New Trends with VME and OpenVPX - Part 2

  1. 1. New Trends with VME/VPX – Part 2 An historical perspective with a look at the future
  2. 2. Overview Part 1 • VME: how it all started • VME: motivations • VME: electrical features • VME: mechanical features • VME: enhancements (VME64, 2eSST, etc) • VME64: An example - Advme8028 • VME64x + 2eSST: An example - Advme8027 • VME: CPU architectures Part 2 • From VME to VPX • VPX - OpenVPX • OpenVPX: basics • OpenVPX: MultiGig RT2 connector • OpenVPX: planes and profiles • OpenVPX: 2 level maintenance • OpenVPX: an example
  3. 3. From VME to VPX Two disruptive facts: • introduction of high speed, serial links (PCIe, SRIO, etc) • better performing physical layer (connectors, etc) VME has been able to evolve greatly over 30 years, but a new standard matching current and future capabilities is desirable VPX (VITA 46) was designed to allow the introduction of a very flexible standard supporting modern technologies such as multi gigabit links, high performance devices, etc
  4. 4. VPX - OpenVPX VPX (VITA 46) allowed for a lot of freedom  many proprietary mappings for functions on the connectors As a result, VPX is weak on the side of interoperability: boards from different manufacturers might be not mixed in the same system OpenVPX (VITA 65) builds upon VPX a common ground that ensures interoperability OpenVPX is a recent, vital standard that is still being enriched
  5. 5. OpenVPX: basics OpenVPX: • maintains the popular 3U and 6U form factors • new connector: MultiGig RT2 (7-row, up to 6.25Gb/s) • more power: 115W@5V (VME 90W), 384W@12V, 768W@48V • more cooling options: air, conduction and liquid • larger horizontal pitch: 0.8” and 1.0” (with REDI) • differential option for mezzanines • switched fabric • three communication planes + user defined I/O • profiles
  6. 6. OpenVPX: MultiGig RT2 connector Differential pair Ground 7-row differential Backplane footprint Row A Row B Row C Row D Row E Row F Row G Row H Row I 7-row differential Card footprint Row A Row B Row C Row D Row E Row F Row G Differential pair of signals Ground Single-ended signal
  7. 7. OpenVPX: planes and profiles OpenVPX defines 3 communication planes, 1 utility plane, 1 management plane and 1 user defined zone: • Data Plane: High speed links (e.g. PCIe, SRIO ) • Expansion Plane: High speed links (e.g. PCIe, SRIO) • Control Plane: Control traffic (e.g. Gigabit Ethernet) • Utility Plane: Power, clocks, etc • Management Plane: IPMC (independent service processors) • User Defined I/O: A flexible zone (i.e. rear I/O through a transition module) The serial links allow very fast communication and permit different topologies (e.g. the Data Plane is often switched, while the Expansion Plane is often point-to-point). The physical layer supports many protocols (PCIe, SRIO, 10G Eth, etc)
  8. 8. OpenVPX: planes and profiles VPX 1 VPX 2 VPX 3 VPX 4 VPX 5 Switch Switch Expansion plane (e.g. PCIe) Data plane (e.g. SRIO) Control plane (e.g. Gb Eth) Management Plane (IPMC) Controller Utility Plane (Clock, Power, etc) One example: Switch and Management
  9. 9. OpenVPX: planes and profiles OpenVPX uses the concept of “profile”: • Slot profile: • physical mapping and definition of the planes and user I/O as seen from the backplane • Module profile: • definition of the protocols • Backplane profile: • definition of the connectivity across the backplane for each plane • Chassis profile: • Mechanical specs, input power, slot number Slot/ Module profiles can be Payload, Switch/Management , Bridge, Peripheral, Storage
  10. 10. OpenVPX: 2 level maintenance OpenVPX allows great maintenance savings through 2LM (two level maintenance) compared to the traditional 3LM Traditionally (3LM) the Line Replaceable Unit is the Chassis (system). With OpenVPX the LRU is the Module/Card Estimated savings as high as 70% with 2LM Level Type 3LM 2LM Organizational Directly on aircraft/equipment. Inspection/testing/calibrating √ √ Intermediate Off-equipment. Test&repair. Fixed or mobile shops √ X Depot On- or off-equipment. More sophisticated shops. √ √
  11. 11. OpenVPX: an example Eurotech CPU-111-10 is a 6U OpenVPX board with a Quad Core Xeon CPU and a 10Gb Ethernet switch. It supports multiple ruggedization levels, including 2LM
