Page 13: Introduction To Provisioning
Provisioning a storage system requires balancing the costs of the solution with the benefits that the solution provides. The following is an overview of provisioning strategies that you can implement on the HP XP7 Storage to support your business. About provisioning Provisioning is a method of managing storage system devices or volumes.
Page 14: Disadvantages
The alternative is to use a host-based Logical Volume Manager (LVM) when the planned workloads require either more space or IOPS capacity than the individual physical volumes can provide. LVM is the disk management feature available on UNIX-based operating systems, including Linux, that manages their logical volumes.
Page 15: When To Use Fixed-Sized Provisioning
When to use fixed-sized provisioning Fixed-sized provisioning is a best fit in the following scenarios: When custom-sized provisioning is not supported. Custom-sized provisioning Custom-sized (or variable-sized) provisioning has more flexibility than fixed-sized provisioning and is the traditional storage-based volume management strategy typically used to organize storage space.
Page 16: Thin Provisioning Overview
Virtual LUN software is used to configure custom-sized provisioning. For detailed information, see “Configuring custom-sized provisioning” (page 45). Thin Provisioning Overview Thin provisioning is an approach to managing storage that maximizes physical storage capacity. Instead of reserving a fixed amount of storage for a volume, it simply assigns capacity from the available physical pool when data is actually written to disk.
Page 17: Thin Provisioning Concepts
Thin Provisioning concepts Thin Provisioning is a volume management feature that allows storage managers and System Administrators to efficiently plan and allocate storage to users or applications. It provides a platform for the array to dynamically manage data and physical capacity without frequent manual involvement.

SSD, SAS, and external volumes. This eliminates unnecessary costs. Reduces As the expected physical disk capacity is HP XP7 Storage product licenses are based on management labor purchased, the unused capacity of the storage used capacity rather than the total defined...
Page 19: Smart Tiers
Smart Tiers After using Thin Provisioning software to virtualize LUs and pool storage into a thin provisioning strategy, the array now has all the elements in place to offer automatic self-optimizing storage tiers provided by Smart Tiers. Using Smart Tiers, you can configure a storage system with multiple storage tiers using different kinds of data drives, including SSD, SAS, and external volumes.
Page 20: When To Use Smart Tiers
The following figure illustrates the basic tier concept. When to use Smart Tiers Smart Tiers is the best fit in an environment in which Thin Provisioning is a good fit. For detailed information, see “Configuring thin provisioning ” (page 62). Data retention strategies After provisioning your system, you can assign access attributes to open-system volumes to protect the volume against read, write, and copy operations and to prevent users from configuring LU...

Page 24: Managing Virtual Storage Machine Resources
For example, if nondisruptive migration is used to migrate a storage system to HP XP7 Storage, the virtualized storage system is the migration source storage system. The migration source storage system is created in the migration target storage system.
Page 25: Provisioning Operations For Resources In A Virtual Storage Machine
However, provisioning operations that specify IDs of virtualized resources are limited. For details about data management operations for virtualized resources, see the HP XP7 RAID Manager User Guide.
Page 26: Program Product Operations For Resources In A Virtual Storage Machine
However, data management operations that specify IDs of virtualized resources are limited. For details about data management operations for virtualized resources, see the HP XP7 RAID Manager User Guide.
Page 27: Related Topics
If you select Enable in Virtualization Management Settings and can set a virtual LDEV ID, set the starting virtual LDEV ID for Initial Virtual LDEV ID. A virtual LDEV ID that is not used in the virtual storage machine is assigned at the interval specified in Interval, sequentially starting from the specified virtual LDEV ID.
Page 28: Configuring Resource Groups
3 Configuring resource groups Abstract The Storage Administrator can divide a provisioned storage system into resource groups that allow managing the storage system as multiple virtual private storage systems. Configuring resource groups involves creating resource groups, moving storage system resources into the resource groups, and assigning resource groups to user groups.
Page 29 The Security Administrator creates user groups. See the HP XP7 Remote Web Console User Guide for more information. The Security Administrator assigns the resource groups to user groups. See the HP XP7 Remote Web Console User Guide for more information.

If you exceed the licensed capacity, you will be able to use the additional unlicensed capacity for 30 days. For more information about temporary license capacity, see the HP XP7 Remote Web Console User Guide. Pool requirements A pool is a set of volumes reserved for storing Thin Provisioning write data.
Page 63: Pool-Vol Requirements
Items Requirements 4200 in the formula is the management area size of the pool-VOL with System Area. Total Number of pages = Σ(floor(floor(pool-VOL number of blocks ÷ 512) ÷ 168)) for each pool-VOL. floor( ): Truncates the value calculated from the formula in parentheses after the decimal point. However, the upper limit of total capacity of all pools is 12.3 PB if shared memory is installed.
Page 64 Cautions: HP recommends that drives with different types do not coexist in the same pool. If multiple pool-VOLs with different drive types are registered in the same pool, the I/O performance depends on the drive type of the pool-VOL to which the page is assigned. Therefore, if different drive types are registered in the same pool, ensure that the required I/O performance is not degraded by using less desirable drive types.

CAUTION: If you delete a pool, its pool-VOLs (LDEVs) will be blocked. Blocked volumes must be formatted before use. CAUTION: If the V-VOL data is migrated through the host, unallocated areas of the volume may be copied as well. The used capacity of the pool increases after the data migration because the areas that were unallocated before the data migration have become allocated areas due to migration.
Page 77: Tier Monitoring And Data Relocation
Because assigning data to particular media may be an ongoing and complex activity, Smart Tiers software automatically manages the process based on user-defined policies. As an example of the additional implementation of tiered storage, tier 1 data (such as mission-critical or recently accessed data) might be stored on expensive and high-quality media such as double-parity RAIDs (redundant arrays of independent disks).
Page 78: Tier Monitoring And Relocation Cycles
Tier monitoring and relocation cycles Performance monitoring and tier relocation can be set to execute in one of two execution modes: Auto and Manual. You can set up execution modes, or switch between modes by using either Remote Web Console or RAID Manager. In Auto execution mode, monitoring and relocation are continuous and automatically scheduled.
Page 79 the collection of monitoring information and tier relocation operations are started again. These operations are then performed at 1-hour intervals. Figure 7 Collection of monitoring data to tier relocation workflow in auto execution mode In auto execution mode, the collection of monitoring data and tier relocation operations are performed in parallel in the next cycle.
Page 80 Figure 8 Collection of monitoring data to tier relocation workflow in manual execution mode Case 1: If the second collection of the monitoring information is finished during the first tier relocation, the latest monitoring information is the second collection. In that case, the first collection of monitoring information is referenced only after the first tier relocation has completed.
Page 81: Tier Relocation Flow
In that case, the third collection of the monitoring information is started after the first tier relocation is stopped or tier relocation has completed. The collection of the monitoring information is not started under these conditions as well: When the second tier relocation is performed, the fourth collection of monitoring information cannot be started.
Page 82 Explanation of the relocation flow: Allocate pages and map them to THP V-VOLs Pages are allocated and mapped to THP V-VOLs on an on-demand basis. Page allocation occurs when a write is performed to an area of any THP V-VOL that does not already have a page mapped to that location.
Page 83: Tier Relocation Rules, Restrictions, And Guidelines
Determine the tier range values The page is allocated to the appropriate tier according to performance monitoring information. The tier is determined as follows. Determine the tier boundary The tier range value of a tier is calculated using the frequency distribution graph. This acts as a boundary value that separates tiers The pages of higher I/O load are allocated to the upper tier in sequence.
Page 84: Conditions For The Discontinuance Of Performance Monitoring Or Tier Relocation
allocated during the monitoring cycle. Pages that are not allocated during performance monitoring are not candidates for tier relocation. Tier relocation can be performed concurrently on up to eight pools. If more than eight pools are specified, relocation of the ninth pool starts after relocation of any of the first eight pools has completed.

New page assignment: New pages are assigned based on a number of optional settings. Pages are then assigned to the next lower tier, leaving a buffer area (2% per tier by default) for tier relocation. Once 98% of capacity of all tiers is assigned, the remaining 2% of the buffer space is assigned from the upper tier.

Reserved pages for relocation operation: A small percentage of pages, normally 2, are reserved per tier to allow relocation to operate. These are the buffer spaces for tier relocation. Tier relocation workflow: Tier relocation is performed taking advantage of the buffer space allocated for tier relocation, as mentioned above.
Page 89 The following illustrates tier relocation processing in Manual execution mode: Notes on performing monitoring You can collect the monitoring data even while performing the relocation. After stopping the monitoring, the tier range is automatically calculated. The latest available monitoring information, which is collected just before the relocation is performed, is used for the relocation processing.

Page 102: Example Of Reserving Tier Capacity
Example of reserving tier capacity The reservation priority depends on the level of tiering policy. The following figure illustrates the reservation priority. Tiers are reserved in order of priority from (1) to (7) in the figure. If the pool-VOL capacity is deficient when you reserve a tier, the nearest tier of your specified tier is allocated. If you specify two tiers like level 2 or level 4 of the tiering policy, first of all the upper tier is reserved.
