== Bonus: Micron vSAN reference architecture ==
[https://media-www.micron.com/-/media/client/global/documents/products/other-documents/micron_vsan_6,-d-,7_on_x86_smc_reference_architecture.pdf Micron Accelerated All-Flash SATA vSAN 6.7 Solution]
Node configuration:
* 384 GB RAM 2667 MHz
* 2x Xeon Gold 6142 (16c 2.6GHz)
* Mellanox ConnectX-4 Lx
* Connected to 2x Mellanox SN2410 25GbE switches
«Aligns with VMWare AF-6, aims up to 50K read iops per node»
* 1 replica2 replicas (like Ceph size=2)
* 4 nodes
* 4 VMs on each node
* 8 vmdk per VM
* 4 threads per vmdk
Total I/O parallelism: 512
* «Baseline» (fits in cache): 121k/178k/249k/314k/486k iops
* «Capacity» (doesn’t): 51k/66k/90k/134k/363k
* Latency is 1000*512/IOPS ms in all tests (1000ms * parallelism / iops)* '''No latency tests with low parallelism'''* '''No linear read/write tests'''
Conclusion:
