Scaleio Overview

ScaleIO Overview

(selected slides) Problem: Traditional Storage Arrays The old way

Deployment Management Refresh • Takes up to months to procure, • Siloes of unused storage • Need forklift upgrades every deploy and provision storage 3-5 years • Multiple arrays to manage • Overprovisioning • Large data migrations • Performance hotspots • High CAPEX

Traditional

SDS

Time

Deployment Management Refresh • Deploy in minutes! • “Abstract, Pool, Automate” - for • Rolling server upgrades Storage! • Start small, no • No large data migrations. overprovisioning • Data center scale, no silos Ever!

• Standard x86 servers and • HCI or traditional SAN • Superior TCO Ethernet

ScaleIO Data Client (SDC) Operating Systems • Manages connection to SDC • Microsoft Windows ScaleIO’s pool of storage • Linux ScaleIO Data Server (SDS) Deployed on… Hypervisors • Consumes local storage and SDS presents it to SDCs • VMware ESX • HyperV • Xen MDM Metadata Manager (MDM) • Coordinates and monitors storage Platforms • OpenStack • Mesos • Docker

And more…

Deployment and management components

• ScaleIO Gateway • Performs installation and configuration checks; acts as an endpoint for API calls and passes them to MDM

• ScaleIO Lightweight Installation Agent • Receives packages from gateway, installs them on its local host

• ScaleIO Graphical User Interface (GUI)

• ScaleIO Command Line Interface (CLI)

• All of these components do coexist along with SDS, SDC, MDM

Orchestration and deployment

• ScaleIO Advanced Management Services (AMS) • Extended interface for ScaleIO GUI • Manages and installs ScaleIO; must exist outside of ScaleIO system
