Q&A 4


I/O Logjam & Advent of SSDs


Customer Need - Performance

• Lots of clients quickly strain shared storage infrastructure

• Concurrent & blended IOs aggravate the I/O bottleneck

• 8% of all data requires low latency, high IOPS

• NextGen Applications being designed for low latency

• Tier1 Application needs increasing

• CPU vs. HDD gap & ‘I/O blender’ limits virtualization

• CPU = 175x vs. HDD IO = 1.3x

• IOs reach the spindles in a random fashion

• Gets worse with higher # of apps or VMs per LUN

• SSDs $30/GB->$2/GB (08-12)

• TCO much lower than HDD

• $ / IOPS better for SSDs

• Better “write endurance” & lower write perf issues

SmartIO for Hyper-V


SYMANTEC VISION 2013 17 IA B08: Blow Up I/O Logjams in Virtualized Environments w/o Explosives

Why SmartIO for Hyper-V?

• IOs reach the spindles in a random fashion

• Disk seek times & rotational latencies slows down IO

• Throwing more spindles at the problem is cost prohibitive

• Gets worse with higher # of apps or VMs per LUN

IO Blender problem Advantages of SmartIO in Hyper-V

• Ability to handle OLPT IOs from multiple VMs in a Hyper-V Server

• Deliver same or better performance without the

need to buy expensive SAN hardware.

• Transparent : No Virtual Machine reconfiguration required to boost IO performance.


SmartIO in Hyper-V: Overview

Cache Area: – Stores cached IO on one or more SSD

devices.

– There is one “default” cache area.

– Cache area is created in the Hyper-V Parent Partition.

Volume Mapping: – SFW Volumes are created in the Hyper-V

Parent Partition.

– Multiple Volumes share a single Cache Area.

Virtual Machine Data (VHDs): – Data of each VM stored on one or more

SFW Volumes.

Indexing Engine

Policy Engine

Cached data on SSD

Cache IO Management: – Intercept all IOs

– Checks for a “hit or miss”

– Refers to the Policy to cache IO or not

Indexing Engine – Look-up IOs based on

Volume Id & offset inside the SSD.

Policy Engine – Tuneable policy engine

– Avoid caching certain data

– Sequential read detection

– Advanced Heuristics
