Faster Time-to-Market for SI, VAR and ISVs
We provide flexible volume per order and lab certification services making it easy for our system integrators (SI), value-added resellers (VAR), and independent software vendors (ISVs) customers to help get their products to market faster.
System Integrators, VARs, and ISVs now have a product capable to provide system level design, testing, for embedded computing products and also extending the products’ lifecycle to allow them and their customers to focus more on marketing their products and less time and expense re-qualifying and re-certifying their products every 2 to 3 years.
IPMI Support
The IPMI (Intelligent Platform Management Interface) is a set of industry-standard specifications for hardware-based subsystems that provide management and monitoring capabilities independently of the host system's CPU, firmware, and operating system. Used together with a BMC (Baseboard Management Controller), IPMI allows a system administrator to perform many different monitoring and management tasks remotely without having to be physically located next to and connected to the system – such as power cycling a server, installing BIOS or firmware updates, and monitoring fan speeds and temperatures. BCM HPC solutions have built-in onboard BMC/IPMI technology with real-time system monitoring and provide preventive maintenance to minimize system downtime and field service cost.
IPMI Advantages:
- Reducing high cost for downtime and repair
- Reducing TTM and development cost for platform management
- Enabling “Always Accessible” management
- Enabling cross-platform manageability across server classes
- Enabling secure remote management
- Multi-OS Support
IPMI Features:
- Server Hardware Monitoring
- Remote Power Control
- Remote Control
- Out Of Band (OOB) BIOS & Firmware Updates
- Asset Tracking
