- 19. Simplifying web-scale systems management with the Dell PowerEdge Embedded RESTful Interface Thank You!
- 20. 20 The rise of REST APIs • Representational State Transfer (REST) has become the leading architecture for APIs • Why is REST the winning method for APIs? – Two words: “mobile apps” - bandwidth efficient, lower processing overhead – Easier to learn, aligned to web technologies • What’s driving demand for REST? – REST fits with DevOps tools and processes, hybrid cloud and virtualization automation – More enablement choices: open source utilities, browser plug-ins, and scripting support Source: programmablew eb.com, 2014
- 21. 21 Redfish enabling technologies • HTTP/HTTPS communications: the Redfish API is accessed using this well-known and highly secure interface. Individual management objects addressed as Universal Resource Identifiers (URIs) • RESTful API: management objects read and written using REpresentational State Transfer (REST) approach with standard HTTP “verbs” such as GET, POST and PATCH. RESTful APIs are a preferred approach for IT automation • JSON data representation: Java Script Notation (JSON) is a lightweight data interchange format designed to be human readable and writeable. JSON uses computer language conventions well known to IT developers • OData data exchange protocol: created by Microsoft and standardized by the OASIS standards body, OData enables standardization of data formats for the management data objects • These technologies were chosen to support the needs for simple, scalable, and secure server management that fits well with modern IT developers’ tools and processes
- 22. 22 Standard Redfish specifications and schemas • BMC infrastructure – View / configure BMC network settings – Manage local BMC user accounts • Discovery – System topology – rack/chassis/server/node • Inventory – Basic server identification and asset info – Simple storage - HDD/SSD – Host NIC addresses • Core server actions – Reboot / power cycle server – Change boot order / device – Set power thresholds • Monitoring – Health state – Temperature sensors and fans – Power supplies, consumption and thresholds – Event notification • Access and logging – Session-based secure access with HTTPS – Serial console access via SSH – Logging methods
- 23. 23 PowerEdge Embedded REST API Dell unique capabilities • PowerEdge Server Configuration Profile support for server configuration • Metadata URL providing XML-formatted description of resources and collections available • Information on all iDRAC out-of-band services – web server, SNMP, vMedia, SSH, Telnet, IPMI and KVM • Configuration of boot source using UEFI boot path • UEFI Device path for storage and network devices • With Dell iSM installed: detailed reporting of LOMs, NICs and network interface details including IP address, subnet mask, and gateway for the Host OS • Expanded storage subsystem reporting covering controllers, enclosures and drives • PowerEdge FX2: Detailed chassis information covering power supplies, temperatures, and fans
