Hi HDS Experts,

I meet another strange problem in VSP, all of the parts performance is very good except the Cache Write Pending Rate, which is always between 30%-40%, while the MPB/FC port/RGRPs are around 10% usage. How and why it happens? and what's the cache allocation logical?

we have 2 CLPR with 150G(70 RG) and 10G(2RG) memory.
