Introduction

The EMC
hardware is a server‐based JBOD storage platform that is optimized to run Atmos software.
Atmos hardware comprises the hardware components necessary to support a JBOD‐based,
bulk‐storage platform. The system optionally supports high‐availability (HA) power end to end.
To support JBOD, Atmos hardware includes 1U Intel‐based Dell 1950 servers with an LSI SAS HBA that
provides the connection to SATA disks.
To achieve the highest density, disk enclosures (disk‐enclosure DAEs) are mounted in a specially
designed 44U Atmos hardware rack. This rack is designed as a standard IT cabinet, holds two DAEs in
a single 3U shelf height, and supports the weight of 360 disks and associated disk enclosures, servers,
and network switches.
Customers connect to the Atmos system over Gbe ports or 10 Gbe ports based on switch configurations.
Customers provide their own interconnect cables.
Atmos hardware has the following features and benefits:
Provides configuration flexibility: you can vary server‐to‐drive ratios.
Uses 1U servers, which allow data‐in‐place server upgrades.
30 drives in 3U.
Leverages CLARiiON UltraPoint design and reliability.
Enables rapid deployment on a petabyte scale, worldwide.
Uses EMC factory‐direct configurations.
Adopts the anytime, anywhere service model (by customers, EMC, or both).
Applies EMC engineering best practices and product quality.
Requires no special power and cooling requirements.
Dense and standard racks, with customizable configurations.
Storage on a massive scale.
Hardware is managed by Atmos software.
