Between 24-128GB of physical memory (DRAM) in each Pivot3 Acuity node is assigned to the local Pivot3 Virtual Storage Controller (VSC) and as such is not available to the hypervisor software (ESXi).
The local Pivot3 Acuity VM can be assigned more memory, however there is little to no benefit to performance by doing so.
By default, 24GB of the memory (DRAM) that is assigned to the local Pivot3 Acuity VM is used as GlobalCache.
GlobalCache: A high performance cache that provides an initial landing point for data as it is passed from the NVMe PCIe flash tier to the erasure coded persistent storage tier (HDD or SSD).
