Explanation:
EMC Atmos
EMC Atmos supports object-based storage for unstructured data, such as pictures and videos.
Atmos combines massive scalability with specialized intelligence to address the cost, distribution,
and management challenges associated with vast amounts of unstructured data.
Atmos can be deployed in two ways: as a purpose-built hardware appliance or as software in
VMware environments, where Atmos VE can leverage the existing servers and storage. The
hardware appliance is comprised of servers (nodes) connected to standard disk enclosures.
The rack includes a 24-port Gigabit Ethernet switch to provide internode communication.
The Atmos software is installed on each node.
Atmos VE enables users to exploit the power of Atmos in a virtualized environment. It can be
deployed on a virtual machine in VMware ESXi hosts and configured with the VMware certified
back-end storage.
Following are the key features offered by EMC Atmos:
• Policy-based management: EMC Atmos improves operational efficiency by automatically
distributing content based on business policy. The administrator-defined policies dictate how,
when, and where the information resides.
• Protection: Atmos offers two options to protect the objects, replication and Geo Parity:
Replication ensures that the content is available and accessible by creating redundant copies of
an object at multiple designated locations.
Geo Parity ensures that the content is available and accessible by dividing objects into multiple
segments plus parity segments and distributing them to one or more designated locations.
• Data services: EMC Atmos includes the data services, such as, compression, and deduplication.
These features are native to Atmos and can be managed and accessed via a policy.
• Web services and legacy protocols: EMC Atmos provides flexible web services access
(REST/SOAP) for web-scale applications and file access (CIFS/NFS/Installable File
System/Centera API) for traditional applications.
• Automated system management: EMC Atmos provides auto-configuring, auto-managing, and
auto-healing capabilities to reduce administration and downtime.
• Multitenancy: EMC Atmos enables multiple applications to be served from the same
infrastructure. Each application is securely partitioned and cannot access the other application’s
data. Multitenancy is ideal for service providers or large enterprises that want to provide cloud
computing services to multiple customers or departments allowing logical and secure separation
within a single infrastructure.
• Flexible administration: EMC Atmos can be managed via a graphical user interface (GUI) or
command line interface (CLI).
