What is really important?

Who needs 1 million IOPS?

Who needs low latency?

3

Low latency yields

5x – 10x application acceleration can lead to

50% - 90% reduction in disk storage

no over-provisioning of disks to increase

performance

30% - 80% reduction in cores/servers

dramatic reduction in IO wait states of servers

30% - 70% reduction in HW based software licences

less processor cores, servers, storage capacity

60% - 90% reduction in power, cooling & floor

less racks of disks and servers

Flash Storage Approaches

Booster

Put an SSD card

in the application

server as read

cache

Pure flash

Use a specialized

all-flash storage

system

Traditional

Flash your

general purpose

storage system

5

Booster: Use a SSD Card in the Server

How does

it work

A PCIe Card with SSDs is built into a server acting as (read) cache

Additional software is managing the data caching

What to

consider

Works best with read applications where the data tends to be static

or non changing

Key is the software, check for which scenarios optimizations have

been made

Limitations Complex overall stack needing high expertise in implementation,

tuning and maintenance

Not easy to share between servers / applications – point solution

6

Pure Flash: All-Flash-Array (AFA)

What to

consider

Understand the root cause for performance issue in order to decide

whether all-flash arrays pay off (disk latency, bandwith !)

Although price is high there are many induced savings regarding

space, tuning efforts, power consumption, software licensing…

How does

it work

Purpose-built storage system for dedicated SSD usage

Has specific algorithms for wear leveling, RAID….

Can achieve a million IOPS

Limitations Budget

Capacity

Lack of features

7

Use Flash in General Purpose Storage

How does it

work Controller cache memory and SSDs accelerate performance

Software for storage tiering balances speed, capacity and costs

What to

consider Look for storage systems with high DRAM cache in the controller

Ask how much of the controller cache is used by system software

Check the granularity of the auto-tiering software

Check system architecture (buses, interconnects…)

Limitations General purpose systems are designed for hard disks and cannot

exploit fully SSD technology

Tiering software needs expert skills for efficient use

Not all traditional SANs are created equal

• IBM dedicated all flash is 19% slower even thou it is built for speed

• Huawei is 19% slower although SLC has half the latency

• HP is 36% slower and it is a 4 controller system using ASICS

• Netapp is 48% slower

• DELL is 760% slower (yes that is not a typo it is more then 7 times

slower)

Where are all the dedicated flash arrays?

ETERNUS is the fastest storage faster than dedicated flash

appliances

The Importance of the Operating system

Fujitsu has been developing and building storage for Mainframes for more

than 40 years.

Mainframe needs a responsive operating system that can handle heavy load.

Included no license needed

• Parity checksums with protection from Datarot (Data block guard, Drive Patrol)

• Encryption

• Snapshots

• Thin provisioning

• Quality of Services

• Extreme Cache

Licensed features

• Replication

• AST

• Automated QoS

• Storage Cluster

Checks the data on drives periodically in

the background (Read check)

If an error is detected, the data is recreated

from a drive in the RAID group

The recreated data is written to another

block on the same drive.

Errors on rarely accessed drives can be

detected as well

System and software

- No hidden costs, no bad surprises

Which licensing model do

you prefer?

Problem Bad surprises due to complex licensing model

Hard to predict growth rate

Even harder to predict licensing costs for upgrades

What we

deliver

Transparent and simple licensing model:

No capacity licensing

Only controller based licensing

We have no hidden costs ie mandatory cache upgrades etc

Start small don’t buy more capacity then you need.

Grow without fear of hidden cost, at a predictable price.

Why buy a dedicated Flash appliance?

• If you don’t want speed

• If you want a silo

• If you don’t want Enterprise features

• If you want to gamble on the survival of a upstart
