Introduction ® ™ The EMC Atmos platform address customers’ requirements for storage of active content. Atmos 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.

General Operational Information Data protection is accomplished with data replication on multiple servers. The system does not require or support RAID for customer data; data is protected by redundant copies. Servers contain an LSI 3801 simple SAS/SATA HBA for customer data. Servers support hardware RAID1 mirrors for the internal operating‐system drives. Disk configuration is based on ratios of 1:15 or 1:60 per cabinet. No RAID is used, so 15 or 60 physical disks are presented to the operating system. A server failure causes the system to lose access to all drives. There is no caching, so there is no potential for data loss. The system supports email home, depending on customer‐service levels. Disk drives and DAE LEDs can be blinked manually. 1: Introduction General Operational Information...

Hardware Details Data Unavailable (DU) A failure on most system components causes a Data Unavailable (DU) until the component is replaced. This section describes general operating behavior with respect to DU conditions. Atmos software tolerates failed components, and depending on the customer’s policy, the loss or one or more components would not make data unavailable at the system level. For example, if there are three replicas and one fails, the customer’s data would still be available. All Configurations There is one server connected to the DAEs; there is no HA path. The SAS cables contain four lanes of SAS communication. The DAEs contain a single LCC board with no hardware failover capabilities. Promo Code 1 All components in the system contain one power supply. Any power supply failure causes a DU. The SAS cables to the DAEs are serially chained. A failure on the rear DAE causes a DU on the entire server. The switches also could be a single‐point failure which causes a DU. The switches do have redundant, field‐replaceable power supplies.
