The Dell PowerMax 8000 is the highest-density NVMe storage platform in Dell's portfolio and one of the most powerful storage systems commercially available. With 7.5 million IOPS per rack and 187,000 IOPS per rack unit at sub-100μs latency, it is targeted at the world's largest financial institutions, telecoms carriers, and government agencies that require storage performance at an unprecedented scale.
The Dynamic Virtual Matrix architecture that underpins the PowerMax 8000 operates on a fundamentally different principle from conventional active/active storage: every director in the fabric can access every drive. There is no concept of a "preferred" path or controller — the matrix routes I/O optimally at all times, and hardware failures are completely transparent to hosts. This is the basis of the 99.9999% six-nines availability guarantee.
SRDF/Metro extends this architecture across two sites — creating a single logical storage system across geographically separated data centres. Hosts at both sites read from and write to their local array; the arrays synchronise writes before acknowledging to the host. A Witness server at a third site ensures automated failover without split-brain risk.
