What is meant by Software Defined Storage?
 Software Defined Storage (SDS) key capabilities:
– Abstract and virtualize storage capabilities to provide a dynamic,
agile, and flexible storage SW platform. Software-based storage
capabilities operate across a variety of configurations and are
independent of HW and protocols.
– Standard interfaces and integration points to enable applications
to manage/leverage the storage capabilities.
– A holistic platform to enable fully integrating
compute/storage/network capabilities targeted at storage centric
solutions
 Software Defined Storage must be able to provide the ability to…
– Derive business value from all of your storage assets
– Drive consistency and drive down storage management / costs
– Create a flexible storage infrastructure
– Focus on the business and not IT

 Notes:
– At least one adapter card is required
– Up to three 8Gbps Fibre Channel adapters (12 ports)
– Up to four 16Gbps Fibre Channel adapters (8 ports)
– Up to one 10Gbps Ethernet/FCoE adapter (4 ports)
– Using any of slots 4-6 requires second CPU and 32GB cache upgrade

20. IBM Storage
10Gb Ethernet Card (FCoE and iSCSI)
 The new 4x port 10GbE card will only be supported in the new SVC DH8 and in the Storwize V7000 2076 -524
 The card is delivered with the SFPs fitted, unless it is a FRU.
 In SVC 7.3.0 we will only support 1 x 10GbE adapter in each of the platforms (see above)
 Only IBM supported 10Gb SFPs should be used
 Each adapter port has amber and green coloured LED to indicate port status (fault LED is not used in 7.3.0.)
 iSCSI access to volumes is possible via the customers 10 Gbps Ethernet network.
 FCoE frame routing should be done by FCoE Switch
 SVC doesn't support multihop FCoE

21. IBM Storage
16Gbps Fibre Channel Support
 Requires Storwize Family Software V7.4
 New dual-port 16Gbps Fibre Channel adapter supported on Gen2 Storwize V7000 Unified,Storwize V7000 Gen2 and SVC
DH8
 Connect to legacy 8Gbps servers or storage through switches
 Overall system throughput largely unchanged
 Up to double single-stream single port throughput (to 1.5GB/s)
can benefit analytics workloads
– Both ports are full bandwidth 16Gb
 SW (standard) and LW (optional) SFPs available
 MUST be plugged in to 16 Gb FC switch
– Auto negotiating to 8Gb requires RPQ
21

22. IBM Storage
Compression accelerator adapter
 Up to a total of 2 compression accelerator adapters can be installed, each additional adapter
installed will improve I/O performance when using compressed volumes
– Intel QuickAssist technology is used. IBM is the first in the industry to integrate this technology into
our products
– 2nd CPU and extra 32 GB of memory are compulsory with the compression accelerator adapter
 The use of compression accelerator adapters is compulsory (at least one) if users
wish to use compression on SVC DH8.
– For an I/O group containing a SVC DH8 with no compression accelerator, an attempt to create first
compressed volume will fail.
– The addnode command will also fail, if trying to add a SVC DH8 without a compression accelerator, to
an I/O group which has compressed volumes
22

23. IBM Storage
SVC DH8: Compression Support
• Base hardware:
• No RTC support
• Add hardware option 1: 2nd CPU, 1x Compression Accelerator adapter + 32GB memory:
• 8 cores dedicated to RTC
• 1 Compression Accelerator adapter
• 38GB memory for compression stack (32 additional + 6 from the SVC stack)
• Additional hardware option 2: 2nd Compression Accelerator
• 8 cores dedicated to RTC (same as for option 1)
• 2 Compression Accelerator adapters (doubles bandwidth)
• 38GB memory for compression stack (32 additional + 6 from the SVC stack)
• Note: The 2nd CPU is required to open the PCIe lanes as well as schedule traffic into and
out of the compression accelerator cards
23

24. IBM Storage
SVC DH8 – Expansion Enclosure 2145 24F
 With R1 and 730 – support 2 expansion enclosures per I/O Group
 Ports 1 and 3 of the 12 Gb SAS card can be used to attach 2U24 Expansion enclosures of
flash drives
 Only flash drives are allowed
 Expansion enclosures are physically identical to the V7000 Gen2 expansion enclosures,
but will have a different product ID
 SVC DH8 cannot use the V7000 Gen2 expansion enclosures, V7000 Gen2 cannot use the
SVC DH8 expansion enclosure

SVC - 2 Node (1IOG) Performance
SUMMARY: DH8 is 2x IOPs and up to 3x MB/s of CG8
SVC tests use FlashSystem 840 and 820 backend storage controllers
DH8 includes all 3 FC I/O Cards – scales linearly from 1, through 3 for bandwidth
Requires 2 cards for max IOPs – 1 card approx half, or roughly CG8 equivalent

 Compressed performance shows a range depending on I/O distribution
 Compressed performance is better than uncompressed in some cases because of
fewer I/Os to drives and additional cache benefits

30. IBM Storage
Statements of Direction
 The second CPU with 32 GB memory feature on SVC Storage Engine Model
DH8 provides performance benefit only when Real-time Compression is
used. IBM intends to enhance IBM Storwize Family Software for SVC to
extend support of this feature to also benefit uncompressed workloads.

48. IBM Storage
Easy Tier v3: Automated Storage Pool Balancing
 Any storage medium has
a performance threshold:
– Performance threshold means
once IOPS on a MDisk exceed
this threshold, IO response time
will increase significantly
 Knowing the performance
threshold we could:
– Avoid overloading MDisks by
migrating extents
– Protect upper tier's performance
by demoting extents when upper
tier's MDisks are overloaded
– Balance workload within tiers
based on utilization
– Use xml file to record the MDisk’s
threshold and make intelligent
migration decisions automatically
48

49. IBM Storage
Manage data growth to control costs
 Traditional (“fully allocated”) virtual disks use
physical disk capacity for the entire capacity of a
virtual disk even if it is not used
– Just like traditional disk systems
 With thin provisioning, physical disk capacity is
allocated and used when data is written
– Can significantly reduce amount of physical disk
capacity needed
 Can significantly improve existing disk systems
49
 Real-time compression can help freeze storage
growth or delay need for additional purchases
 Delivers 50% or better compression for data that
is not already compressed
 Compression helps reduce
– Storage purchase costs
– Rack space
– Power and cooling
– Software costs for additional functions
 Works with all virtualized storage assets

50. IBM Storage
Real-Time Compression is designed to:
– Work on Active Primary Data
– Dedicated platform for compression
Platform handles ALL heavy lifting associated with compression
– No performance impact
We modify a compressed file in-place efficiently
– No change in customer applications
Users nor admins need to change anything
– No change in processes
All compression happens in Real-Time NOT post processing
– Industry standard compression algorithm

 Target workloads:
– Database applications – Oracle, IBM DB2, Microsoft SQL Server, SAP
– Server/Desktop virtualization – VMware, KVM, Hyper-V
– Others – Engineering, Collaboration, Seismic, CAD
 Workloads to avoid:
– Applications storing compressed data – such as videos, images, newer MS-Office file formats, etc.
– Applications storing encrypted data*
 Target data compression savings (use Comprestimator):
– Above 40% – Recommended
– Below 40% – Evaluate workload
 I/O patterns:
– Random access – Recommended
– Sequential access – Recommended
 Performance:
– Use Disk Magic

Hybrid Use Cases: The Future of Storage Economics
The storage administrator supporting traditional
applications can configure SVC to use cloud storage
as a target for snapshots.
How? Once configured, the client can use cloud storage
like any other FlashCopy target.
For these use cases,
cloud storage is either
an OpenStack Swift
object store (like
Spectrum Scale with its
Swift interface)
deployed on or off
premises, or an
Amazon Web Services
S3 object store.
The storage administrator supporting new generation
applications can configure on-prem Elastic Storage to
utilize cloud storage as an additional storage tier
How? Once configured, the client can use cloud storage
like any other storage tier. Policies direct movement of cold
data to the cloud storage tier or application owners can
manually move data to that tier, for example to run a
temporary analytics job using cloud resources.
