Operating System Consulting

is a consulting services company whose team has broad experience in Linux,
Solaris, AIX, HPUX and Irix Operating Systems. Our developers have a strong
background in networking, file systems, performance and related areas. We have an established record of specifying,
designing and implementing custom solutions for a number of corporations.
typically work on turnkey projects which require a mature perspective on thorny
system issues such as multi-processing, stability, deployment, portability and
speed. Often, we initiate and develop solutions from scratch with minimal input
from our clients.
A Sampling of Recent Work
- Performance: QuickPortal has designed and implemented a
TCP/IP offload stack for Solaris. This project required the careful
mapping of the Solaris network framework upon the network framework
supplied by Linux. In this architecture, all network services for Solaris
applications are provided by a dual processor MIPS engine running Linux.
As a result, Solaris applications transparently obtained greater network
throughput and more CPU cycles than otherwise possible.
- File systems: QuickPortal developers have
been involved in porting and maintaining SGI IRIX CXFS technology to
Solaris, AIX and HPUX. This includes IRIX volume management and clustering
technology. Our team abstracted essential kernel interfaces used by CXFS
such as vnodes, kernel threads and sockets to be portable across
different operating systems. We are very familiar with sub-systems and
kernel interfaces for these operating systems.
- Networking: Our principal has led a team of developers at Luminous Networks in
defining the initial software architecture of the Luminous platform. We
have worked on ATM and DLPI
drivers for Solaris. We designed
and implemented a portable AppleTalk stack for AIX, Solaris, AUX
and other platforms. We have specified implementation of FORE ATM drivers
to Auspex NFS servers.
- Concept-to-Customer: We
work on turnkey projects from concept to customer delivery. For example, we designed and managed the
release of HP-UX to Stratus fault tolerant systems. We provided
technical leadership for the project. Our role involved building a
development team from scratch, defining project deliverables, resource
allocation and technical leadership. It also involved keeping management
apprised of project progress and issues of corporate significance.
- Internet/Windows NT:
QuickPortal has designed portions of Intuit’s Quicken Bill Manager
application to be re-branded for different partners. QuickPortal was involved in the
development of the Quicken Bill Manager Web Site. Our principal has
architected the VitalSigns Software's VitalAnalysis product. VitalAnalysis
is a unique web server which collects quality of service (QOS) data from
VitalSigns Software's award winning NetMedic
