The JMR PSAN bus carries PCI data at full bandwidth across inexpensive twisted pair links to provide both high speed and redundancy-based fault tolerance.
Working with BrightStor ARCserve Backup for storage management and backup, the JMR PSAN solution allows end users to have a truly effective and low cost near line or back up to disk solution.
The PSAN 2U PSAN JBOD product is supplied with dual 450W (N+1) universal input power supplies containing integrated centrifugal blowers which cool all enclosure contents; a quantity of Hitachi Deskstar SATA drives in front-access removable carriers; two power cords; a Windows GUI utility; and a PCI card host controller to provide direct connectivity to P-SAN with user-supplied CAT-6 STP cabling up to ten meters in length.
Patent and Trademark Office on its patent application which details unique design and application elements used in PSAN.
A PSAN/PMMA blend containing 60% w/w PSAN and 40% PMMA (indicated as blend B6040 in the following) was generated by melt-mixing granules of the as-received resins in a laboratory-scale, co-rotating, fully intermeshing twin-screw extruder.
Staining was not necessary because of a sufficient contrast between the PSAN and the PMMA domains.
Since, we are only concerned with a composition of 60% PSAN, at which numerical solution for the coexistence point could be obtained over a range of shear rates, we have not considered other algorithms that may be capable of achieving a solution over the entire composition range.

JMR Electronics will be demonstrating their PSAN

PC or poly(butylene terephthalate) by inclusions of PSAN or PMMA and poly(caprolactam) by particles of PSAN.
To these ends, two series of PC blends were prepared: (i) binary blends with PSAN in the whole composition range and (ii) ternary blends consisting of PC (50% or 40%), PSAN, and poly(styrene-co-methyl methacrylate) (PSMMA).
Screw profile and temperature regimen were optimized in order to achieve good mixing without degradation of PSAN and PSMMA.
