Elastic Infrastructure is Essential for Cloud and
Software-Defined Storage Environments
Elastic infrastructure powers databases, mission-critical applications, mobile apps,
collaboration, and IT infrastructure. Whether delivered by cloud service providers or
cloud-like software-defined storage solutions, elastic infrastructure requires storage
performance to enable the type of data services that help run enterprises or enable
personal productivity and leisure time.
Storage performance—intensive I/O operations at low response times—is key
to enabling transaction processing that is the basis of cloud-based e-commerce,
micropayments, in-app purchases, and on-premises software-defined storage to run
enterprise latency-sensitive workloads.
Cloud Economics Require Price/Performance
In order for XaaS cloud business models and software-defined storage solutions to
flourish, price/performance must be attainable. Though many varieties of proprietary,
high-performing storage solutions already exist, cloud service providers and software-
defined storage solutions, e.g., hyperconverged infrastructure, architect their systems
to maximize the utility of standard, commodity hardware. The ability to achieve
maximum performance, while achieving price/performance based on commodity
hardware is crucial for cloud delivery on an elastic infrastructure.
Ultrastar DC SA620 SATA SSDs Deliver Economics
to Cloud and Hyperscale Data Centers
To help enable elastic infrastructure for the cloud era, Western Digital offers a SATA SSD
with price/performance capability to enable cloud and software-defined storage to
provide elastic performance for latency-sensitive workloads.
Ultrastar® DC SA620* is a flash-based SATA SSD that offers up to 1.92TB of capacity and
works within existing infrastructure. With data center features to support “mission-
critical” types of data services, Ultrastar DC SA620 delivers a balance of storage
capacity and performance. Delivering up to 52K random mixed 70/30 R/W IOPS and
maximum write latencies as low as 56 microseconds, DC SA620 is well-suited to support
demanding tiers of service at multi-petabyte capacity levels.
Ultrastar DC SA620 price/performance value is achieved by leveraging enterprise-class
performance to enable cloud storage and compute density without the sacrifice of a
low latency QoS or write operations. Ultrastar DC SA620 provides an overall lower total
cost of ownership (TCO) based on the ability to achieve storage and compute density
for elastic cloud computing.
