Software Components and Operational Guidelines
To better coordinate and integrate OpenStorage Technology (OST) with the DR Series system data storage operations,
the following guidelines list the supported software, required components, optimal performance, and supported
operations:
• OST Media Server Component:
– An OST server component resides on the DR Series system
– For Linux media server installations, use the Linux OST plug-in and the Red Hat Package Manager (RPM)
installer
– For Windows media server installations, use the Windows OST plug-in and the Microsoft (MSI) installer
• Supported Windows-based OST plug-in releases:
NOTA: The DR Series system supports both the 32–bit and 64–bit versions for NetBackup, and the 64–bit
version for Backup Exec.
– Windows Server 2003
– Windows Server 2008
– Windows Server 2008 Release 2
• Supported Linux-based 64-bit OST plug-in releases:
– Red Hat Enterprise Linux, version 5. x
– Red Hat Enterprise Linux, version 6. x
– Red Hat Enterprise Linux, version 10 and 11
• Supported Symantec OpenStorage (OST) protocol:
– Symantec, version 9
– Symantec, version 10
• Supported Symantec DMAs:
– NetBackup: version 7.1 (Windows Server 2003, 32–bit), 7.1 (Windows Server 2008 R2, 64–bit), 7.5
(Windows Server 2008, 32–bit), 7.5 (Windows Server 2008 R2, 64–bit), 7.1 (Red Hat Enterprise Linux 5.x,
64–bit), and 7.5 (SUSE Linux Enterprise Server 11 SP2, 64–bit).
– Backup Exec: version 2010 Release 3 (Windows Server 2008 R2, 64–bit), and 2012 (Windows Server 2008
R2, 64–bit).
NOTA: The Dell DR Series system licensing is all-inclusive, so that no additional Dell licensing is
required to use OST or the optimized duplication capability. The Dell OST plug-in that gets installed
on a supported Linux or Windows media server platform is a free download from Dell. However,
Symantec NetBackup requires that you purchase a Symantec OpenStorage Disk Option license.
Similarly, Symantec Backup Exec requires that you purchase the Deduplication Option to enable
the OST feature.
• Backup, restore, and optimized duplication operations need to be performed via the OST plug-in
• Optimal supported aggregated throughput rates:
– 3 Terabytes per hour (TB/hr) for passthrough write operations
– 4 TB/hr for optimized write operations
NOTA: Passthrough writes are when data is sent from a media server to the DR Series system
without applying any optimization to the data. By contrast, optimized writes are when data is sent
from a media server to the DR Series system after optimization is applied to the data.
