SGI Launches New Mid-Range Altix 450 Servers and Doubles Performance of Altix 4700 Blades

Fueled by Next-Generation Dual-Core Intel Itanium 2 Processors, New Blade

Systems Deliver Dramatic Price/Performance Boosts

    MOUNTAIN VIEW, Calif., June 26 /PRNewswire-FirstCall/ -- Silicon
 Graphics (OTC: SGIDE) today introduced SGI(R) Altix(R) 450, a mid-range
 blade server featuring the revolutionary modular blade design first
 introduced in SGI(R) Altix(R) 4700. SGI also announced it is equipping the
 powerful Altix 450 and 4700 servers with next-generation dual-core Intel(R)
 Itanium(R) 2 processors (code-named Montecito).
     The new Linux(R) systems will deliver double the performance of today's
 award-winning Altix(R) servers, while drawing less power and offering more
 density and flexibility for demanding, data-intensive applications.
     The new SGI(R) Altix(R) 450 bolsters SGI's mid-range offerings with up
 to 2.5 times the system performance of the current Altix(R) 350(R) server
 at a lower cost. With dual-core Itanium 2 processors, SGI also is
 dramatically increasing the performance of its existing SGI(R) Altix(R)
 4700 servers at no extra system cost to customers.
     "Today's announcements reflect not only SGI's dedication to providing
 customers with the best possible Linux blade server performance, but also
 our commitment to leading the market with an entirely new generation of
 blade systems," said Bill Mannel, director, systems marketing, SGI. "With
 Altix 450 and 4700 systems powered by dual-core Intel Itanium 2 processors,
 SGI is providing solutions that offer far greater performance than ever
 before, while leveraging SGI's flexible, acclaimed blade architecture."
     More Density and Performance - But with Less Power
     By upgrading its blade servers with dual-core Intel Itanium 2
 processors, SGI also is delivering on two key concerns of IT managers:
 providing greater Linux(R) server density to maximize floor space while
 reducing power consumption and heat dissipation. The next-generation
 dual-core Itanium 2 processors use 20 percent less power then their
 single-core predecessors.
     For customers, this lowers the cost of owning SGI systems today and
 eases concerns about the financial impact of upgrades and expansions in the
     "The power of next-generation dual-core Intel Itanium 2 processors is
 evident in these new blades from SGI," said Boyd Davis, general manager,
 server platforms group marketing, Intel. "The fast NUMAlink backplane
 allows SGI customers to take full advantage of the advanced Itanium 2
 architecture. As a result, they can rely on SGI and Intel to maximize their
 ROI and keep ownership costs down with a more dense, higher performing,
 lower-power solution."
     With the new systems, SGI also is bringing new levels of RAS
 (reliability, availability and serviceability) to high-end Linux
 environments. SGI's RAS efforts leverage its unique experience in building
 the world's largest and most robust server systems combined with focused
 investments on such features as memory error recovery.
     SGI's New Blades: Density, I/O or Both
     Both the SGI Altix 450 and Altix 4700 platforms are comprised of
 modular blades -- interchangeable compute, memory, and I/O blades for "plug
 and solve" configuration flexibility. The innovative blade-to-NUMAlink
 architecture enables users to mix and match a variety of standardized blade
 choices, for perfect system right-sizing and highly efficient performance.
     For customers requiring uncompromised Linux performance and energy
 efficiency at the mid-range, the new Altix 450 offers the best value. Like
 the Altix 4700, Altix 450 servers can be configured to maximize density,
 I/O or memory, or mixed to accommodate any workflow. Each Altix 450 system
 can scale to 38 Intel Itanium 2 sockets (up to 76 processor cores) and up
 to 456GB of globally addressable memory. For more information, visit:
     Ideal for HPC environments with demanding data-intensive workloads, the
 dual-core Altix 4700 system scales from 8 to 512 CPU sockets (up to 1,024
 processor cores) and can accommodate up to 6TB of globally shared memory in
 a single system while delivering a teraflop of performance in a
 small-footprint rack. For more information, visit:
     SGI(R) RASC(TM) Technology Takes Workloads Further
     The latest SGI blade servers also are ideal complements to the
 industry's most powerful Field-Programmable Gate Array (FPGA) technology:
 the recently announced SGI(R) RASC(TM) RC100 computation blade. SGI RASC
 RC100 blades can accelerate the performance of many HPC applications by
 orders of magnitude over conventional systems at a far lower cost and much
 smaller footprint. For more information, visit:
     Pricing and Availability
     Based on processor availability from Intel, SGI Altix 4700 and Altix
 450 blades are expected to be available in the third calendar quarter of
 2006. Altix 4700 system configurations start at less than $75,000, and
 Altix 450 solutions are priced from under $15,000. For more information,
