Monitor Server Modules to Improve Efficiency and Reduce Down-Time
The controller in a module-based rack or chassis system often needs to identify which cards are installed, monitor key metrics, such as temperature, and track hot-swapped units. The 1-Wire® memory, I/O, and temperature-sensor products solve this problem by providing a unique identity for every module in the system, allowing all devices to be interrogated over a common 1-Wire connection.
Benefits of 1-Wire products
- Backplane connector complexity is minimized
- Operating power is derived entirely from the 1-Wire line, over a single twisted pair
- Automatic module detection enables hot/live system insertion
- Wide operating ranges: +2.8V to +5.25V, -40°C to +85°C
- Each part is uniquely identified by a factory-lasered 64-Bit ROM ID
- 1-Wire line drivers can offload 1-Wire communication from the host software
1-Wire Devices for Rack/Blade Servers
|DS28E04-100||Addressable EEPROM with PIO, Sequence Detect||4Kbit||1-Wire||Allows host system to detect physical location of each module.|
|DS2431||EEPROM||1Kbit||1-Wire||Provides module identification and programmable memory.|
|DS28EA00||Digital Thermometer, PIO, Sequence Detect||-||1-Wire||Ensures equipment is in the proper temperature range. Detects sequence without need for DS28E04-100. PIO can be used to power an LED to alert technician when a problem is detected.|
|DS2413||Addressable Switch||-||1-Wire||Provides programmable I/O pins.|
|DS2484||Single Channel 1-Wire Master||-||I2C slave, 1-Wire master||Offloads 1-Wire communication from host software.|
|DS2482-800||8 Channel 1-Wire Master||-||I2C slave, 1-Wire master||Offloads 1-Wire communication from host software. Provides eight physical 1-Wire lines.|
|DS28E25||Secure Authenticator||4Kbit||1-Wire||Provides counterfeit protection and ensures modules are genuine OEM equipment.|
Improve data center security by alerting when an asset is moved or removed; this is a great application for 1-Wire serial EEPROM devices.
To take security a step further, a DeepCover Secure Authenticator can be embedded in each module to provide secure authentication, to ensure that the module is genuine to the OEM.
