What is Virtualization?

� Logical representation of resources not constrained by

physical limitations

�Create many virtual resources within single physical device

�Reach beyond the box – see and manage many virtual

resources as one

�Dynamically change and adjust across the infrastructure

IBM Virtualization Engine

A comprehensive platform to

help virtualize the infrastructure

Storage Virtualization is . . .

Technology that makes one set of resources

look and feel like another set of resources,

preferably with more desirable

characteristics…

A logical representation of resources not

constrained by physical limitations– Hides some of the complexity

– Adds or integrates new function with existing services

– Can be nested or applied to multiple layers of a system

Why Storage Virtualization?

� Not “just another way of helping manage SANs”

� Storage virtualization complements server virtualization

– Both technologies help increase flexibility and speed

responsiveness

� Storage management used to be manually intensive, time-

consuming and disruptive to the business

� Storage virtualization with SVC can help change that to

automatic, time-saving and non-disruptive to the business

� Radically changes the way you think about and work with

storage to make it fundamentally more flexible than just disk

boxes alone





Why is SVC Important?

Overall, SVC helps reduce storage cost

� Helps improve storage utilization

– Make better use of existing storage and control growth

� Designed to improve application availability

– Make changes to storage and move data without taking applications down

� Helps simplify management

– Greater efficiency and productivity for storage management staff

� Offers network-based replication

– Helps enable greater choice when buying storage

SVC Facts

� IBM has 40 years experience in virtualization technologies

� IBM has shipped over 9000 SVC engines running in more than 3100 SVC systems

� There are more than 130 customer references for SAN Volume

Controller

� SAN Volume Controller is a proven offering that has been delivering

benefits to customers for four years

� SAN Volume Controller demonstrates scalability with the fastest

Storage Performance Council benchmark results

� SAN Volume Controller can virtualize IBM and non-IBM storage (over

120 systems from IBM, EMC, HP, HDS, Sun, Dell, NetApp, Fujitsu, NEC,

Bull)

SVC Delivers Availability, Performance, and Scalability

� We designed and built SVC with

the resiliency of a storage controller

� SVC supports non-disruptive firmware

updates and hardware maintenance on

the disk arrays to further increase its

availability

� SVC is a proven offering, having been

delivering benefits to customers for four

years

It’s resilient

and highly available

It has the fastest benchmark of

any controller

It scales to manage

large environments

� SVC has the fastest SPC-1

benchmark EVER submitted

(155K IOPS)

� SVC has the fastest SPC-2

benchmark EVER submitted

(4.544 GBPS)

� Many references quote

significant performance

improvements

(up to 10X faster)

� SVC scales from very

small configurations

(1TB) to large

enterprises

(> 500TBs) and growing !

� New SVC engines deliver

dramatically better

throughput, supporting

larger and more I/O

intensive environments

Combine the capacity from multiple arrays into a single pool of storage

Apply common copy services across the storage pool

Manage the storage pool from a central point

Make changes to the storage without disrupting host applications

Flexible Storage Infrastructure with SVC

SVC 2145-8G4 Storage Engine

� New SVC engine based on IBM System x3550 server – Two dual-core Intel Xeon 5160 processors at 2.33GHz

– 8GB of cache

– Four 4Gbps FC ports

– SVC code improvements to use multi-core processor• Improvements also deliver potential benefits to customers with previous model SVC nodes

� Dramatically improved throughput compared with 8F4 engines

� Helps support larger, more I/O intensive storage configurations

� New engines may be intermixed in pairs with older engines in SVCclusters– Helps protect investments and offers enhanced growth capability

� Cluster nondisruptive upgrade capability may be used to replaceolder engines with new 8G4 engines

What’s New with SVC Version 4.2

� Dramatically improved throughput with new Model 8G4 engines

– Helps enable SVC to address larger and more I/O intensive environments

� Copy Services Enhancements including multi-target FlashCopy

– Help support greater flexibility by enabling multiple copies of source data

� Role-based authentication

– Designed to provide better control over access to managed storage resources

� Fast node reset, email and inventory reporting features

– Help improve reliability, availability and serviceability characteristics

� Redundant AC power

– Designed to increase reliability and ease of maintenance by supporting redundant power inputs

using dual-input power distribution unit (PDU)

� Expanded server and storage environment support

– Extends range of environments supported by SVC

Breakthrough Performance with SVC 4.2

� SPC-1 benchmark: Simulates I/O characteristics of OLTP workloads

– SVC 4.2 delivers 75% better throughput than SVC 4.1: 272,500 SPC-1 IOPS

� SPC-2 benchmark: Simulates heavy sequential workloads

– SVC 4.2 delivers over 50% better throughput than SVC 4.1: 7080 SPC-2 MB/s

� SVC leads the industry in both SPC benchmarks

� High SVC throughput supports virtualizing multiple storage systems

Measurements conducted using 8-node SVC configurations; SVC 4.1 used 8F4 nodes; SVC 4.2 used 8G4 nodes.For more information, see www.storageperformance.org/results

Infrastructure Simplification with SVCTraditional SAN

� Capacity is isolated in SAN islands

� Multiple management points

� Poor capacity utilization

� Capacity is purchased for, and owned by individual processors


� Combines capacity into a single pool

� Uses storage assets more efficiently

� Single management point

� Capacity purchases can be deferred until the physical capacity of the SAN reaches a trigger point.

Non-disruptive Data Migration with SVC

Traditional SAN

1. Stop applications

2. Move data

3. Re-establish host

connections

4. Restart applications


1. Move data

Host systems and applications

are not affected.

Business Continuity with SVC

Traditional SAN

� Replication APIs differ by vendor

� Replication destination must be

the same as the source

� Different multipath drivers for each

array

� Lower-cost disks offer primitive, or

no replication services


� Common replication API, SAN-wide,

that does not change as storage

hardware changes

� Common multipath driver for all

arrays

� Replication targets can be on lower-

cost disks, reducing the overall cost

of exploiting replication services

– Offers great implementation flexibility

� Operates between SVC clusters at each site

– Local and remote volumes may be on any SVC supported disk systems

� Long distance asynchronous remote mirroring function

� Up to 8000km distance between sites for business continuity

� Does not wait for secondary I/O before completing host I/O

– Helps reduce performance impact to applications

� Designed to maintain consistent secondary copy at all times

– Once initial copy has completed

� Built on Metro Mirror code base

� Metro and Global Mirror delivered as single feature

– Offers great implementation flexibility

� Operates between SVC clusters at each site

– Local and remote volumes may be on any SVC supported disk systems
