NOTE: When you specify two tiers, for the purposes of analysis and data movement only the order of the tiers matters, not the actual tier number. For example specifying tiers 0 and 1 is equivalent to specifying 0 and 2 or 1 and 2. The lower numbered tier is considered the faster tier and the higher numbered tier is considered the slower tier. However, you should consider whether you may want to add a tier in the future, and if so what tier number that is likely to be, and leave out that tier number for the two tier configuration. For example, if you have SSD PDs and NL PDs, you may want to use SSD PDs for the tier 0 CPG, NL PDs for the tier 2 CPG, and leave tier 1 empty for the possibility of a CPG using FC PDs. The maximum space in GiB for the tier allows you to limit how much space in a tier is available for a given configuration. If you do not want to place a limit on the amount of space for a tier, you can enter a large value that is unlikely to be exceeded. Adaptive Optimization looks at several limits on the CPG: • The CPG allocation (hard) limit • The CPG warning limit • The AO space limit for the tier Adaptive Optimization takes the minimum of these limits and treats that as a space limit for the CPG and attempts to keep the total LD used space in the CPG below this limit (by a margin of about two times the grow size of the CPG). The TPVV usr space and Snapshot copy space for a CPG can be examined using the HP 3PAR OS CLI showvv -cpg alloc command. Since this space may need to grow on demand as the host writes the VV or snapshot, you should make sure that the CPG associated with the TPVV usr space and Snapshot copy space has room to grow (i.e., you should not associate TPVV usr space with a space-constrained SSD CPG). As an example, suppose your default TPVV usr cpg is CPG1 (tier 1), and you set a tier space limit on tier 1 to 100 GB. In between iterations of Adaptive Optimization, suppose the TPVVs grow and the space used in CPG1 grows to 110 GB. Also, suppose the grow size is 8 GB. When the next iteration of Adaptive Optimization runs, it will try to reduce the used space in CPG1 to 100-(2*8) = 84 GB, and attempts to move 26 GB from that tier to ether tier 0 or tier 2. The reason it needs two times the grow size is that the HP 3PAR StoreServ Storage does not currently allow usr space for fully provisioned VVs and Snap space or TPVV space to be on the same LDs so it needs the equivalent of the grow size for both parts. This can be inefficient, especially for SSD CPGs that are not used for automatic growth, only Adaptive Optimization movement. Therefore, it is recommended that you decrease the grow size for SSD CPGs to the smallest possible amount, Configuring Adaptive Optimization 183

NOTE:

When you specify two tiers, for the purposes of analysis and data movement only the

order of the tiers matters, not the actual tier number. For example specifying tiers 0 and 1 is

equivalent to specifying 0 and 2 or 1 and 2. The lower numbered tier is considered the faster tier

and the higher numbered tier is considered the slower tier.

However, you should consider whether you may want to add a tier in the future, and if so what

tier number that is likely to be, and leave out that tier number for the two tier configuration. For

example, if you have SSD PDs and NL PDs, you may want to use SSD PDs for the tier 0 CPG, NL

PDs for the tier 2 CPG, and leave tier 1 empty for the possibility of a CPG using FC PDs.

The maximum space in GiB for the tier allows you to limit how much space in a tier is available

for a given configuration. If you do not want to place a limit on the amount of space for a tier, you

can enter a large value that is unlikely to be exceeded.

Adaptive Optimization looks at several limits on the CPG:

•

The CPG allocation (hard) limit

•

The CPG warning limit

•

The AO space limit for the tier

Adaptive Optimization takes the minimum of these limits and treats that as a space limit for the

CPG and attempts to keep the total LD used space in the CPG below this limit (by a margin of

about two times the grow size of the CPG).

The TPVV usr space and Snapshot copy space for a CPG can be examined using the HP 3PAR

OS CLI

showvv -cpg

alloc command. Since this space may need to grow on demand as the

host writes the VV or snapshot, you should make sure that the CPG associated with the TPVV usr

space and Snapshot copy space has room to grow (i.e., you should not associate TPVV usr space

with a space-constrained SSD CPG).

As an example, suppose your default TPVV usr cpg is CPG1 (tier 1), and you set a tier space limit

on tier 1 to 100 GB. In between iterations of Adaptive Optimization, suppose the TPVVs grow

and the space used in CPG1 grows to 110 GB. Also, suppose the grow size is 8 GB. When the

next iteration of Adaptive Optimization runs, it will try to reduce the used space in CPG1 to

100-(2*8) = 84 GB, and attempts to move 26 GB from that tier to ether tier 0 or tier 2.

The reason it needs two times the grow size is that the HP 3PAR StoreServ Storage does not currently

allow usr space for fully provisioned VVs and Snap space or TPVV space to be on the same LDs

so it needs the equivalent of the grow size for both parts. This can be inefficient, especially for

SSD CPGs that are not used for automatic growth, only Adaptive Optimization movement. Therefore,

it is recommended that you decrease the grow size for SSD CPGs to the smallest possible amount,
