Network Architecture for Ceph Storage

 As data continues to grow exponentially storing today’s data volumes in an efficient way is a challenge. Traditional storage solutions neither scale-out nor make it feasible from Capex and Opex perspective, to deploy Peta-Byte or Exa-Byte data stores. OpenStack Ceph Storage is a novel approach to manage present day data volumes and provide users with reasonable access time at a manageable cost.

 

 Ceph is a massively scalable, open source, software-defined storage solution, which uniquely provides object, block and file system services with a single, unified Ceph Storage Cluster.

 Ceph uniquely delivers object, block, and file storage in one unified system. Ceph is highly reliable, easy to manage, and open-source. The power of Ceph can transform your company’s IT infrastructure and your ability to manage vast amounts of data. Ceph delivers extraordinary scalability –thousands of clients accessing petabytes or even Exa-bytes of data. A Ceph Node leverages commodity hardware and intelligent daemons, and a Ceph Storage Cluster accommodates large numbers of nodes, which communicate with each other to replicate and redistribute data dynamically. A Ceph Monitor can also be placed into a cluster of Ceph monitors to oversee the Ceph nodes in the Ceph Storage Cluster, thereby ensuring high availability.

 

 This architecture is a cost effective solution based on HPE Synergy Platform which can scale out to meet multi Peta Byte scale.  

HPE Synergy Advantage for Software Defined Storage

Cloud Platforms requires massively scalable, programmable storage platform that supports cloud infrastructure, media repositories, backup and restore systems, and data lakes. HPE Syergy is an ideal plaform for such demands that provide a cost effective SDS storage solution; and introduce cost-effective scalability that modern workloads require.

HPE Synergy 12000 Frame forms an excellent platform for high performance SDS storage that scales to meet business demand. The Frame is the base infrastructure that pools resources of compute, storage, fabric, cooling, power and scalability. IT can manage, assemble and scale resources on demand by using the Synergy Frame with an embedded management solution combining the Synergy Composer and Frame Link Modules.

 The Synergy Frame is designed to meet today’s needs and future needs with continuing enhancements to compute and fabric bandwidths, including photonics-ready capabilities. Enhancements to the HPE Synergy 12000 Frame include several new capabilities:

 • Support for HPE Synergy 480 and 660 Gen10 Compute Modules.

 • Additional 2650W hot plug power supply options: HVDC, 277VAC, and -48VDC.

 • Product version to comply with the Trade Agreements Act (TAA).

 HPE Synergy is a single infrastructure of physical and virtual pools of compute, storage, and fabric resources, and a single management interface that allows IT to instantly assemble and re-assemble resources in any configuration. As the foundation for new and traditional styles of business infrastructure, HPE Synergy eliminates hardware and operational complexity so IT can deliver infrastructure to applications faster and with greater precision and flexibility.

D3940 Storage Module provides a fluid pool of storage resources for the Composable Infrastructure. Additional capacity for compute modules is easily provisioned and intelligently managed with integrated data services for availability and protection. The 40 SFF drive bays per storage module can be populated with 12 G SAS or 6 G SATA drives. 

Expand up to 4 storage modules in a single Synergy 12000 Frame for a total of 200 drives. Any drive bay can be zoned to any compute module for efficient use of capacity without fixed ratios. 

A second HPE Synergy D3940 I/O Adapter provides a redundant path to disks inside the storage module for high data availability. 

The HPE Synergy D3940 Storage Module and HPE Synergy 12Gb SAS Connection Module are performance optimized in a non-blocking 12 Gb/s SAS fabric.
