HP hardware configuration
HP Integrated Lights-Out (iLO)
ProLiant servers provide exceptional remote management capabilities through the HP Integrated Lights-Out (iLO) solution.
Make sure that you connect each system’s iLO to your management network. Some key features that you may find helpful
during OpenStack deployment include the Integrated Remote Console (IRC) and remote reset and power control. Console
access via the integrated remote console (IRC) can be especially valuable during remote network configuration and
troubleshooting. For more information about iLO configuration and features you can go to the general iLO web page at
www.hp.com/go/ilo or visit the support page for your individual server.
Storage configuration
The Controller and Compute nodes in this reference architecture are specified with 4 1TB physical drives. Each server is
configured with an HP SmartArray controller and we will use that to configure the 4 available physical drives into a RAID 5
logical drive of approximately 3.5TB.
The three SL4540 storage nodes are specified with 2 500GB physical disks attached to an embedded HP Dynamic Smart
Array B120i controller that can be configured as 1 RAID 1 logical volume for boot drive. Each storage node also has
additional 15 450GB physical drives attached to an HP Smart Array P420i controller. For the two SL4540 Swift Object
Storage cluster nodes, these 15 physical disks are configured as one 6.1TB RAID 0 logical drive to provide maximum
capacity. For Cinder Block Storage node, these 15 disks are configured as one RAID 5 volume.
Please refer to HP Smart Storage Administrator documents for how to complete storage configuration:

Ubuntu Cloud Infrastructure with MAAS and Juju
There are multiple ways to install Ubuntu Cloud Infrastructure.
• Ubuntu Cloud Infrastructure with MAAS and Juju: our recommended method
• Install Ubuntu Cloud Infrastructure from packages: the hard way
Installation from packages can provide a deeper understanding of how OpenStack components are assembled and interact
but it’s not practical for a medium to large scale deployment. For this installation we discuss how to use MAAS and Juju to
deploy cloud infrastructure on bare metal servers.
