PowerMax systems provide full component-level redundancy to protect against a component failure and ensure continuous and uninterrupted access to information. This non-disruptive replacement capability allows the Customer Support Engineer to install a new component, initialize it if necessary, and bring it online without stopping system operation, taking unaffected channel paths offline, or powering the unit down.
A modular design improves serviceability by allowing non-disruptive component replacements, should a failure occur. This low parts count minimizes the number of failure points.
PowerMax systems feature non-disruptive replacement of all major components, including:
Fibre Channel SCSI
Fibre Channel NVMe
iSCSI
FICON
Embedded NAS (eNAS)
PCIe (back-end)
Flash (Vault)
SRDF Compression
Inline Compression and Deduplication
