Enterprise-Class Storage Features
The data platform has all the features that you would expect of an enterprise shared
storage system, eliminating the need to configure and maintain complex Fibre
Channel storage networks and devices. The platform simplifies operations and helps
ensure data availability. Enterprise-class storage features include the following:

Channel storage networks and devices. The platform simplifies operations and helps
ensure data availability. Enterprise-class storage features include the following:
•
Replication stripes and replicates data across the cluster so that data availability
is not affected if single or multiple components fail (depending on the replication
factor configured).

•
Deduplication is always on, helping reduce storage requirements in virtualization
clusters in which multiple operating system instances in client virtual machines
result in large amounts of replicated data.

Compression further reduces storage requirements, reducing costs, and the log-
structured file system is designed to store variable-sized blocks, reducing internal
fragmentation.

•
Thin provisioning allows large volumes to be created without requiring storage
to support them until the need arises, simplifying data volume growth and making
storage a “pay as you grow” proposition.

Fast, space-efficient clones rapidly replicate storage volumes so that virtual
machines can be replicated simply through metadata operations, with actual data
copied only for write operations.

Built with Cisco UCS Technology
Cisco is the only company to have built a self-aware, self-integrating system with
a single point of management and connectivity for the entire system. The system is
designed as a single virtual blade server chassis that can span multiple chassis and
racks of blade and rack server–based nodes. Cisco thus is in the unique position of
being able to deliver a hyperconverged solution that can incorporate blade and rack
systems in its architecture, offering greater flexibility than any other solution. You
can optimize your system with the amount of computing and storage capacity that
you need by changing the ratio of CPU-intensive blade servers to storage-intensive
capacity nodes. You no longer have to deploy only appliances.

Cisco HyperFlex HX-Series Nodes
A cluster requires a minimum of three nodes (with disk storage). Data is replicated
across at least two of these nodes, and a third node is required for continuous
operation in the event of a single-node failure. Each node that has disk storage
is equipped with at least one high-performance SSD drive for data caching and
rapid acknowledgment of write requests. Each node also is equipped with up to the
platform’s physical capacity of spinning disks for maximum data capacity. At first
release, we offer three tested cluster configurations:

Small-footprint cluster with Cisco HyperFlex HX220c M4 Nodes: This
configuration contains a minimum of three nodes with up to six 1.2-terabyte (TB)
SAS drives that contribute to cluster storage capacity, a 120-GB SSD metadata
drive, a 480-GB SSD caching drive, and two Cisco Flexible Flash (FlexFlash)
Secure Digital (SD) cards that act as boot drives.
