VMware Virtual SAN

Why Virtual SAN?

• Server-side economics• No large upfront

investments• Grow-as-you-go• Easy to operate with

powerful automation• No specialized skillset

• Embedded in vSphere kernel

• Flash-accelerated• Up to 4M IOPs from 64

nodes• Granular and linear

scaling

• Two click Install

• Policy-driven • Self-tuning

• Integrated with VMware stack

Lower TCORadically simple High performance

• Minimum of 3 hosts in a cluster configuration* ROBO is 2 hosts with Master Cluster

• All 3 host MUST!!! contribute storage• Recommended that hosts are configured

with similar hardware• Hosts: Scales up to 64• Disks: Locally attached disks

– Hybrid: Magnetic disks and flash devices– All-Flash: Flash devices only

• Network– 1GB Ethernet OR– 10GB Ethernet (preferred)

• “Witness” component (only metadata) acts as tie-breaker during availability decisions

Virtual SAN Use Cases

• Handle peak performance requirements (boot, login, read/write storms)

• Granularly scale from POC to production without huge upfront investments

• Supports high VDI density

Disaster Recovery

Virtual Desktop (VDI) Tier 1-2 Production Staging &

Test/Dev

Site A Site B

• Simple to deploy and manage for any vSphere admin through integration with VMware stack

• High performance and consolidation ratios

• VM level SLA management via policy

• Integrated with vSphere Replication and VMware SRM

• Reduces cost of storage

• Minimizes data center footprint

• Rapid storage provisioning and complete automation

• Reduces cost of storage for non-mission critical workloads

• Enables Cloud Architect to easily provision storage

I/O Activity Accumulates

Heat at Sub-File Granularity

Automated movement of hot/cold data between SSD and HDD

• Use the best capabilities of HDD for capacity, and SSD for performance in a single volume

• Provides exceptional IOPs/$ and $/TB

Admins can override automatic placement, and pin files to a tier

• Can be used, for example, to offer different performance levels to tenants

Write-back cache absorbs write bursts• Helps smooth workloads which are bursty, reducing seeks on HDDs• WBC uses SSD capacity

Capabilities Overview (cont)

• Choose SSDs, HDDs, enclosures, and servers• Resiliency Needs

• How many drive failures must the deployment be resilient against?• What level of resiliency to enclosure failure is necessary?

• Capacity Needs• Overhead necessary for resiliency• Using Deduplication?

• Performance Needs• Workload dependent• Can start to characterize based on raw IOPS and Throughput
