Add flash capacity where performance and density matter most. The Nimble Storage ES1-AFS SSD Expansion Shelf is a 3U rack-mountable drive enclosure designed for Nimble CS-Series Storage Arrays, giving infrastructure teams a straightforward way to extend installed SSD capacity without changing the storage architecture. With 30.72 TB of total solid-state drive capacity installed and a 6Gb/s SAS host interface, this shelf is built for environments that need predictable expansion and clean rack integration. The 17.2-inch-wide chassis fits standard data center deployment patterns, while the 26.5-inch depth supports organized cabling and service access in compatible racks. This model is a strong fit for teams that value capacity planning, physical consistency, and vendor-aligned expansion. Instead of piecing together mixed hardware, it keeps the storage stack matched to the Nimble ecosystem, which helps simplify procurement, deployment, and ongoing support. For organizations scaling flash storage, the ES1-AFS offers a purpose-built path to more usable capacity in a familiar form factor.
