New approach to the design and
deployment of storage
Piotr Biskupski – IBM STG Poland
IBM Forum 2012 – Estonia
Tallinn, October 9, 2012
To realize the promise of a Smarter Planet, enterprises
must address the IT challenges that have emerged.
31.9 million servers worldwide
Internet connected devices—
22B in 2020 (24.9% CAGR)
Last 10 years servers up 2X and
virtual machines up 42% CAGR
Since 2000 security
vulnerabilities grew eightfold
The volume of digital content, up
48% from 2011, is expected to
reach 2.7 ZB (1ZB = 1 billion
terabytes) in 2012 and 8ZB by
2015.
Data centers have doubled
energy use in past 5 years
And respond to demands for new services…
Real-time analytics workloads
growing 13% CAGR with
related server spend growing
3x average
2
Collaborative software
workloads growing 10%
CAGR
…while dealing
with constraints
like a flat budget.

Thin-provisioning
 Traditional (“fully allocated”) virtual disks use physical disk capacity for the entire capacity of a virtual disk even if it
is not used
 With thin-provisioning, Storwize V70000 allocates and uses physical disk capacity when data is written
Dynamic
growth
Without thin provisioning, pre-allocated space
is reserved whether the application uses it or
not
With thin provisioning, applications can grow
dynamically, but only consume space they are
actually using
 Available at no additional charge with base virtualization license
 Support all hosts supported with traditional volumes and all advanced features (EasyTier, FlashCopy, etc.)
 Reclaiming Unused Disk Space
– When using Volume Mirroring to copy from a fully-allocated volume to a thin-provisioned volume, Storwize
V7000 will not copy blocks that are all zeroes
– When processing a write request, Storwize V7000 detects if all zeroes are being written and does not allocate
disk space for such requests in the thin-provisioned volumes
● Helps avoid space utilization concerns when formatting Volumes
 Done at Grain Level (32/64/128/256KiB) If grain contains all zeros don’t write
Real-Time Compression
• A compressed Volume is a third type of volume
– Regular (fully allocated)
– Thin Provisioned (Space Efficient)
– Compressed
• A compressed volume is “a kind of” Thin Provisioning
– Compression supports all Thin Provisioning features (e.g. autoexpand)
– Only uses physical storage to store the compressed version of the volume
– Can be on back-end virtualized storage
Storwize V7000
R

– Supported with CLI and GUI
• GUI also has a preset for compressed volumes
• Performance monitoring tab support for Compression CPU resource usage
• Compression operates at a volume copy level
– Maximum of 200 compressed Volume copies per IO group
Copy 0
• Specified at creation of the volume copy
– No conversion in place, but a volume can be converted via Volume Mirroring1
• Compressed volumes can be source and target of Remote Copy relationship or FlashCopy mapping
– Data between copies is uncompressed

 Orion (Oracle I/O Calibration Tool) is a standalone tool for calibrating the I/O performance for storage systems that are intended to
be used for Oracle databases. The calibration results are useful for understanding the performance capabilities of a storage system, either
to uncover issues that would impact the performance of an Oracle database or to size a new database installation

What is Easy Tier?
–
A function that dynamically re- distributes active data across multiple tiers of storage class based on workload characteristics
–
The goal being to reduce response time
–
Users have automatic and semi-automatic extent based placement and

Optimized performance and throughput
Why it matters?
Solid State Storage has orders of magnitude better throughput and response time with random reads
Full volume allocation to SSD only benefits a small number of volumes or portions of volumes, and use cases
Allowing dynamic movement of the hottest extents to be transferred to the highest performance storage enables a small
number of SSD to benefit the entire infrastructure
Works with Thin-provisioned Volumes

Modular Scalability
• Start with a single control enclosure (a pair of controllers)
– And add up to 9 expansion enclosures to scale-in
• Mix 2.5” & 3.5” drive enclosures
• Mix drive type and drive size in an enclosure
• Add control enclosures independently of expansion enclosures
– Build a cluster (a Grid) of controller pairs to scale-out
– Add expansion enclosures as required for capacity and performance

Overview of the I/O Stack
SCSI target
• SCSI Target – looks like a disk system and presents Volumes to Hosts (HBA
driver layer)
• Remote Copy – replicates data to second site for disaster recovery
• Cache – mirrors writes between nodes in I/O Group
• FlashCopy creates point-in-time copies
• Volume Mirroring – provides pointers to two copies of data for high
availability
• Thin-provisioned Volume – consumes disk space only when data written
–Random Access Compression EngineTM sits parallel to Thin-Provisioning
 acts in coordination
• RACE is running in a controlled binary executable Comperssion
• Virtualization – Volume  MDisk mappings, non-disruptive data
migration
• RAID – Internal storage Array  1 array = 1 Mdisk migration
• SCSI Initiator – talks to disk backend just like a host accessing LUNs

VMware Site Recovery Manager
Site Recovery Manager leverages
VMware Infrastructure to transform disaster recovery
• What it is:
– Site Recovery Manager is a VMware
product for disaster recovery
• What it does:
– Simplifies and automates
disaster recovery processes
• Discovery of replicated storage
• Non-disruptive failover test using a writable
copy of replicated data
• Emergency and planned failover
• Reverse replication after failover as part of failback
• Restore replication after failover as part of a production test
• Site Recovery Manager works with VMware Infrastructure to enable faster, more
reliable, affordable disaster recovery
VMware vStorage API for Array Integration
VAAI support
• Integration with vStorage API’s to improve performance
– Full copy (and Block zeroing which was delivered in 6.1.0) offload work from production virtual
servers to storage which improves application performance
– Hardware-assisted locking enables a finer grained level of locking on VMFS metadata which is more
efficient and also scales better in larger VMware clusters
• Example tasks that can benefit from improved performance :
– VM creation/cloning/snapshots/deletion
– vMotion and storage vMotion
– Extending a VMFS Volume
– Extending the size of a VMDK file

IBM Smarter Storage for Smarter Computing
Efficient by design
• With Smarter Storage, essential storage technologies are built in and tightly
integrated. Efficiency is effortless – requiring no manual intervention. Management
is intuitive and easy – improving the efficiency of your most important asset, your
people.
Self-optimizing
• Smarter Storage analyzes data access patterns, adapts and improves performance.
Sophisticated internal analytics automatically place data on the appropriate storage
tier.
Cloud agile
• Smarter Storage fully participates in highly virtualized cloud environments. Both
IBM and non-IBM storage are managed as one virtual storage pool. Existing storage
systems inherit IBM's latest, most advanced capabilities. Data is automatically
synchronized between facilities. Files flow to users wherever they are.
