Page 10: 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 11: Basic Provisioning
Basic provisioning Several basic provisioning techniques traditionally are used to manage storage volumes. These strategies are useful in specific scenarios based on user needs, such as whether you use open or mainframe storage systems, or you want to manually size your volumes. Basic provisioning relies on carving up physical storage into smaller units.
Page 12: Basic Provisioning Workflow
and I/O workload is balanced (each file is allocated to a different volume), then access contention is reduced and access performance is improved. In fixed-sized provisioning, all of the volume's capacity might not be used. Unused capacity on the volume will remain inaccessible to other users. If the custom-sized feature is used, smaller volumes can be created that do not waste capacity.

In 1,120 cylinders, 1,1 13 cylinders are defined as a user-cylinder, and 7 cylinders are defined as a control cylinder. To effectively create the CV of 3390-A, HP recommends that you specify multiples of 1,1 13 cylinders for the CV capacity. Virtual LVI specifications...
Page 36: Ssid Requirements
SSID requirements The storage system is configured with one SSID (Storage System ID) for each group of 64 or 256 devices, so there are one or four SSIDs per CU image. Each SSID must be unique to each connected host system. SSIDs are user-specified and are assigned during storage system installation in hexadecimal format, from 0004 to FEFF.
Page 37: Calculating The Size Of A 3390-V Volume
Calculating the size of a 3390-V volume To calculate the entire capacity of a CV, use the following formulas. For the user-specified-CV-capacity, specify the capacity of the user area in a CV. The resulting CV capacity is expressed in megabytes: ( ceil ( (user-specified-CV-capacity * 15) / 672) * 672 * capacity-of-a-slot ) / 1024 The value enclosed in ceil( ) must be rounded up to the nearest whole number.
Page 38: Management Area Capacity Of A Mainframe Volume
( ceil( ( (user-specified-CV-capacity + management-area-capacity) * 15 * capacity-of-a-slot) / boundary-value) * boundary-value) / 1024 The value enclosed in ceil( ) must be rounded up to the nearest whole number. The user-specified-CV-capacity is the capacity of the user area in a CV expressed in cylinders.
Page 39: Configuring Volumes In A Parity Group
Configuring volumes in a parity group For RAID 5 (7D+1P), RAID 6 (6D+2P), or RAID 6 (14D+2P) a maximum of 2,048 fixed-size volumes (FVs) and a certain amount of free space are available in one parity group. For other RAID levels, a maximum of 1,024 FVs and a certain amount of free space are available in one parity group.
Page 40: Create Ldev Function

About formatting LDEVs The LDEV Format function, which includes Normal Format, Quick Format and Write to Control Blocks. These functions format volumes, including external volumes. Before formatting volumes, ensure that the volumes are in blocked status. The following table lists which formatting functions can be used on which LDEV types. Formatting function Corresponding volume Normal Format...
Page 52: Quick Format Specifications
Particularly, in the following cases of quick format operations, due to the load concentration on a specific component at the same time, the I/O performance of the host may decrease while performing of the quick format. In a configuration that satisfies both of these conditions, many quick formats started at the same time.
Page 53: Write To Control Blocks Function
Item Description groups that have not undergone but can undergo Quick Format, use the following formula: 72 - X -Y Where: Xindicates the number of parity groups on which Quick Format is being performed. Yindicates the number of parity groups where all volumes are blocked during the Quick Format.

THP V-VOL. 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 Z write data.
Page 60: Pool-Vol Requirements
Items Requirements The capacity of the pool (MB) = Total number of pages * 38 - 3800. 3800 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 ÷ 116) ÷...
Page 61 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.
Page 62: Thp V-Vol Requirements
The following requirements are important when increasing the THP V-VOL capacity: The emulation type is 3390-A. The THP V-VOL to be increased is not shared with the HP XP7 Storage product that does not allow increasing the THP V-VOL (See “Increasing THP V-VOL capacity”...

If you specify the THP V-VOL as the source volume, you must not specify the THP V-VOL that uses the same pool of the source volume. For details about the migration of THP V-VOLs used in the following pairs, see the HP XP7 Auto LUN User Guide.
Page 70: Smart Tiers Z
CAUTION: If you delete a pool, its pool-VOLs (LDEVs) will be blocked. Blocked volumes must be formatted before use. CAUTION: When data migration is done on a file-by-file basis, perform the operation to reclaim zero pages if necessary. In the case of a volume copy or the physical copy, the operation to reclaim zero pages is unnecessary.
Page 71: Tier Monitoring And Data Relocation
Tier monitoring and data relocation Smart Tiers uses tiers to manage data storage. It classifies the specified drives in the pool into tiers (storage hierarchy). Up to three tiers can be defined in a pool depending on the processing capacity of the data drives.
Page 72 In Auto execution mode, monitoring and relocation are continuous and automatically scheduled. In Manual execution mode, the following operations are initiated manually. Start monitoring Stop monitoring and recalculate tier range values Start relocation Stop relocation In both execution modes, relocation of data is automatically determined based on monitoring results.
Page 73 Figure 6 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. Data from these parallel processes are stored in two separate fields.
Page 74 Figure 7 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 75: 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 76 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 77: 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 78: 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.

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.
Page 98: Notes On Tiering Policy Settings
Tier reservation Tiering policy Reserved tier priority From 4 to 29 From Level6(6) to Level31(31) The custom policy whose number is small is prioritized. Tier 1: From Level6(6) to Level31(31), each of the Tier1 Min values are reserved. Tier 2: From Level6(6) to Level31(31), each of values that deducted the total value of Tier1 Max and Tier3 Max from 100(%) are reserved.
