Technical white paper | HP RA for Red Hat Storage Server on HP ProLiant SL4540 Gen8 Server

• Lower complexity. Red Hat Storage Server running on HP ProLiant SL4540 Gen8 servers provides vastly simplified

homogeneous infrastructure over disparate JBOD systems, while a simplified global namespace helps eliminate

architectural complexity.

• Better user and customer satisfaction. By consistently delivering high levels of performance and helping to eliminate data

silos, Red Hat Storage Server combined with HP ProLiant SL4540 Gen8 servers helps drive higher user satisfaction levels.

The sections that follow describe how the combination of Red Hat Storage Server with the HP ProLiant SL4540 Gen8 server

can be deployed to serve a diverse range of use case scenarios.

Large file and object store

Many organizations use applications that generate a vast amount of unstructured data. Taking the form of either files or

objects or both, these data need to be stored for analysis and synthesis at a later time. Industries as diverse as oil and gas-

exploration (seismic data), telecommunications (data and application logs and billing records), healthcare (imaging and

patient records), finance (risk analysis, compliance, and security data), scientific (gene sequencing and simulations) and

others (rendering, geographical information systems and computer aided engineering) all generate vast amounts of data.

Unfortunately, these unstructured data can accumulate at an exponential rate, causing organizations to continue to react by

adding additional file servers or expensive monolithic NAS devices. Over time, these sprawling configurations can become

difficult to manage and control. In many cases, this file server sprawl can result alternately in underutilization of costly

storage devices or lower performance because of over-utilization of those same file servers and NAS devices.

Large file and object store workloads can be characterized as write once (or write-seldom) with many reads. Average file

sizes can vary from small to large, or from a few kilobytes to several megabytes. The total size of the data store can start

small (from a few terabytes) but will often grow to hundreds of terabytes and continue to grow steadily. The access pattern

generally consists of several concurrent users reading and only a few writing at any given point in time.

Figure 2 illustrates multiple HP ProLiant SL4540 Gen8 servers combined via Red Hat Storage Server into a single volume

that serves as a large file and object store. This approach provides a number of advantages when serving as a large file and

object store, including:

• Elastic scalability

• Elimination of storage silos

• Centralized and simplified management with global namespace technology

• Volume server and storage economics

• Multi-protocol client support for flexible file sharing

Enterprise drop box or cloud storage for service providers

Telecommunication companies, cable operators, and other content providers are increasingly faced with competitive needs

for providing differentiated services for their end customers. As a consequence, many service providers offer their

customers access to free and/or paid storage for storing photos, videos, and other media files that they access via the Web

using a smart phone, tablet, or a personal computer. A similar use case is seen in the enterprise context, where employees

need to reliably and securely store and retrieve files from a variety of devices. Many find that building a reliable back-end

storage infrastructure to meet the agility, cost-point, and versatility of demanding cloud storage or enterprise drop box

deployments is extremely challenging.
