Details
In Cisco HyperFlex hybrid configurations each storage node has 2 or 3 SSDs.
HX220c / HX220x Edge:
1 x 240GB SSD for boot
1 x 240GB SSD for system
1 x 480GB/800GB SSD for caching
HX240c:
1 x 240GB SSD for boot
1 x 240GB SSD for system
1 x 1.6TB SSD for caching
Fully Distributed Read Cache: All SSD caching drives within the HyperFlex storage cluster form one big caching resource pool. This means that all storage nodes can access the entire distributed caching layer to read data.
In Cisco HyperFlex all-flash configurations each storage node has 8-26 SSDs.
HXAF220x Edge:
1 x 240GB SSD for boot
1 x 240GB SSD for system/log
1 x 400GB/1.6TB SSD for caching
6-8 x 960GB/3.8TB SSD for data
HXAF220c:
