New Storage Tiers Are Rapidly Growing

7

• Flash: Enables New Storage Architectures

• Flash is 50x – 2,000x faster than HDD

– 110K/140K IOPs R/W from 360GB MLC PCIe card1

– Less than $0.10 per IOP

• Eliminates the need to stripe across 100s of HDDs

• Enables high performance server-side storage

• Cloud: Enables Cost-Effective Storage

• Highly scalable, pay-as-you-go

• Access through standard APIs

• Low cost for capacity

– $0.05 per GB per month2

• Forecasted to grow at 40% annually to 20183

• Software-defined storage

embedded in vSphere

• Runs on any standard x86 server

• Pools HDD/flash into a shared

datastore

• Managed through storage policy-

based management framework

• High performance through flash

acceleration

• Highly resilient - zero data loss in

the event of hardware failures

• Deeply integrated with the

VMware stack

Flash Based Devices

In Virtual SAN ALL read and write operations always go directly to the Flash tier.

Flash based devices serve two purposes in Virtual SAN

1. Non-volatile Write Buffer (30%)

– Writes are acknowledged when they enter prepare stage on SSD.

– Reduces latency for writes

2. Read Cache (70%)

– Cache hits reduces read latency

– Cache miss – retrieve data from HDD

Choice of hardware is the #1 performance differentiator between Virtual SAN configurations.

13

Magnetic Disks (HDD)

• SAS/NL-SAS/SATA HDDs supported

– 7200 RPM for capacity

– 10000 RPM for performance

– 15000 RPM for additional performance

• NL SAS will provide higher HDD controller queue depth at same drive rotational speed and similar price point

– NL SAS recommended if choosing between SATA and NL SAS

• Differentiate performance between clusters with SSD selection, and SSD:HDD ratio. Rule of thumb guideline is 10% of anticipated capacity usage

14

Storage Controllers

• SAS/SATA Storage Controllers

– Pass-through or “RAID0” mode supported

• Performance using RAID0 mode is controller dependent

– Check with your vendor for SSD performance behind a RAID-controller

• Storage Controller Queue Depth matters

– Higher storage controller queue depth will increase performance

• Validate number of drives supported for each controller

15

Network

• 1Gb / 10Gb supported

– 10Gb shared with NIOC for QoS will support most environments

– If 1GB then recommend dedicated links for Virtual SAN

• Jumbo Frames will provide nominal performance increase

– Enable for greenfield deployments

• Virtual SAN supports both VSS & VDS

– NIOC requires VDS

– Nexus 1000v – Should work but hasn't been fully tested

• Network bandwidth performance has more impact on host evacuation, rebuild times than on workload performance

Virtual SAN Is Highly Resilient Against Any Hardware Failure Virtual SAN is Designed to Ensure Data is Never Lost in Case of Failures

Failure handling philosophy

Traditional SANs

– Physical drive needs to be replaced to get back to full redundancy

– Hot-spare disks are set aside to take role of failed disks immediately

– In both cases: 1:1 replacement of disk

Virtual SAN

– Entire cluster is a “hot-spare”, we always want to get back to full redundancy

– When a disk fails, many small components (stripes or mirrors of objects) fail

– New copies of these components can be spread around the cluster for balancing

– Replacement of the physical disk just adds back resources
