InServ Concepts for Volume Management
Section Content covers:
– InServ Chunklet/Physical disk– InServ RAID 1 – InServ RAID 5 – InServ RAID MP (RAID 6)– Virtual Volumes, VLUNS (LUNS)– Logical disks (LDs)
Serving Information3PAR Company Confidential
Disks are broken up into 256 MB fine grained Chunklets
“Chunklets”… 256MB make 3Par Virtualized Storage Arrays and Fast
Increase performance over traditional methods like Hyper / Meta’s by using uniformed fine grain 256 MB data “Chunklets”
No wasted space
Enables Hosts to have faster access to data across drives
Allows for performance optimized and easier Array management
Maximizes Throughput in MB’s and IOP’s

3PAR RAID 1 Concepts
• RAID 1 is “mirrored” data
• Data is written as “paired” chunklets
• Each “chunklet” on the RAID set is on a different physical disk
Setsize = 2
Default size (RAID 1)
Usable space = 256 MB

Serving Information3PAR Company Confidential
3PAR RAID 5 Concepts
• RAID 5 uses parity to reconstruct data• RAID 5 uses a setsize of 4 by default
Setsize = 4 (3+1)
Default size (RAID 5)
Usable space = 768 MB (3*256)

Usable space = 2048 MB (8*256)
Serving Information3PAR Company Confidential
3PAR RAID Multi Parity (MP) Concepts
• RAID MP uses parity (double parity – can deliver data in a double disk failure) to reconstruct data and performed in the ASIC XOR engine
• RAID MP only supports two setsizes ( 8 and 16)
• The default set size of 8 has the same data to parity ratio as the default RAID-5 set size of 4 -- 3:1 in both cases.

Thin Provisioning
Serving Information3PAR Company Confidential
Objectives
• At the end of this presentation the user should be able to :
– Explain the benefits of Thin Provisioning– Understand the concepts of Thin Provisioning– Set-up a Common Provisioning Group (CPG)– Create a Thin Provisioned Virtual Volume (TPVV)– Manage Alerts for CPG– Understand Best Practices of CPG
Serving Information3PAR Company Confidential
Thin Technologies
• Thin Conversion - Rapid migration from Fat to Thin allows for easy conversion from
legacy storage environments at line speeds Preserve service levels or performance impact during
Migrations• Thin Persistence - Reduce storage capacity costs by
allowing “thin” volumes to stay “thin”
• Thin Copy
Reclamation - Reduce storage capacity costs by reclaiming storage capacity
that is deleted but still “locked” in allocated space
Serving Information3PAR Company Confidential
Thin Conversion
• Thin your online SAN storageup to 75%
• A practical and effective solution to eliminate costs associated with:• Storage arrays and capacity• Software licensing and support• Power, cooling, and floor space
• Unique 3PAR Gen3 ASIC with built-in zero detection delivers:• Simplicity and speed – eliminate the time & complexity of getting
thin• Choice - open and heterogeneous migrations for any-to-3PAR
migrations• Preserved service levels – high performance during migrations
Serving Information3PAR Company Confidential
Thin Persistence
• Non-disruptive and application-transparent “re-thinning” of thinprovisioned volumes
• Thin “insurance” against unexpected or thin-hostile application behavior
• Returns space to thin provisioned volumes and to free pool for reuse
• Unique 3PAR Gen3 ASIC with built-in zero detection delivers:• Simplicity – No special host software required. Leverage standard
file system tools/scripts to write zero blocks.• Preserved service levels – zeroes detected and unmapped at line
speeds
Serving Information3PAR Company Confidential
Thin Copy Reclamation
• Online thin copy “re-thinning”
• Capacity can be freed from Thin Copies as they age and are deleted • Full/Virtual/Remote Copies
• Minimal performance overhead
• Supported on all InServs • T, S, F and E-class • Available for all supported hosts• No special host software required
Serving Information3PAR Company Confidential
Thin-Reclaim Reclaim
• How previously thin-provisioned SD/SD2 space becomes unused?
– Remove snapshot, and thus copy space is less utilized
– Zero detection (thin built-in), zero cmp filled
Serving Information3PAR Company Confidential
3PAR Thin Provisioning
• Offers a simple solution to the problem of unused allocated capacity
• Allows IT departments to safely allocate to an application as much “virtual” logical capacity as conceivably needed
• Actual “physical” capacity is drawn from a common pool called a Common Provisioning Group (CPG)
• The physical capacity drawn from the CPG relates directly to Application writes (dedicate on write)

Common Provisioning Group (CPG)
• A virtual pool of logical disks
• Automatically provisions logical capacity to Snapshot Administration (SA) and Snapshot Data (SD)
• Snapshot Data is the Virtual Volumes User Space
• Careful planning and monitoring is essential to manage space
• 3PAR provides many “Safety” mechanisms to help manage CPGs
Serving Information3PAR Company Confidential
Thin Provisioned Virtual Volumes (TPVVs)
• TPVVs behave like traditional VVs – the differences are transparent to the host
• Virtual capacity is represented to host servers and applications as a Virtual Volume
• A TPVV has no user space
• A base TPVV users space is mapped “on demand” to a Snapshot Data (SD) on a copy-on-write basis
• The Snapshot Administration (SA) and SD spaces of a TPVV are always associated with a CPG
• The same ease-of-use for VVs exist with TPVVs

Note: For a Full listing of <createcpg> command options refer to the “OS CLI Reference”
Serving Information3PAR Company Confidential
Growth Increment Considerations
• Should not exceed available space on your system
• The nature of the data running on the system
• The number of CPGs in the system
• The number of volumes associated with those CPGs
• Anticipated growth rate of the volumes associated with the CPG
Serving Information3PAR Company Confidential
Growth Increment Defaults and Minimums
Note: A smaller growth increment carries less risk in that it can prevent the CPG from automatically allocating a large amount of space at an inopportune time.
* If not sure – discuss with your SE.
Serving Information3PAR Company Confidential
Determining Space Usage
• Showcpg -rAt Creation
After TPVV Creation
Serving Information3PAR Company Confidential
CPG Growth Warning
• When a CPG approaches its “growth” warning an “alert” is generated
• The Administrator should check and determine if any action is required upon receiving a “growth” warning
• The InServ will suspend writes when a CPG is out of space
• An Administrator can add physical disk space or limit the future growth of volumes that draw from the CPG
Serving Information3PAR Company Confidential
CPG Growth Limit
• The InServ Administrator must be very careful when setting “Growth Limits”
• The Administrator can set a Growth limit greater than the systems physical disk space
• Recommendation: Do not allow a volume that draws form a CPG to exceed its growth limit
System Alert: If a volume that draws from the CPG reaches the CPG’s growth limit, an “alert” is generated notifying you that all logical capacity for the CPG has been consumed
Serving Information3PAR Company Confidential
Viewing Alerts Using InForm GUI
• Alerts can be seen by viewing the “Alert Pane” or selecting “Events” from InForm GUI
Serving Information3PAR Company Confidential
Thinly Provisioned Virtual Volumes
• A base volume capable of responding to host write requests by allocating space on demand in small increments
• Structured so that each volumes virtual size (the size that the volume presents to the host) always remains the same
• The storage behind the volume is allocated on demand
Serving Information3PAR Company Confidential
TPVV Components
• Snapshot Data Space
– Known as copy space– Contains the volumes user data and snapshot copy
data– A TPVV can have its user data or VC data in separate
CPGs (different QOS)
• Snapshot Administration
– Known as admin space– A Pointer file that “points” to VC or TPVVs
Serving Information3PAR Company Confidential
Creating a TPVV
• Creating a TPVV where the VC space and the user space are in the same CPG
createvv –tpvv –snp_cpg Raid1FC Raid1FC TPVV_oracle_log 50G
• Creating a TPVV where the VC space is in a different CPG than the user space
createvv –tpvv –snp_cpg Raid5NL Raid1FC TPVV_Oracle 50G
Serving Information3PAR Company Confidential
Editing CPG Parameters
• The following CPG parameters can be edited:
– Growth increment – Growth warning– Growth limit
• The following Logical disk parameters for CPG can be edited:
– RAID Type– Availability– Stepsize– Rowsize– Disk Filter
You can use “CLI” or “GUI” to make the changes. <setcpg> command is used to edit CPG parameters
Serving Information3PAR Company Confidential
Removing a CPG
• A CPG can be removed if no volumes are drawing Logical Disks from it
• To remove CPG using GUI (right click):
• To remove using CLI– <removecpg> command

Why Host Personas
• Different operating systems require slightly different behaviors both from the port level and the SCSI layer
• Host persona splits this into SCSI layer behaviors (host persona capabilities) and port behavior settings (via “controlport config”)
• Multiple host types can share a single InServ Storage
Server port.
• Each host initiator gets its unique FC/SCSI level behavior.
Serving Information3PAR Company Confidential
Available Host Personas
For HPUX, AIX, and ONTAP all Host Personas are “Legacy Personas” since each OS was not going to take advantage of the new “Capabilities” of UARelLun, SesLun, and RTPG.
Serving Information3PAR Company Confidential 77
Host Personas – Some Details
• Host personas are tied to the host name and identified by the host persona number
• The host persona number can be set when the host is created or can be modified later
• The host personas can be created, modified, removed or displayed using the IMC or CLI commands
Serving Information3PAR Company Confidential 78
How Does It Work
• Controlport config sets existing and new loop attributes
– disk--initiator ports
– host--target ports
– rcfc--remote copy
– loop/point--connection topology
– unique_nwwn--ontap ports
Follow Implementation Guides (IGs) exactly when configuring hosts
