Objective

Leverage the Burke Lab iSCSI device to add to and assist with the migration of the GACRC SAN from 10.0.0.0/8 IP addresses to 192.168.0.0/16 IP addresses. This needs to happen because the SAN VLAN is unable to be monitored. A monitoring node cannot have interfaces on separate networks with the same IP addresses and the 10.0.0.0/8 network is already used on the internodal network (VLAN 40).

Completed

  • Remove Franklin configuration
  • Configure ports in the Thumper Rack for VLAN 31
  • Configure IP addresses
  • Add VMKernel interfaces with 192.168/16 IP addresses to ESX hosts
  • Create LUNs
  • Attach LUNs to VMWare Hosts
  • Begin Migrating VMs
  • Monitor LUN Latency and adjust
  • Gave Burke iSCSI unit definition in Rocks
  • Name: gacrc-iscsi-2
  • MGMT IP address: 172.16.33.114
  • iSCSI Access IP addresses: 192.168.0.1, 192.168.0.2, 192.168.0.3, 192.168.0.4 netmask 255.255.0.0
  • Migrate non-essential VMs to Burke Storage while monitoring latency
  • Provision additional LUNs for high-volume service VMs
  • Migrate zhead/zcluster active VMs
  • Remove LUNs from Hosts and reboot them, one host at a time
  • Change Equalogics IP addresses
  • Reattach Equalogics to Hosts and reboot them, one host at a time
  • Migrate some or all VMs back

=Need to be Completed =

  • Decide based on LUN latency how to proceed with storage provisioning

Notes

  • Use Burke iSCSI as Virtual Machine backup?
  • Use Burke iSCSI as exports for Gluster?
  • Use Both Burke iSCSI And Equalogics for VMWare
