Agenda
 What is Object Storage
 StorageGRID Webscale Introduction
 Technical Overview
 Key Concepts
 Data flow

Object storage growth driven by macro trends…
Unstructured data continues
to grow
•New sources of unstructured data growth
media, mobile and applications
•Data continues to be retained for long
periods (archival, compliance etc)
Unstructured data profile is
changing
•Simultaneous access to the same data is
rarely required
•Most data accessed a few times initially
and then rarely accessed
Data access is changing
•Geographically dispersed access
•Applications accessing data – don’t care
about POSIX semantics, file locking
Highly cost sensitive petabyte
scale repositories
•Driving tradeoffs between $/GB, latency,
throughput, and data protection
Storage being managed in a
cloud ecosystem
•Unified management & orchestration
•Growth in cloud hosted applications that
leverage object storage

Introducing StorageGRID Webscale
 A new variant of StorageGRID
 Target object store (cloud, archive, media) use cases at massive scale
 New Features
 Protocols – native support for S3 API
 Scalability – 100 billion objects, 70 PB
 Simplicity – modular scalable resilient architecture, simplified deployment
 Proven track record for reliability and innovation

Block File Object
What is Object Storage?
Different ways to address data
Specific location on
disks / memory
Tracks
Sectors
Specific folder in fixed
logical order
File path
File name
Date
Flexible
container size
Data and Metadata
Unique ID

 Global namespace
 Explosive growth
 Respond to
compliance and
retention
requirements
 Cost effectively meet
SLAs with intelligent
data placement
 Access from
anywhere
 Control access,
security, and data
integrity

Metadata

 Scale beyond traditional
application metadata to enable
new capabilities
 Flexibility:
 Metadata is application defined
 Up to 4096 fields can be created as
requirements change (CDMI)
 No lock-in to predefined schema
 ILM engine evaluates the
metadata and applies policies
 S3 metadata available to the policy
engine
Extensive metadata management
Metadata – Why it matters ?
 Metadata is distributed throughout
the grid
 Increased scalability and resiliency
 Faster retrieval and efficient ILM policy
evaluation

Extensive metadata management
Metadata Management
 Metadata Includes – Object size, User Metadata, Bucket Name, Account Id
 CDMI supports a large number of user metadata fields (up to 4096)
 Policy support
 Metadata can be used in polices (CDMI & S3)
 No pre-configuration required for metadata, immediately available for policy use

 Simple configuration of SLO based storage across multiple sites and
storage grades

Customer Defined Storage grades
Associating Storage
Nodes with Storage
Grades
Creating Storage Grades
 Customers can configure their own Storage Grades, and associate them
with specific nodes

Site configuration – Not just a site
 Customers can model network costs, creating powerful configurations
 Possible Examples
 Configure two sites to be treated as one,
 Specify which sites are connected by high b/w pipes & low b/w pipes,
 Prefer traffic to go in a particular direction

Dynamic Policy Engine – An Overview
Data management key concepts
 Manage policies not objects
 Evaluate objects based on metadata
such as:
 Custom user application metadata
 Method of ingest (S3 or CDMI)
 Size of object
 Last access time
 Apply ILM rules to set:
 Geography — Placement of an object
 Storage grade — Type of storage used to
store an object
 Replication — Number of copies stored
 Retention — Set time during which an object
cannot be purged

Policy Management
ILM
Policy
When
If..
then..
• At Ingest
• Objects at rest (already ingested)
• After a read (enabling caching)
• Metadata matches specific criteria
• Move/Copy to one or more Storage Pools

ILM Rule – Specify the Conditions
When
If..
 Customers designate when a rule will be applied and what conditions
must be met to trigger the action for placement and retention.

ILM Rule – Defining data placement and retention
then..
 Simple configuration of complex placement rules, that are graphically displayed
for easy understanding

Combine ILM rules
 Highly complex business logic can be implemented by combining
multiple rules into a policy

ILM Policy Example
Application
writes to
grid via S3
Metadata
is
evaluated
DC1 DC2 DC3
 Store objects with S3 metadata “Bucket Name = ClientX” on ingest at
DC1 on SSD and DC2 on SATA for 90 days
 After 90 days store on DC1 on SATA and DC3 on Tape
1 x copy
DC1SSD
1 x copy
DC2SATA
90 Days
later….
1 x copy
DC1SATA
1 x copy
DC3Tape
Bucket
Name =
ClientX

ILM Policy Example
DC1 DC2 DC3
 What if requirements change?
 A new Data Center is brought on line and now we must store a copy at
DC4
 We can edit the policy – and apply not just to new data, but re-evaluate
existing data and create new replicas as needed
 Without impact to the performance of the grid
DC4

 Create ILM Rules to set
customized service levels
 GOLD = 2 x copies on SSD, 1 x copy on
SATA
 SILVER = 1 x copy on SAS, 2 x SATA
 BRONZE = 1 x copy on SATA, 1 x copy
on tape
Set custom service levels via metadata
SLA Example
{"sla":"gold"}

Built-in Object Integrity Verification and Self Healing
Durability at the object level
 Digital fingerprint is calculated per
object upon ingest
 Interlocking layers of object-wide
and sub-object level integrity
protection
 Object hash value
 Content hash value
 CRC checksum
 HMAC message authentication digest
ID: 41E85A1D

Fingerprint

Built-in Object Integrity Verification and Self Healing
Durability at the object level
 Continuous verification: on ingest,
retrieval, replication, migration and
at rest
 Object failing integrity test is
automatically replaced with
another copy

 Real time audit feed can be
used to create custom
reports
 Audit logs created in open
format allows the use of
partner products such as
Splunk
 Comprehensive audit feed
for:
 Chargeback and billing
 Search integration
 Custom reporting
 Security diagnostics
 Compliance events
 Validate performance for SLAs
