Technical white paper | HP RA for Red Hat Storage Server on HP ProLiant SL4540 Gen8 Server
7
As shown in Figure 4, multiple Red Hat Storage Server volumes can be deployed with one serving as near-line archival to the
other. For example, a Red Hat Storage Server-based object store volume or a drop box volume could use another Red Hat
Storage Server-based volume for near-line archival. The HP and Red Hat solution provides distinct advantages, including:
• Elastic scalability
• Rapid and random file access to ensure speedy access and recovery (faster retrieval and restoration of file data)
• Optional high availability via replication
• Optimized costs for archiving unprecedented amounts of data while minimizing complexities
• Compatibility with industry standards, including support for CIFS, NFS, and HTTP protocols as well as POSIX compatibility
• Reduced backup windows
Figure 4. Red Hat Storage Server running on HP ProLiant SL4540 Gen8 servers can function as an ideal near-line archival solution.
Solution components
Red Hat Storage Server and the HP ProLiant SL4540 Gen8 server represent an ideal technology combination for deploying
scale-out storage.
Red Hat Storage Server
Red Hat Storage Server is software-only, open source, and designed to meet unstructured, semi-structured, and big data
storage requirements. At the heart of Red Hat Storage Server is GlusterFS, an open source, massively scalable distributed
file system that allows organizations to combine large numbers of storage and compute resources into a high-
performance, virtualized, and centrally-managed storage pool. Red Hat Storage Server was designed to achieve several
major goals as described in the sections that follow.
• Elasticity. With Red Hat Storage Server, storage volumes are abstracted from the hardware with each managed
independently. Volumes can grow or shrink by adding or removing systems from the storage pool. Even as volumes
change, data remains available with no application interruption.
• Petabyte scalability. Today’s organizations demand scalability from terabytes to multiple petabytes. Red Hat Storage
Server lets organizations start small and grow to support multi-petabyte repositories as needed. Organizations that need
very large amounts of storage can deploy massive scale-out storage from the outset.
• High performance. Red Hat Storage Server provides fast file access by eliminating the typical centralized metadata
server. Files are spread evenly throughout the system, eliminating hot spots, I/O bottlenecks, and high latency. With the
HP ProLiant SL4540 Gen8 server, organizations can use commodity disk drives and 10 Gigabit Ethernet to maximize
performance.
• Reliability and high availability. Red Hat Storage Server provides automatic replication that helps ensure high levels of
data protection and resiliency. In addition to protection from hardware failures, self-healing capabilities restore data to
the correct state following recovery.
• Industry standard compatibility. For any storage system to be useful, it must support a broad range of file formats. Red
Hat Storage Server provides native POSIX compatibility as well as support for CIFS, NFS, and HTTP protocols. The
software is readily supported by off-the-shelf storage management software.
