CSEP Hardware Inventory

The SCEC CSEP Testing Center includes computers, networking, and storage capabilies hosted on USC campus. Below is an inventory of the current CSEP computing hardware, and storage capabilities at USC.

CSEP CURRENT HARDWARE (6/16)

• CSEP-OP
  • 32 core Intel Xeon E5-2670@2.60GHZ
  • 132Gb RAM
  • 13.5 TB total available storage
  • 10.0 TB Used

• CSEP-CERT
  • 32 core Intel Xeon E5-2670@2.60GHZ
  • 198Gb RAM
  • 5.4 TB total available storage
  • 5.0 TB used

• CSEP-DEVEL (Expanded to 4 nodes, same build)
  • Four - 8 core Intel Xeon E5420 @ 2.50GHz
  • 12Gb RAM
  • 0.6 TB storage available

• CSEP-CANTERBURY (UPGRADED)
  • 24 core Intel(R) Xeon(R) CPU E5-2630 v2 @ 2.60GHz
  • 132Gb RAM
  • 16 TB storage available
  • 2.2 TB used

Storage Types

• Data Archive
  • Raw and post-processed catalogs
  • Input parameters for forecasts models, forecasts
  • Evaluation tests results

Storage estimate for new forecasts classes within SCEC Testing Center

• High-resolution 0.1degree Global testing region (per year)
  • 1-day forecasts (KJSS)
    • 5Tb (if using uncompressed original and HDF5 formats of forecasts)
    • 750Gb (if using gzip-compressed original and HDF5 formats of forecasts)
  • 1-year forecasts (KJSS, SHIFT_GSRM)
    • 50Gb (if using uncompressed original and HDF5 formats of forecasts)

• CA testing region (per year)
  • 30-minutes forecasts (ETAS, ETASPPE): 1.5Tb
    • Disable publishing of forecasts to preserve storage on publishing server (only 22Gb disk space left as of 2014/03/03)
    • Switch to event-based testing

Current Storage

Current CSEP usage is at 8.5Tb on operational server. We are also introducing new experiments with models using synthetic catalogs, CSEP might start using much more storage based on how big and how many of synthetic catalogs models will be generating.

Storage Options

 Direct attached, 60TB usable, $13.5k

  Direct attached 220TB usable, $20.5k

 The MD3460 is a SAS array - and you can connect more than one host to it however there is no switch so it is DAS via 12G sas. This array has onboard storage processors with mirrored cache and can be expanded to 60 drives plus up to 2 more 60 drive shelves. Note this array does require 20amp circuit. I have included 3yrs 4hour critical support installation and 96TB raw.

 The MD1200 is a JBOD which uses a Perc Controller to attach to host server. This is for 12G servers only (so R720xd is good). This shelf of drives has 12x3.5" slots so I quoted two MD1200's for raw capacity of 96TB. You can chain more shelves together if you need to expand later. I have included 3yrs 4hour critical support installation and 96TB raw.
