated 4K random read, queue depth of 256, performance estimates conducted by Intel for the Intel® SSD D5-P4320 Series/Intel® SSD D5-P4326 Series PCIe* based QLC SSD at different capacities: 3.84TB; 7.68TB; 15.36TB, and 30.72TB. SATA IOPs set to 100K IOPs for all capacity points based on 100K IOPS being the max possible for current competitive SATA base SSDs from Micron. The Micron 5200 Series NAND Flash SSDs data sheet showing a max 4K random read QD32 IOPs of 95K IOPs for 3.84TB, and 7.68TB SKUs.
