This session will cover private and public cloud storage options, including flash, disk and tape, to address the different types of cloud storage requirements. It will also explain the use of Active File Management for local space management and global access to files, and support for file-and-sync.

• Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual
throughput or performance that any user will experience will vary depending upon many factors, including considerations such as the
amount of multiprogramming in the user’s job stream, the I/O configuration, the storage configuration, and the workload processed.
Therefore, no assurance can be given that an individual user will achieve results similar to those stated here.

3. Cloud Storage Taxonomy
Reference Storage
• Archives
• Images/Video
• WORM/NENR
Ephemeral Storage
• Typically boot volumes,
page files and temporary data
• Goes away when VM
is shutdown
Persistent Storage
• Persists across
VM reboots
• Can be shared
between VMs
• Transactional
• High Performance
Storage as the Storage CloudStorage for Compute Cloud
Hosted Storage
• File and Object access
• File Sync & Share
• Backup/Disaster Recovery

Object
Archival
Online
Ephemeral
Persistent
• Block storage offerings are differentiated by speed/throughput (as measured in
IOPS) and segmented by lifecycle of the disk. Device location does not matter.
• Ephemeral storage is tied to the lifecycle of a single VM (i.e. it is provisioned
when the VM is provisioned and destroyed when the VM is destroyed)
• Persistent storage has a lifecycle independent of any single VM and can be
provisioned/destroyed at any time and attached/detached to many VMs during it’s life
• File-based offerings are uncommon among providers, especially among those
targeting cloud native applications
• Primarily targeted at cloud enabled workloads
• Usage is being replaced in new application development with online object
storage
• Object storage offerings are differentiated by the durability of the data (i.e. odds of
irrecoverable loss) and segmented by the availability of the data (i.e. time
required to retrieve)
• An object in online storage is immediately accessible
• An object in archival storage may require minutes to hours to be accessible

Information Dispersal
Algorithm (IDA)
Erasure coding is used to
transform encrypted pieces of
data into a customizable
number of slices (7 pieces into
12 slices, in this example)
Highly Scalable and Reliable
Only a subset of disks needed
to retrieve data (any 7 disks out
of 12, in this example)

With erasure coding “k” pieces are turned into “n” slices:
Reads can be performed using any k of the n slices
• This example is a “7 of 12” Information Dispersal Algorithm (IDA) means only 7
slices are needed to reconstruct the original object
With this IDA, a read can
still be executed with any
five storage nodes being
unavailable out of 12.
With 3 sites, even an
entire site outage (plus
one additional storage
node outage) can be
tolerated.
