Hardware
This small physical device attaches to the front of a Nitro K2 card, encrypts customer data with a unique key, and has a built-in destruction mechanism.
NSK (Nitro Security Key)
What is BIOS
firmware comes installed on all motherboards and is the first process that runs when a server is powered ON. It contains the instructions needed to load basic hardware and initiate POST.
This tool is used to secure a CPU heatsink to the motherboard, and to correctly secure the bus bar to the Bianca module to the correct specification.
Torque Screwdriver
This Leadership Principle starts with the customer and works backwards. A DCO tech practicing this LP would prioritize resolving a server issue quickly because it directly impacts an AWS customer's workload.
Customer Obsession
What is Perfect Positioning?
9-digit alphanumeric code represents the floor, room, row, and position of a rack in newer AWS data
This specialized processor on the motherboard manages remote monitoring of a host and communicates over the Console Network via the IPMI port to the K2
BMC (Baseboard Management Controller)
This web-based tool allows techs to remotely console into a host using just a browser, but it will NOT work without an open ticket.
Dreamscape
There are 2 primary ways for a DCO tech to view a server's output: a local connection using a KVM (legacy), and a remote connection over the Console Network using one of these 2 tools.
Dreamscape and PuTTY?
This Leadership Principle means leaders are never done learning and always seek to improve themselves. Completing DCO Boot Camp modules and pursuing certifications like CCNA are great examples of living this LP.
Learn and Be Curious
This is the current generation of AWS rack architecture that delivers power directly to rack-mounted devices using powershelves and busbars.
Who Made Who (WMW)
What are the 3 heat regualators in any Server?
Thermal Paste, Heat Sinks and Fans
These are the 3 types of "wares" that build upon one another to enable a server to boot up
Hardware, Software and Firmware
Name 3 of the 5 standard PPE items provided to all DCO techs.
cut gloves, safety glasses, composite-toe shoes, hearing protection, and impact gloves?
This Leadership Principle means thinking and acting on behalf of the entire company, not just your own team. A DCO tech who notices a recurring hardware issue across multiple racks and escalates it to Engineering rather than just fixing their own tickets is demonstrating this LP
Ownership
3 components make up a WMW Power Shelf
PSU, BBU, PSC
What is a PDC
Power Distribution Cabinet
What is CoAP?
Constrained Application Protocol, specifically designed for machine-to-machine communication using UDP and boots servers to the Carbon Menu when issues are detected
This ticket queuing web application is used by DCO teams to track server problems, manage workflows, and report shift utilization.
Boost
This Leadership Principle means leaders expect and require innovation and invention from their teams and always find ways to simplify. A tech who automates a repetitive troubleshooting workflow using a script is living this LP.
Invent and Simplify
These are the 2 separate networks that every AWS server connects to within a rack.
Console Network and EC2 Network
The 4 basic components required for POST are?
DIMMS, power source, motherboard, CPU
What is CBP
This comprehensive provisioning system replaced the traditional Ramdisk based approach for managing Amazon EC2 servers and Nitro instances. Its K2 cards securely mediate network access and manage system firmware configuration, including the host's BIOS and Console output.
When is it safe to remove PPE in the Redzone?
Never
