Red hat open stack and storage presentation
- 1. Red Hat OpenStack Platform and Red Hat Ceph Mayur Shetty - Sr. Solution Architect Global Partners & Alliances, Red Hat
- 2. Agenda โ Introduction to Red Hat OpenStack Platform director โ Undercloud โ Overcloud โ High Availability โ Ceph Storage โ Requirements - Environment, Undercloud, Network, and Overcloud โ Red Hat Storage - Ceph
- 3. Introduction to Red Hat OpenStack Platform
- 4. Introduction to Red Hat OpenStack Platform director
- 5. Undercloud โ Environment Planning โ Bare Metal System Control โ Orchestration โ Command Line Tools and Web UI
- 6. Overcloud โ Controller โ Provides administrative, networking, and HA for OpenStack โ Has OpenStack services, MariaDB, and Open vSwitch โ Pacemaker and Galera for HA services โ Ceph Monitors โ Compute โ Nova service, KVM/QEMU, Ceilometer agent, and Open vSwitch โ Ceph Storage โ Each node contains the Ceph Object Storage Daemon(OSD) โ Block, Object, and File Storage โ Storage layer scales like the OpenStack infrastructure layer.
- 7. Requirements
- 9. Environment Requirement NOTE: โ Recommended to use bare metals for all the nodes. โ All overcloud bare metal require Intelligent Platform Management Interface (IPMI). Node Type Minimum Recommended Director 1 1 Compute 1 3 Controller 1 3 Ceph 3
- 10. Undercloud Requirement Minimum requirement CPU 8 core 64-bit x86 processor for Intel 64 or AMD64 CPU extensions Memory 16 GB of RAM Disk 40 GB (root disk) NICs 2 x 1 Gbps NICs. Recommended 10 Gbps for Provisioning Host OS RHEL 7.3 SELinux Enabled
- 11. Network Requirement - Undercloud Network Purpose Provisioning Network Provides DHCP and PXE boot functions External Network For remote connectivity
- 12. Network Requirement - Overcloud NIC configs Purpose Single NIC configuration One NIC for both Provisioning and other Overcloud network types Dual NIC configuration One NIC for Provisioning, and other for the other Overcloud network types Multiple NICs Each NIC uses a subnet of a different Overcloud network types NOTE: โ NIC bonding for High Availability โ Set all nodes to PXE boot off the Provisioning NIC, and disable PXE boot on the other NICs.
- 13. Overcloud Requirement - Compute Minimum requirement Recommended CPU 4 core 64-bit x86 processor for Intel 64 or AMD64 CPU extensions. AMD-V and Intel VT virtualization enabled Memory 6 GB of RAM Additional RAM depends on the VMs running. Disk 40 GB NICs 1 x Gbps NICs. Recommended 2 (or more) x 10 Gbps
- 14. Overcloud Requirement - Controller Minimum requirement Recommended CPU 64-bit x86 processor for Intel 64 or AMD64 CPU extensions. Memory 32 GB of RAM 3 GB per vCPU eg: 3 x 48 vCPUs = 144 GB Disk 40 GB or more NICs 2 x 1 Gbps NICs. Recommended 2 (or more) x 10 Gbps
- 15. Overcloud Requirement - Ceph Minimum requirement Recommended CPU 64-bit x86 processor for Intel 64 or AMD64 CPU extensions. Memory 1 GB per 1 TB of hard disk space Disk 3 or more disks NICs 1 x 1 Gbps NICs. 2 or more 10Gbps NICs

- 19. Red Hat Ceph Storage: Workloads and Use cases SMALL MEDIUM LARGE 250 TB+ 1 PB+ 2 PB+
- 20. Red Hat Ceph Storage: IOPS-OPTIMIZED SOLUTION CPU 10 cores per NVMe SSD, assuming a 2GHz CPU RAM 16GB baseline, plus 2 GB per OSD Networking 10 GbE per 12 OSD (each for client and cluster facing networks) OSD media High performance, high endurance enterprise NVMe SSDs OSDs Four per NVMe SSD Journal media High-performance, high endurance enterprise NVMe SSD, co-located with OSDs Controller Native PCIe bus
- 21. Red Hat Ceph Storage: THROUGHPUT-OPTIMIZED SOLUTION CPU 0.5 cores per HDD, assuming a 2GHz CPU RAM 16GB baseline, plus 2 GB per OSD Networking 10 GbE per 12 OSDs (each for client and cluster facing networks) OSD media 7,200 RPM enterprise HDDs OSDs One per HDD Journal media High-endurance, high-performance enterprise serial-attached SCSI (SAS) or NVMe SSDs OSD-to-journal ratio 4-5:1 for an SSD journal, or 12-18:1 for an NVMe journal Host Bus Adapter (HBA) Just a bunch of disks (JBODS)
- 22. Red Hat Ceph Storage: COST/CAPACITY-OPTIMIZED SOLUTION CPU 0.5 cores per HDD, assuming a 2GHz CPU RAM 16GB baseline, plus 2 GB per OSD Networking 10 GbE per 12 OSDs (each for client and cluster facing networks) OSD media 7,200 RPM enterprise HDDs OSDs One per HDD Journal media Co-located on HDD Host Bus Adapter (HBA) Just a bunch of disks (JBODS)
