Infrastructure upgrades

  - MSU moved first wave of equipment to Data Center on 14 & 15-Jun.
    Included VMware and all dcache pool nodes.
    Scope of first wave limited by (lack of) availibility of Juniper 10/25G switches.
    Timing and choice of items was made to synchronize with UM site downtime.
    Now have all switches.  
    Next wave will include about half of MSU T2 WNs.
    Last wave(s) need to be synchronized with physics dept servers in neighbor room.

  - UM replaced (almost) all rack switches (repurposing a few old ones).
    Redundant uplinks at 100G.
    Redundant paths to main campus and WAN.
    Mix of Cisco (campus) and Dell (in room) brings some limitations.
    Also replaced all network cabling, using fibers and transceivers everywhere possible.
    Increased KVM coverage.  
    Increased switch serial port access.
    
  - Despite extensive preparations and pre-labeling and sorting of cables,
    and despite the 2 admin, 2 staff and 5 student task force
    and despite UM Networking support
    and despite working over the weekend
    ... this took much longer than anticipated.

  - Status  
    Inter switch infrastructure was finished on Friday
    Solving bugs and problems solved over the weekend.
    dCache back online on Monday.  
    Queues in TEST mode on Tuesday.
    Queues now back on AUTO on Wednesday (running mostly on MSU WNs)

  - Remaining: More cabling of T2 WNs and UM T3
