Univ. of Hawaii - ITS Technical Architecture - Brick       

Server Operating Systems

Primary Architect: Steven Sakata

...

This brick divides servers into two categories: Enterprise and HPC.  HPC are those servers that directly support ITS’ High Performance Computing environment.  All other servers fall under the Enterprise category.  (It does not include any operating system that is delivered in an appliance or full stack system.)

 

Experimental

  • HPC

    • FreeBSD (Firewall Appliance)

Strategic (3-5 Years)

  • Enterprise

    • Red Hat Linux

  • HPC

    • CentOS

Tactical (1-2 Years)

  • Enterprise

    • Red Hat Linux 7

  • HPC

    • CentOS 7.3

Containment

  • Enterprise:

    • Red Hat Linux 6

    • Windows 2016

    • Windows 2012

    • Windows 2008

    • Ubuntu 16.04 (Big Blue Button (BBB) web conferencing server)

  • HPC

    • CentOS 6.4 (Lustre)

    • CentOS 6.8 (Compute Nodes)

Retirement

  • Enterprise:

    • Red Hat Linux 5

    • Windows 2003 (InfoEd)

    • Solaris 10 (3 servers)

  • HPC

    • Red Hat Linux (Management nodes only)

 

Emerging Trends

  • Stripped down operating systems to support containerization.

  • There is a trend away from applications getting less reliant on underlying operating systems.

  • “Serverless” technologies are emerging in the cloud and have the potential for greatly changing the role of OS in the future.

  • BBB is poised to scale out to 4 servers, or be moved to the cloud.
