Logical Building Blocks
The Storwize V3700 uses basic storage units called
managed disks and collects them into one or more
storage pools
These storage pools then provide the physical capacity to
create volumes for use by hosts

Storage Pool
Volume A
When the managed disks are
added into storage pools, the
managed disks are split into
chunks of storage known as
extents
The size of these extents is a
property of the storage pool
– Default is 256MB
Whenever you create a new
volume you must pick a single
storage pool to provide the
physical capacity
By default the created volume
will stripe all of it’s data across
all the managed disks in the
storage pool as shown on the
left diagram
Thin provisioned volumes
consume extents only as actual
data is written to disk

Default Configuration
This is the default configuration that is automatically built during
the initial configuration of the V3700
– Not an optional choice
A one click GUI setup exists to configure all drives into RAID arrays
– Solid state drives will be configured as RAID 1 with 2 members and 1 spare
– SAS drives will be configured as RAID 5 with 8 members and 1 spare
– Near line SAS drives will be configured as RAID 6 with 12 members and 1
spare
All members of an array will have the same drive class
– All SAS, all SSD or all NL SAS
– Same RPM and capacity
One storage pool will be created for each drive class
Different configuration requires the default to be deleted before
creating.
© 2010 IBM Corporation
24
Advanced Technical Skills (ATS) North America
Supported RAID levels
Storwize V3700 will support the following RAID levels:
– RAID 0 (striping, no redundancy)
– RAID 1 (mirroring between 2 drives)
– RAID 5 (striping, can survive one drive fault)
– RAID 6 (striping, can survive two drive faults)
– RAID 10 (RAID 0 on top of RAID 1)
More details about the what the RAID levels actually mean is
available at URL below:
– http://en.wikipedia.org/wiki/RAID
© 2010 IBM Corporation
25
Advanced Technical Skills (ATS) North America
Creating a RAID Array
In Storwize V3700 a RAID array is created at the point that you
add the array into the pool
When the array is created a single managed (a.k.a Mdisk) is
created for the full capacity of the array
Wizards and Pre-sets are available to suggest configurations to
users based on the hardware attached to the system
Currently there is no way to grow an existing array or change the
RAID level of an array
– E.g. Can’t grow a 4+P RAID-5 array to a 6+P array
– E.g. Can’t convert a 7+P RAID-5 array to a 4+4 RAID-10 array or vice versa
– Requires removing array from pool and recreating it larger or with different
RAID level
If the Mdisk built on internal storage is removed from the pool,
then the array and the associated managed disk is unconfigured
– Drives go back to candidate status to be used to create another array
© 2010 IBM Corporation
26
Advanced Technical Skills (ATS) North America
Deleting an Mdisk from a V3700 Storage Pool
Deleting a Mdisk from a storage pool
– Internal Mdisk require you delete them using the RAID array functions not the
Mdisk ‘right click’ and ‘Remove from pool’ which will be grayed out
• Internal Mdisks are RAID arrays and when you delete the Mdisk from a pool the array is
deleted as well and the member drives return to candidate state
© 2010 IBM Corporation
Advanced Technical Skills (ATS) North America
Spare Drive Design
Spare drives are global spares
– This means that any spare which is at least as big as the drive which is
being replaced can be used in an array
• Thus a SSD array with no SSD spare available would use a HDD spare
The spare system will prefer best possible match
based on the following parameters:
– Technology type
• SAS vs SSD vs. NL-SAS
– Speed/RPM
– Capacity
– Location
Each array has a spare goal property
– Indicates how many spares must be available to protect the array
– If the number of spares drops below the goal then alert sent to notify
admin

Replacing a physical drive
In existing entry level controllers, it is often the case that physically replacing
the drive in the slot is all that is required for a drive replacement.
In Storwize V3700, additional software steps are required to make the system
use the newly inserted drive.
If the drive is replaced under guidance from the Directed Maintenance
Procedure (DMP), these actions will be automatically performed by the DMP.
– Using DMP for all hardware replacement is basically required to make process as easy as
possible for the customer
– Do not just pull the bad part(s) and replace them without guidance from the procedures.
If the drive is a perfect replacement (matches all of the member goals)
then RAID will automatically queue the drive to be included into the
array
– If the array is still rebuilding onto a spare then the rebuild will be completed first
– If the array is fully redundant (all members present in the array) Then the spare will be
exchanged with the replaced drive
• A member exchange swaps the data between two drives so that a member can be replaced
concurrently without removing redundancy
Array width will grow by one drive during this process
– If there had not been a suitable spare in the system, then the array will be rebuilt to include the
replaced drive

FlashCopy Overview
Three types of FlashCopy are provided
Standard “Full image” copy – creates a complete image copy of
the source
Incremental Flash Copy only copies changes since previous
start
– Significant reduction in time to achieve independent copy after initial full copy
“Nocopy” copy – Only copies the change data of either the
source or the target to the repository
Reverse FlashCopy – Offers ability to restore to a given point
Uses a bitmap with a grain size of 256K (default) or 64K
© 2010 IBM Corporation
Advanced Technical Skills (ATS) North America
V3700 Base FlashCopy Limit
By default, the FlashCopy limit is 64.
– This restriction can be lifted on the V3700 with a license in
the future.
The limit needs to be explained carefully:
– It's not 64 mappings or 64 volumes in FC mappings.
– It is the sum total of all the “volume counts” for all the FC
groups for the system
• “Volume count” is the number of member volumes involved in the
FC group minus one.
• Do not permit the sum of the total per-graph scores to exceed 64.”

Direct Attach Fibre Channel
The V3700 supports direct attach fibre channel for many hosts
– Lower the cost of using high speed fibre channel
A maximum of 4 redundant fibre channel hosts can be directly
attached.
Closely matches the direct connect capabilities of the DS3500
– With the exception of AIX direct connect support
The full interoperability list will be posted to the web upon GA.
– Expect a fairly extensive interoperability matrix.
•
AIX direct connect support is one of the exception
– Some host types will be phased into the mix
For current list of all supported host and configurations see
the IBM System Storage Interoperation Center (SSIC) at:
http://www-03.ibm.com/systems/support/storage/ssic/interoperability.wss
Cannot directly attach a V3x00 to a V7000 for a direct attach

Licensed Machine Code
V3700 software is delivered as “Licensed Machine Code”
rather than as “Software”.
Under IBM rules, this means that users do not have to
purchase and install a separate license to use the system.
The term “Software” is replaced with “machine code”
throughout all CLI help/documentation/output and errors.
– CLI names that have “software” remain, e.g. applysoftware, but the help will
say “applysoftware – Upgrades the system to a new level of machine code”
There is no EULA to be accepted as part of the initial setup.
The following commands have changed some field
headings:
– sainfo lsservicestatus
– svcinfo lsnodevpd

Notes:
Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will
experience will vary depending upon 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 throughput improvements equivalent to the performance ratios stated here.
IBM hardware products are manufactured from new parts, or new and serviceable used parts. Regardless, our warranty terms apply.
All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved. Actual
environmental costs and performance characteristics will vary depending on individual customer configurations and conditions.
