Since implementing Superdome servers, reliable,
remarkable performance has defined the ERP

remarkable performance has defined the ERP
environment. After the recent upgrade to Superdome
servers with Itanium processors, the IT staff saw further
performance improvements and 25% lower Oracle
licensing costs.
Along with moving to the latest Superdome servers,
the staff transitioned from v2 to v3 of HP-UX 11i
to capture performance, reliability, and stability
improvements. “It was part of our strategy to adopt
the latest supported operating system as we had
future expansion of the business in mind. HP-UX 11i v3
showed a performance improvement for Oracle,” says
S. K. Rajavelu, team lead—UNIX and storage.

S. K. Rajavelu, team lead—UNIX and storage.
He notes that HP-UX’s security features are effective.
OpenSSL (open source implementation of the
Secure Socket Layer) mitigates unauthorized access.
Restriction enforcement by the operating system kernel
greatly reduces the performance overhead incurred
with the audit subsystem. Additionally, HP Logical
Volume Manager (LVM) and Mirrordisk/UX are also
proving useful. “They provide value-added operational
support for our environment,” Rajavelu notes.

An improved, global business platform
The staff also notes that the Superdome’s flexible
capacity, via HP hard partitions (nPars) and virtual
partitions (vPars), provides the means to consolidate
and scale up applications. “One of the most
important features of our Superdome environment is
virtualization, which improves utilization and helps
us get the most from our investment,” says Srinivas
Kalayan, senior infrastructure architect.

True mission-critical systems like the ERP system
and Oracle Database instances running Dubai
World require continuous availability and system
protection. Integral in Dubai World’s disaster
recovery strategy are two other HP VSE components,
SGeRAC and Metrocluster. Addressing the availability
and manageability gaps in an Oracle RAC (Real
Application Clusters) cluster, SGeRAC provides
high availability and disaster recovery for the entire
environment in a single solution, while supporting
multiple storage deployment options that improve
manageability.

Metrocluster extends Serviceguard’s coverage by
enabling automatic, bi-directional failover of Oracle
RAC between the primary Port Rashid data center and
the Jabel Ali disaster recovery site. The two duplicated
facilities approximately 25 miles (40 km) apart link by
fiber-optic cable. Metrocluster keeps the databases
functioning well even during extreme conditions, and it
enables the RAC database instances to spread across
the two data centers without any performance impact
due to inter-site latencies.

“We were concerned about performance impacts
after a failover, so we required a disaster recovery
setup to handle site-level failover requirements.
HP Metrocluster and Serviceguard Extension for RAC
integrated with virtualization capabilities all work
together to help us maintain data integrity, flexibility
and deliver the services our customers expect,”
says Nair.

For Oracle ERP and HP software running on other
HP Integrity servers, the staff leverages several other
HP VSE components, including Instant Capacity
(iCAP), Process Resource Manager (PRM), Workload
Manager (WLM), and Serviceguard solutions.

“An HP VSE definitely increases performance,
minimizes space, lowers costs by reducing the number
of physical servers we would need, and makes it
easier to provide services to the business,” Nair adds.

A secure storage foundation
Metrocluster and SGeRAC integrate with
HP StorageWorks XP Continuous Access software
and HP StorageWorks XP12000 Disk Arrays, which
provide data replication and storage capacity.

On the two clusters, HP Services deployed
HP Serviceguard Storage Management Suite to
prevent lengthy downtime when expanding storage
space and make the storage pools easier to manage.
All of these technologies help maintain data access
should a mishap occur with the primary facility.

“Three years ago we implemented RAC with the
Storage Management Suite and we haven’t had
any issues. The HP disaster tolerance solutions work
well with our robust XP Disk Arrays. The arrays scale
well, and the cache feature helps with fast reads and
performance. These products are helping us achieve
our business continuity requirements and smooth
operations,” says Rajavelu.
