Introduction¶
Intended Audience¶
This document is intended for Storage Administrators of the Zadara Storage Cloud who are responsible for managing the cloud and providing Enterprise Storage-as-a-Service via the Zadara Storage VPSA service.
Zadara Storage Command Center¶
Overview¶
Zadara Storage Cloud was architectured from the ground up to build the first “Enterprise-Storage-as-a-Service Data Storage System for the Cloud” with the following key targets:
Enterprise quality, resilient, highly available, consistent performance storage for the most demanding data center application workloads
Consumed as a Service - flexible, dynamic and billable
Scale out - grow to hundreds of Storage Nodes, thousands of drives and multi-Petabyte Storage
True Multi-tenancy - End-user controlled privacy and security. Separate workloads, resource allocation, and management per tenant, such that each tenant truly experiences “no noisy neighbors” secure storage.
Universal Storage - Supports all data services on one common infrastructure: Block, File, Object
Zadara Command Center is a centralized point of management and monitoring for the Zadara Storage Cloud. Command Center enables Administrators to:
Extract detailed information regarding cloud elements such as : VPSA instances , storage Nodes , disk drives and software images
Define global cloud level polices that impact all underlying tenants
Monitor Cloud resources utilization and health from a single pane of glass
Maintain cloud infrastructure and control software images available for tenants
Perform management and maintenance operations on Virtual private storage array instances defined on the cloud
Manage cloud expansions (adding storage nodesdisk drives)
Perform cloud user management
Perform cloud level license key management

Terminology¶
Item |
Description |
|---|---|
SN |
Storage Node. Commodity server with large number of CPU cores (typically 16 or more ) and large RAM (typically 64GB or more), connected to 10Gb/40Gb data network with Intel/Mellanox SRIOV NICs & 1Gb management network |
VPSA |
Virtual Private Storage Array. A redundant and Highly available Software Defined Storage (SDS) that has all resources (CPU, memory, network, disks) provisioned entirely for itself thereby providing consistent QoS storage |
VPSA Object Storage |
Zadara Intelligent Object Store. Redundant, Durable, Highly Available virtual object store cluster that has resources (CPU, memory, network, disks) provisioned |
VC |
Virtual Controller. A Virtual Machine running Zadara Storage IO stack. Two VC’s are paired together in High-Availability configuration to form a VPSA. |
Provisioning Portal (eCommerce) |
The web application portal for the end-users to create VPSA’s/VPSA Object Storage and provisioning their resources (Drives, IO Engines, Flash Cache etc). Pricing and Billing are also managed via the Provisioning Portal |
Cloud Controller (CC) |
Set of software components that manages the storage cloud (like allocating resources for VPSA/VPSA Object Storage with intelligent scheduler, monitoring, and provisioning networking/storage for VPSA/VPSA Object Storage etc.) |
Command Center |
Web Application for the Cloud Administrator to monitor and maintain the Zadara Cloud (inventory management, maintenance operations etc) |
CCVM |
A system Virtual Machine within the Zadara Cloud which runs the Command Center and the provisioning portal |
FE Network/Data Network |
Front-End network. 10Gb/40Gb network through which Application Servers can connect to Zadara VPSA Storage for IO and Control |
BE Network |
Back-End network. 10Gb/40Gb network through which SNs and VPSA interconnect for data IOs |
Management Network |
Internal 1Gb network for management operations of VPSA, VPSA Object Storage & SN |
SRIOV |
Single Root IO Virtualization. A networking standard by which a physical adapter is logically provisioned for different VMs, bypassing the Hypervisor |
Application Server |
A server or a Virtual Machine in the Compute Cloud which consumes VPSA iSCSI Block Volume or NAS shares |
Tenant |
Each end-user that accesses Zadara Storage Cloud. NOTE: Each end-user could have multiple users/logins, but they all could belong to same tenant |
QoS |
Quality of Service - Defines Performance/Reliability characteristics of a service |
