Traditional Approach

STORAGE

• The programming that controls the storage is decoupled from the physical hardware

• Consists of the Storage Tier Only

• Emphasizes storage services such as deduplication or replication, instead of storage hardware

• A shared pool that runs on commodity hardware

• Utilizes Policy Based Management

• Often referred to as Storage Virtualization and is part of a bigger industry trend of Software Defined Datacenter

Definition: What is Software Defined Storage (SdS)

Software Defined Storage

Local Physical Storage

Hosts

Storage Software can run on bare metal or as a VM on a hypervisor host

• New Converged Infrastructure offering utilizing Software Defined Storage

• Tight integration of x86 servers for compute and storage, networking and virtualization in all-in-one appliance. Packaging

• Integration of hypervisors and physical infrastructure

• Simple Scale one unit/appliance at a time

• Simple deployment measured in hours

• Centralized management, intuitive UI

• Storage presentation via a distributed filesystem or object store

Customer Criteria Converged HyperConverged

Compute, Storage, Network, Server Virtualization in one Flexible, allows choosing from Multiple Vendors

Rigid, single vendor offers or limited choices

Scalability Flexible, can scale up and out as needed

Has Limitations

Common Management Software Increasingly offered as an option

Built in by default

Packaged as a Single Unit Possible through SI Offered by default

Pre-Sized and Pre-configured Possible through SI Offered by default

Time to Deployment Days and weeks Hours

Pricing Perceived as high Perceived as low

Performance, Quality, and Uptime High – Designed and validated for high quality and availability at various scales and speeds

Low – Tests fail at higher scales and speeds

VM

Hypervisor Datastore

Storage Software

• Min of 2-3 nodes in a cluster providing storage

• Hardware to be similar with equivalent drive technology

• Scale 8 - hundreds of nodes (most support up to 64)

• Disks: Locally attached diskso Hybrid: spinning disks and flash deviceso All-Flash: Flash devices only

• Networko 1GB Ethernet ORo 10GB Ethernet (preferred)

• “Witness” node acts as tie-breaker during availability decisions

Storage Network

Data Tiering• All data ingested goes through SSD caching tier• SSD caching for read and write

• Allocation varies by vendor• Writes are committed replicated and

acknowledged at the SSD cache tier• Data is moved from SSD cache to spinning drives

• Time spent in cache is vendor specific• Performance is impacted when SSD tier is

flooded with heavy IO• Cache misses

• Some vendors also use Memory Caching• Moving data closer to the processor• More performance

VM

Write

Typical best practice is to have a 10:1 ratio of HDD to SSD capacity

• Data is protected by Replication or Erasure Coding• Most SdS/HCI stacks use replication but more are switching

• Replication factor min of 2• Cost is 50% of disk capacity• Every block is written to min of 2 different nodes in the cluster• Can survive a single node/device failure

• Higher device protection requires more replication• RF3 reduces RAW disk capacity to 33%• Requires min 5 nodes

HCI Data High Availability

Write IO

Network Considerations• Many solutions require Multicast and IPv6 for node

discovery and scale out• Multicast used for exchanging metadata and storage

network heartbeats• Redundant 10Gb networking required for storage data • Management/VM networking separate from storage

network• Density solutions will require a large number of 10Gb

uplink ports• Direct access to switches for low latency storage
