1. MicroTCA Common Platform For CMS Working Group
Status Report
E. Hazen - Boston University
for the CMS Collaboration

E. Hazen -- CMS Week

3. uTCA Common Platform WG (convened by me at Magnus' request)
Included in scope of this WG
Backplane connectivity (port connections)
Protocols on common ports (TTC / TTS / DAQ)
Crate and MCH specification
Power supplies
Guidelines for AMC designers
Not in scope (but negotiable)
Implementation of MMC, GbE on AMCs and MCH
E. Hazen -- CMS Week

4. DRAFT Draft document Under review by WG 2010-12-04
E. Hazen -- CMS Week

5. Requirements Summary
E. Hazen -- CMS Week

6. Review: uTCA Ports Use for CMS
DRAFT
E. Hazen -- CMS Week

7. DRAFT Review: Fabrics A, B Use
Port 0 is GbE sourced from commercial MCH1
Port 1 – Compatible with Xilinx GTP (<= Gb/s)
DAQ data from AMC to MCH2
May be used also for fixed-latency controls (TTC)
May be used also for buffer status (TTS)
May be used also for auxiliary data (selective readout)
Port 3 – “Low speed” serial LVDS ( Mb/s)
Fixed-latency controls (TTC)
Buffer status (TTS)
Auxiliary data (selective readout)
DRAFT

8. Review: Fabrics D and up
Use not mandated by this WG
Mainly for trigger users
Two options for interconnection
Star connection to tongue 3, 4 of MCH slots
Interconnect passively or with crosspoint switch at MCH
Fixed connections on backplane
Or, a combination:
Ports 4-7 interconnected on backplane
Ports 8-12 routed to crosspoint switch on MCH2

9. MicroTCA Crate Layout Option 1 (preferred) Option 2
12 full-height AMCs
non-redundant power
single-width MCH
i.e. Vadatech VT892
Still under discussion....
Recommend AMC be kept to
“mid-height” profile if possible
Option 2
12 mid-height AMCs
redundant power
double-width MCH
Rear transition modules
evolving xTCA
“physics profile”

10. CMS-MCH Preliminary Design (aka HCAL DTC version 2)
Base configuration has only tongues 1, 2
Base board - “AMC13” with optics and HS links
Clocks board - distributes LHC clock and controls
Mezzanine connector for T3 with IPMI
New custom T1 base board MMC functions (as AMC-13)
TTC optical rx
4x SFP
Cross-over GbE from MCH1 for controls and local DAQ
Optional T3 board Optional (not in std CMS-MCH)
Crosspoint switch for trigger applications
Clocks board Clock / controls fanout T4 T3 T2 T1
E. Hazen -- CMS Week

11. CMS-MCH Preliminary Design
Propose 4 SFP on front panel
TTC / TTS ( Mb/s)
DAQ to S-Link adapter / DAQ upgrade
GbE option if backplane not available
Spare

12. Action Items Draft document (now out for review by WG)
Crate Specification (~done by Greg Iles)
Have quote from Vadatech; working on other vendors
Confirm that commercial MCH have req'd features
Vadatech supports AMC13
NAT supports “update channel” Ethernet
Neither support both currently :(
Research use of eSATA, PCIe
Confirm these are compatible with our configuration
E. Hazen -- CMS Week

13. Action Items (continued)
Acquire VT892 crate for testing
CERN colleagues are now buying ~6 crates
HCAL is waiting for M&S funding
Proceed with design of DTC-2 / CMS-MCH
Milestone: tested/installed during “2012” shutdown
Funding ?

14. A brief word on DAQ & CREMA
CREMA Introduced in June... no meetings so far Scope is evolving
Magnus has asked me to participate in any future meetings as MicroTCA coordinator...
Had several discussions with DAQ hardware folks about future
Still no firm plans, but I am in the loop
