Hardware Replacement Roadmap

From Livedoc - The Documentation Repository

Jump to: navigation, search

This is a scratchpad for listing hardware replacement objectives for each school year. Note that server replacements actually mean a shift from primary production servers to secondary production or testing servers. Secondary servers are retired as they fail or are no longer needed. Battery replacement for UPSes is implied unless otherwise indicated. The schedule may be accelerated in the event that donations or grants put newer equipment into production.

Some items are marked "do not accelerate." This means that they shouldn't be moved earlier under normal circumstances since they would end up getting replaced before they were of a decent age. Extraordinary circumstances include expected budget shortfall or nothing else is a higher priority.

Note that this schedule is very likely too optimistic, based on news of continuing budget cuts in upcoming fiscal years.

2008-09

  • Networking upgrades budgeted (10GbE uplink, new 48-port GigE line cards)
  • "Life support only" on other systems due to tight budget; may consider major purchases later in the year if funds available

2009-10

  • Begin phasing out/trading up older 5U UPSes as the batteries begin to need replacement
  • Replace HP Proliant DL380 G4 servers (fiordland, royal, magellanic) and DL385 G1 server (rockhopper) with 2 new servers (est $15k).
  • Low-priority: consider mid-life upgrades for X4150 and T5120 servers (purchase 8 HW RAID cards + 2 cable kits to accelerate I/O, est $5-6k)
  • Low-priority: upgrade one of the arcturus system boards ($19k)

2010-11

  • Continue 5U UPS upgrade
  • Replace backend Sun T5120 servers (ohare, logan) (est $30-40k, do not accelerate earlier than Spring 2010)

2011-12

  • Finish 5U UPS upgrade
  • Replace HP Proliant DL385 G2 servers (snares, bottom) (est $6-10k depending on whether 1 or 2 servers are purchased)
  • Replace backend Sun V245 servers (dulles, seatac) (est $32k, do not accelerate earlier than Spring 2010)
