HPE Complete CohoData: технические характеристики и документация

The Coho DataStream architecture takes full advantage of the emerging technologies that are reshaping IT. Our architecture delivers on today's and future data demands, which demand a new approach to storage infrastructure - one that is flash-tuned, ultra high- performance, self-managing, and massively scalable. The Coho DataStream architecture uses the rack as its design paradigm, creating a new foundational software stack that is better equipped to run, manage, and optimize data center operations. It is the only solution that integrates Software Defined Network (SDN) and Software Defined Storage (SDS) on commodity hardware to empower customers to cost effectively transform their data centers into a source of competitive advantage.

Figure 1. Coho DataStream Architecture

Software-Defined Network (SDN)

• OpenFlow based Leaf/Spine architecture provides high performance scalable backplane
• SDN-integrated data path allows transparent scalability of a single IP address while preserving host and rack locality
• Storage-aware SDN controller and constraint-based engine provide topology-aware placement of data and connections 

Software-Defined Storage (SDS)

• Scale-out distributed file system with rich enterprise data services
• QoS/Multi-tenancy for performance and resource isolation
• Workload Profiling: Continuous, compact summary of working set over time simplifies application sizing, burst detection and informed tiering 

Automation and Orchestration

• RESTful APIs and Microsoft PowerShell modules offer programmable access to each component that can be connected into orchestration and automation platforms
• VMware VAAI, Site Recovery Manager (SRM) integration offers hardware accelerated cloning, snapshot and replication
• OpenStack Cinder APIs for storage management and virtual machine level granular performance monitoring through single management pane
• Google Kubernetes integration allows for orchestration and provisioning of containers directly on Coho DataStream nodes

Key Features and Benefits  

Simplified Management

Cloud-like ease of provisioning and management

• Self provisioning and healing with no manual intervention, no reconfiguration and no application changes
• Centralized management and workload profiling for application sizing and burst detection

Flexible and Efficient

Offering 'Always ON' infrastructure

• Flexibility of seamless change management to support newer technologies
• Non disruptive operations to eliminate planned and unplanned downtime without application disruption

Workload Consolidation

File, Block, Hadoop and Containers on the same platform with QoS

• Run virtualized and New IT workloads (Big Data analytics) on a single scalable platform with workload isolation at network and storage level
• Automated container orchestration directly on storage nodes with tenant isolation

Lowest TCO

Public cloud economics for private cloud

• Lower Capex by using commodity hardware and consolidating multiple workloads (NFS, iSCSI and HDFS)
• Lower Opex by simplifying and automating infrastructure deployment
