Hewlett-Packard now offers a complete set of HP Netserver AA Solutions that provide
the highest availability possible in a Microsoft
environment. These industry-leading solutions advance system uptime to the highest
possible level—offering nonstop processing, continuous data access, uninterrupted
connectivity, and constant performance for mission critical services.

• user consolidation: reduces cost of ownership

• single system image: leverages hardware, software, and training investment

• no single point of failure: nonstop processing, continuous data access

• runs standard Windows NT and Windows 2000: investment protection

• runs on general-purpose hp netservers: investment protection

• runs off-the-shelf software: reduces costs for special programming

• hp support: provides protection and peace of mind

• hp‘s 25-plus years: put experience on your side

With this offering, HP is the only company that provides solutions for Windows NT or
Windows 2000 and general-purpose servers—solutions that address all the primary
causes of system downtime, including hardware, software, administrative, and
environmental failures. Each solution is complete and includes a comprehensive suite of
hardware, software, and mission critical services. HP Netserver AA Solutions include a
choice of mission critical hardware and software support services, full solution
management, a range of pre-configuration services, and optional application packages.

Using a simple but “bulletproof” architecture, the HP Netserver AA Solution has no single
point of failure. It can withstand multiple failures with no interruption of service to end
users. What makes the solution unique is that it runs with standard, off-the-shelf
applications, on HP Netserver systems—with no modifications to the operating system and
no need for special middleware, scripts, or applications.

simple deployment
and lower costs

The HP Netserver AA Solutions are especially important to companies with mission critical
processing environments where continuous data access is required. Reduced downtime
means higher availability and greater productivity. With architecture that can withstand
multiple failures without an end-user service interruption, HP Netserver AA Solutions offer
the highest level of availability possible—along with greater peace of mind. The solution
is engineered to run in a standard Windows NT or Windows 2000 environment, for
simplified deployment with a lower total cost of ownership.

HP Netserver AA Solutions leverage previous investments in servers, software, and
training while maximizing system uptime and protecting critical data from catastrophic
loss or corruption. In addition, they make it possible to attain a lower total cost of
ownership—for the data center, for disaster recovery scenarios, or for large numbers of
branch offices—by consolidating users, systems storage, management, and backup.
Finally, their ability to run standard applications means that no expensive programming
modifications are needed. No matter what the industry—financial services, banking, or
healthcare—when downtime is not an option, the HP Netserver AA Solution is the one to
count on to protect your business.

how do we do it?

Because HP Netserver AA Solutions use general-purpose servers, standard Windows NT
or Windows 2000 Server software, and unmodified applications, the technology is easily
integrated into mainstream computing environments.

The logical server is created out of an array of four separate servers. Computing
processing is separated from input/output processing, and the array runs simultaneously
on two symmetrical halves (tuples) to ensure that there is no single point of failure. The
I/O processors run asynchronously while the compute elements run synchronously in
lockstep (see Figure 1).

With the HP Netserver AA 6200 Solution, this pairing of servers—called a tuple—can
be located up to 500 meters apart, providing disaster tolerance to keep operations
running even during a fire or other calamity. This unique tuple arrangement provides the
highest level of availability for a platform running Intel
Windows 2000 environment and establishes a solid strategy to cope with both planned
(for maintenance or backup) and unplanned downtime.
