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

Executive summary

Organizations of all kinds are struggling with the need to manage growing amounts of data in a cost-effective fashion, even

as they focus on extracting more value from that data. Unstructured data in particular continues to grow rapidly in the

typical enterprise, outpacing the abilities of conventional storage solutions. Enterprises have seen enormous gains in

scalability, flexibility, and affordability as they migrated from proprietary, monolithic server architectures, but storage has

remained a bastion of inflexible technology. The advent of virtualization and growing adoption of cloud models are only

adding to these challenges.

Driven by the need for improved scalability, performance, and faster provisioning at lower infrastructure and management

costs, HP and Red Hat® are collaborating to bring effective scale-out storage solutions to market. Software-defined storage

solutions provide a compelling alternative for serving growing amounts of unstructured data in an approach that scales

easily in multiple dimensions. Scale-out storage increases performance, capacity, or throughput by adding resources

(processors, memory, network interfaces, or spindles) as a loosely coupled system of nodes that work side-by-side, in

parallel.

Red Hat Storage Server running on HP ProLiant SL4540 Gen8 servers offers massive scalability, high performance, and

volume economics for storage of all kinds of unstructured data. In particular, two-node HP ProLiant SL4540 Gen8 servers

equipped with up to 25 disks per node can offer scalable and cost-effective solutions for a variety of use cases, including:

• Creating a large file and object store

• Deploying an enterprise drop box or cloud storage for service providers

• Establishing a near-line archive

Target audience: Technical decision makers, datacenter managers, and storage managers wishing to learn more about

deploying scale-out storage using Red Hat Storage Server and HP ProLiant SL4540 Gen8 servers.

Document purpose: The purpose of this document is to describe a recommended architecture/solution, highlighting

recognizable benefits to technical audiences.

This white paper describes testing performed by Red Hat and HP in January 2014.

Introduction

Red Hat Storage Server offers software-only scale-out storage, which, when combined with the HP ProLiant SL4540 Gen8

Server, provides a unique storage solution that delivers innovative functionality. The all-inclusive Red Hat Storage Server

license includes such features as Monitoring, Tiering, Quotas, Load balancing and failover, Geo Replication and Snapshots

(available June 2014), all of which may incur additional license fees with other solutions. Along with the flexibility of the HP

ProLiant SL4540 Gen8 Server, HP and Red Hat can deliver a cost-effective scale-out storage solution to meet different

workload requirements, whether offering the high capacity requirements of near-line archiving, or high performance for

online analytics.

Storage growth, innovation, and cost

In recent years, unstructured data has been growing at unprecedented rates. Enterprises of all kinds are facing an explosion

of data from diverse applications and technology trends including virtualization, collaboration, business intelligence, data

warehousing, and media. The proliferation of sensors and mobile devices along with the move to cloud computing models

will only accelerate these growth trends. New regulation and data retention requirements further exacerbate the problem.

In fact, according to IDC, from 2005 to 2020, the digital universe will grow by a factor of 300, from 130 exabytes to 40,000

exabytes

with 30.1 billion connected devices by 2020

. At the same time, managing data and exploiting it for new

opportunities has become a top priority for IT organizations as the strategic and tactical importance of data and its analysis

have become apparent.

Driven by this rampant growth, storage costs are having an outsized impact on enterprise IT budgets. While the volume and

use of storage is expected to grow dramatically each year, the price for storage continues to remain high. Per-terabyte

storage prices are not falling as fast as data volumes are growing, presenting a problematic diverging trend for

organizations that must supply and manage large-scale storage infrastructure. For example, IDC estimates that the

investment in spending on IT hardware, software, and services, telecommunications, and staff will grow by 40% between

2012 and 2020.
