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

Benefits of the joint Red Hat and HP solution include:

• Flexible deployment. Flexible configurations of compute and storage can be tuned for diverse workloads.

• Drastically lower cost. Massive scalability and density provided by HP ProLiant SL4540 Gen8 servers consolidate power

and cooling and save on space.

• Unstructured data scalability. Scale-out storage software offers a scalable foundation for unstructured data.

• Open and extensible. Extensible storage modules enable new business models without concern for inflexible

infrastructure.

The HP and Red Hat solution provides multi-dimensional scale-out storage infrastructure in terms of both performance and

capacity. By aggregating the disk, CPU, and I/O resources of large numbers of HP ProLiant SL4540 Gen8 servers,

organizations can create large high-performance storage pools. More capacity can be added simply by adding additional

disks. More performance can be added by adding additional server nodes (Figure 1). The unique architecture of Red Hat

Storage Server delivers the benefits of scale-out storage while avoiding the corresponding overhead and risk associated

with keeping large numbers of storage nodes in sync. In practice, Red Hat Storage Server accomplishes multi-dimensional

scalability through:

• The elimination of the metadata server

• Effective distribution of data to achieve scalability and reliability

• The use of parallelism to maximize performance via a fully distributed architecture

Figure 1. Red Hat Storage Server running on the HP ProLiant SL4540 Gen8 server offers both performance and capacity scalability.

The joint HP and Red Hat solution delivers a number of benefits, including:

• Reduced costs. Deploying scale-out storage with Red Hat Storage Server on HP ProLiant SL4540 Gen8 servers allows

organizations to dramatically reduce capital costs while maintaining high levels of performance and availability.

Furthermore, all of the features offered by Red Hat Storage Server are included in one low license fee.

• Outstanding flexibility. The HP ProLiant SL4540 Gen8 Server can be configured with one, two, or three compute nodes,

each with two Intel processor sockets supporting several processor choices, depending on your core to spindle

performance requirements. You can also combine SATA, SAS, and SSD drives within each storage tray, giving you

maximum flexibility in your disk performance. Each node also has the option of supporting Flash IO Accelerators for

additional performance, and the cluster can be networked using 1Gb or 10Gb Ethernet, or via InfiniBand, depending on

the network traffic requirements. All of this offers the flexibility to meet the performance needs of the workload while

maintaining a cost-effective solution.

• Enhanced agility. Red Hat Storage Server can be deployed and scaled in minutes. Because Red Hat Storage Server

automates the management of files and storage nodes, operational complexity is simplified and costs are reduced.

• Increased reliability and reduced downtime. Software ensures the availability of the storage system and its data. Red Hat

Storage Server can replicate data to multiple HP ProLiant SL4540 Gen8 servers, helping to ensure that the system is

protected from faults and that the failure of any individual server does not compromise data access, or the overall

availability of the storage system.
