- MasPar Introduces High-Performance I/O
-
- Sunnyvale, Calif., September 9, 1992 - MasPar Computer Corporation announced
- today a major advance in I/O performance for its MP-1 family of massively
- parallel processor (MPP) systems. The new product, SuperStripe I/O,
- consists of a new high-speed I/O channel, a one Gigabyte solid state disk,
- and a new high performance disk array.
- "Today's announcement breaks one of the most difficult bottlenecks to
- MPP system throughput," said Jeff Kalb, President and CEO of MasPar. "I/O
- has traditionally been the problem no one likes to talk about. But MPP
- really puts the spotlight on the need for I/O matched to high compute
- performance. With our new channel, solid state disk, and disk array, we
- can give our customers the highest performance and most flexible I/O system
- of any MPP supplier."
-
- SuperStripe I/O
-
- The new MasPar I/O system is capable of up to one Gigabyte per second of
- throughput to the processor array and MasPar's new SuperStripe I/O technology
- is at the center of this new level of performance. Building on the technique
- of "striping," first used broadly in disk arrays, MasPar has carried the
- concept throughout the I/O system. Data striping starts with the new
- 42 Series disk array, and extends through the 200 Megabyte per
- second channel, all the way to the solid state disk which stripes data
- between multiple memory modules and any of the 16,384 processors in the MP-1.
-
- "While striping as a technique to build high performance peripherals from
- commodity components is well known, MasPar is the first to build a complete
- I/O system around the idea. By combining proven ideas with our contribution
- of the highest performance channel in the MPP market, we are able to deliver
- outstanding throughput all the way from external peripherals to the processor
- array," Kalb said.
-
- Extremely Flexible
-
- The combination of disk array, high speed channel, and solid state disk
- combine to provide a new set of I/O features matched to the unique
- requirements of massively parallel architectures. For example, the one
- Gigabyte I/O RAM can be used to overlap compute and I/O, as a global
- shared memory for the processor array, or as a solid state disk with standard
- UNIX file structure. In addition, as data moves to the processor array, the
- I/O system transparently performs extensive data manipulation to ensure
- that the proper data arrives at the right processor in the right format.
- For example, if different byte ordering is required, the I/O system
- automatically makes the conversion. All of these conversions and place-
- ments are performed at the maximum speed of the I/O system - one
- Gigabyte per second.
-
- Integrating the new I/O system seamlessly into the system software and
- high level languages was a major objective, and the SuperStripe I/O
- system is fully integrated with both system software as well as Fortran
- and C languages.
-
- High Speed I/O Hardware
-
- The new MasPar Channel I/O Controller is the central controller of the
- MasPar I/O subsystem, managing transactions between the processor array
- and devices attached to the 200 Megabyte per second MasPar I/O Channel.
- The MasPar IORAM Modules provide a large (up to 1 Gigabyte) RAM buffer
- space for I/O transactions, allowing data to be cached for transfer to
- the processor array at speeds up to one Gigabyte per second. Data can
- be transferred between the IORAM and other devices attached to the
- Channel at speeds up to 200 Megabytes per second.
-
- High-Speed Solid State Disk
-
- Using the data-parallel UNIX I/O software, MasPar IORAM Modules can be
- configured as an NFS-mountable Solid State Disk, providing an easy-to-use,
- local high-speed storage system that can accelerate programs running on
- the MasPar system at speeds of up to one Gigabyte a second.
-
- The MasPar Channel I/O Controller is priced at $34,000. IORAM modules
- start at $35,000 for 32 Megabytes, and $72,000 for 128 Megabytes. The
- I/O system can accommodate up to eight I/O RAM modules. These products
- are available immediately.
-
- MasPar's High-Performance RAID Disk System
-
- The new 42 Series MasPar Disk Array (MPDA) announced today supports the
- NFS protocol and provides a UNIX-compatible file system which can be
- accessed directly from the MP-1 or from other systems on the network via
- Ethernet or FDDI. The storage system has a sophisticated fault-tolerant
- mechanism that assures recovery from disk failures should they occur.
-
- The 42 Series MasPar Parallel Disk Array is available in formatted
- capacities of up to 132 Gigabytes and throughput speeds of up to 72 Mega-
- bytes per second. The MasPar array architecture is designed to scale to
- over 500 Gigabytes of storage capacity and more than 200 Megabytes per
- second throughput.
-
- The 42 Series Arrays extends the capacity and performance range of MasPar's
- Parallel Disk Array offering, building on the experience gained with the
- first and second generation products. To date, MasPar has shipped more
- than 50 parallel disk arrays for use with its family of massivley parallel
- computers. Key features of the new 42 Series include:
-
- % High-Performance: Up to 72 Megabytes per second peak and
- 48 Megabytes per second sustained transfers;
- % NFS compatibility: Accessible from anywhere on the network;
- % Design integrated into the entire SuperStripe I/O system,
- enabling buffered data transfers to/from the processor array
- at more than one Gigabyte per second;
- % Extensions to UNIX to support a Terabyte file system
- (UNIX limit is two Gigabytes);
- % Disk architecture scalable to over 500 Gigabytes of data storage
- capacity and 200 megabytes per second of throughput;
- % Up to 132 gigabytes of data storage capacity supported immediately.
-
- Sustained Performance, Pricing and Availability:
- Breakthrough Pricing of $9.50/Megabyte
-
- The 42 Series Parallel Disk Arrays deliver sustained performance to a
- UNIX file system of up to 48 Megabytes per second at a breakthrough
- price of $9.50 per megabyte, which further strengthens MasPar's leader-
- ship position in delivering high-performance RAID disk arrays for
- massively parallel computers. The 42 Series Parallel Disk Arrays provide
- storage capacity ranging from eleven to 132 Gigabytes, with U.S. pricing
- starting at $185,000. The 42 Series MPDAs will be available during the
- fourth quarter of 1992.
-
- MasPar Computer Corporation, founded in 1988, manufactures, markets, and
- supports affordable, high-performance massively parallel computer systems
- and associated software development tools. MasPar systems speed up the
- solution of large and computationally-intensive problems by an order of
- magnitude at dramatic price/performance improvements over existing
- computer architectures. Located in Sunnyvale, California, MasPar is
- a privately-held company.
