Abstract
2
This session will cover the basic concepts
of NAS File and Object Storage, and
general overview of IBM’s various NAS
solutions.
The presenter will then show how to use
the "File and Object Storage Design
Engine“ studio, a pre-sales sizing tool for
IBM Spectrum NAS, IBM Spectrum Scale,
and IBM Cloud Object Storage.
Example screenshots for IBM Spectrum
NAS will be used to explain the steps
involved.

basic concepts
• IBM NAS solutions
• File and Object Storage (FOS)

File and Object Storage Differences
5
File-based Network Attached Storage (NAS)
– Can be used for Active or Inactive Data: Databases, Logs and Traces,
Virtual Machines and VDI, Documents and other unstructured data
– Most NAS data is “static and stable”, not updated frequently if at all
– NAS Protocols: SMB (formerly CIFS), and NFS
Object-based Storage
– For Static and Stable data: Documents, Archives, Video, Audio,
Photos, Medical Images, Seismic readings, Research results
– Object Protocols: HTTP, Amazon S3, and OpenStack Swift
– NAS gateways can offer SMB, NFS protocols to Object storage

Terminology – Nodes, Clusters, and Sites
6
Nodes can be:
– Storage rich servers: commodity
servers with Flash and Disk inside
– Paired up: Dual-Controller,
Twin-tailed Flash and Disk media
Cluster-to-Cluster Replication:
– Synchronous or Asynchronous
Clusters are a combination of nodes to
represent the file or object system
– Single site, or across multiple sites

RAID versus Erasure Coding
7
Tolerate 1 drive failure Tolerate 2 drive failures Tolerate “M” failures
RAID-1 / RAID-10
K pieces 2 x K slices

Data Footprint Reduction – Compression and Deduplication
9
Lossless Compression
– Used with databases, emails,
spreadsheets, office documents,
source code
– Can be done in-line or
post-process after data is stored
– Lempel-Ziv (LZW, LZ4)
Exactly
the same
Compress
Decompress
returns data
back to its
original contents
Compress
Data Deduplication
– Store only one unique portions of the
data
– Redundant data replaced with pointers
– Used with Backups, VDI
– Performed by application or gateway
before it is stored on IBM solution

Immutability, WORM, NENR and Compliance
10
Some data must be tamper-proof, no changes allowed
ever, and cannot be deleted for specific period of time
Various Terms have been used:
• Write Once Read Many (WORM) for tape and optical
• Fixed-Content or Content-Addressable for disk
• Immutable or Compliance-enabled for file systems,
object storage, and Cloud
Non-erasable, Non-rewriteable (NENR) adopted as
phrase to cover all of the above storage types
“electronic storage must preserve the records
exclusively in a non-erasable, non-rewriteable,
format”
-- United States SEC 17a-4

Introducing File and Object Storage (FOS) Design Engine Studio
26
Client needs storage
Carline needs a storage
solution for office
documents
(Presentations,
Spreadsheets,
Contracts).
She manages a group of
48 Windows users and
12 Linux Servers, and
needs perhaps 200 TB.
Sam arranges a meeting
with the broader team to
discuss a NAS solution.
Caroline,
Client Lead
Sam,
Storage Rep
FOS Design Engine is
not a “First Meeting”
tool
Ned indicates they have
10Gb Ethernet already
deployed, there is only
one site for this solution
to be installed, and they
do not plan to setup
Disaster Recovery or
other sites for another 2-
3 years.
Tina uses FOS Design
Engine studio to capture
details, requirements,
and formulate workable
design.

FOS Design Engine – Get Started with the Dashboard

FOS Design Engine – Get Started with the Dashboard
The Dashboard will identify the most appropriate IBM solutions to fit the
requirements
Each IBM solution has a different template, different questions to fill out

FOS Design Engine – Fill in the Template
30
Fill in the Template
– Answers to these basic
questions will be used to
generate an initial design

FOS Design Engine – Ensure Client Success
Client Skills Assessment
– For more complicated
deployments, address skill
gaps with Lab Services and
Training

FOS Design Engine – Adjust Design Options
32
Initial Design
– Yellow (Warning) and Red
(Error) means it does not
meet requirements
Final Design
– Adjust number of
nodes, drives or size
– Green indicates that it
meets requirements

FOS Design Engine – Generate Report (pdf file)
