If a compressed volume exists within a common provisioning group (CPG), then the CPG i s not available for use in an AO configuration. BTW there’s a min IOps setting to prevent demotion due to minimal access. I would however say it would be cleaner to create a new CPG, and then to use dynamic optimization to move the volumes over. Timing is a key consideration. Adaptive Optimization (AO) is 3PAR’s disk tiering technology, which automatically moves the hottest most frequently accessed blocks to the fastest disks and at the same time moves the infrequently accessed cold blocks of data to slower disks. HPE 3PAR Adaptive Flash Cache feature is included as part of the HPE 3PAR OS and is supported on all HPE 3PAR StoreServ Storage sys tems that are supported with HPE 3PAR OS 3.2.1 and above. Hi, I have a 3 tier AO config. You can create 2 tier AO between FC and SSD or FC an… When you hit this level AO will not move any more data to those disks. Dynamic optimization is much simpler to understand. can we do the AO confugration on existing CPG ? I 'll plan to delete it. 3PAR OS includes the data movement engine, however it has to be unlocked either using Dynamic or Adaptive Optimization. The HP 3PAR Adaptive Optimization Software is a granular, policy-driven, autonomic storage tiering solution that delivers service level optimization for virtual and cloud data centers to reduce cost while increasing agility and minimizing risk. note: 3par_as49_datastore and 3par_optilogistic_datastore is not used. whether I start AO do system occur problem? to take advantage of HP 3PAR StoreServ’s unique features such as vSphere integration, HP 3PAR Thin Provisioning technologies, Dynamic and Adaptive Optimization, Priority Optimization, and HP 3PAR Recovery Manager for VMware to How do you know if your 3PAR’s Adaptive Optimization (AO) is optimized? The Managing HPE 3PAR StoreServ II course is designed for the experienced HPE 3PAR administrator. HPE 3PAR Smart SAN. HPE 3PAR Adaptive Optimization (AO). HPE 3PAR Virtual Lock. If the access pattern of your data is truly random each day Adaptive Flash Cache may help to soak up some of the hits and can be used conjunction with AO. Then when its the original CPG is empty you would be able to delete it. Now I am very worry disk SSD 100GB alocate 98%. In March 2010, the company introduced 3PAR Adaptive Optimization, the industry's first implementation of autonomic storage tiering for cost optimization in high-end storage systems, targeted at enterprises and service providers. HPE 3PAR Smart SAN. OS footprint, installed programs etc) with some data going to Tier 1 eventually and maybe really hot data (e.g. If you need it to be more aggressive you can change the mode to performance, Your email address will not be published. Regions are a narrow stripe of capacity across many chunklets and are assigned to … 3PAR OS includes the data movement engine, however it has to be unlocked either using Dynamic or Adaptive Optimization. dsstao Jan 28, 2014 8:00 AM ( in response to Arun Pandey ) Nope, nothing else accessing it. Tuesday Night – Move to SAS tier Your email address will not be published. Adaptive Optimization (AO) is 3PAR’s disk tiering technology, which automatically moves the hottest most frequently accessed blocks to the fastest disks and at the same time moves the infrequently accessed cold blocks of data to slower disks. Conversely, if a CPG is already in an AO configuration, then it is not possible to create a compressed volume in the CPG. The new family 8000 will be shipped with the same fifth-generation ASIC that were introduced in the 20000 series arrays earlier this year. Hi, HPE 3PAR Online Import. to take advantage of HP 3PAR StoreServ’s unique features such as vSphere integration, HP 3PAR Thin Provisioning technologies, Dynamic and Adaptive Optimization, Priority Optimization, and HP 3PAR Recovery Manager for VMware to HPE 3PAR Virtual Lock.

Each storage volume resides on a single tier, but maintains mobility between tiers throughout the application lifecycle. Thank you, The data will stay where it has already been moved to, as long as you are aware of this there is no harm in deleting an AO config. If the pattern is truly random like in your example then a different approach would have to be sought. Dynamic optimization is when you manually choose to move an entire virtual volume between tiers. Explain how space is distributed in HP 3PAR storage arrays Configure, interpret and handle HP 3PAR alerts and notifications Size Adaptive Optimization and work with AO reports Prerequisites: Students must have attended HK902 and HK904 and should have managing a 3PAR array for at least 12 months. Making tech simple – 3PAR, Storage, Virtualization and Cloud. This is when of the great 3PAR StoreServ features, allowing ‘regions’ of data to be moved between different storage tiers. Adaptive Optimization operates on the principle of I/O access density, which is the Create Adaptive Optimization Policy Mode– how “aggressive” the policy is. HPE 3PAR Virtual Service Processor (Not included in HPE 3PAR StoreServ 20000) HPE 3PAR Recovery Manager Central Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. The setup for which is a bit more involved than the typical 3PAR deployment. 7. HP 3PAR Adaptive Optimization (AO) enables autonomic storage tiering on HP 3PAR storage arrays. by Philip Sellers July 7, 2014. written by Philip Sellers July 7, 2014. Then perhaps another DO job to move it back to the CPG with AO, once the workload drops. Sunday – Nothing In this short case study, we demonstrate how you can optimize your HPE 3PAR system. Thursday – Nothing Learn about 3PAR StoreServ, AI-powered to deliver enterprise class, Tier-1 all-flash array data storage solutions that provide unmatched agility and efficiency. HPE 3PAR Host Explorer. 3. We have SSD, FC and NL with AO configured. The HP 3PAR Adaptive Optimization Software is a granular, policy-driven, autonomic storage tiering solution that delivers service level optimization for virtual and cloud data centers to reduce cost while increasing agility and minimizing risk. Know that for using this feature you will need the Advanced Data Services license and […] Cheers. If that’s the case you’d always be playing catchup and probably burn more I/O moving data than you’d gain using tiering. One of the nice features of the new StoreVirtual 3200 system is the support for performance tiering to SSD. Regional IO density is measured in terms of IOPs per GB per minute. In this case we will look at how the workload is distributed on the back-end drives and how that relates to the Adaptive Optimization Policies. After my latest post for 3PAR 8000 series, here are more details about the new family. I use 3PAR10800 and I have two types SSD (32 disk SSD 100GB, 32 disk SSD 500GB). Flexible and scalable HP 3PAR StoreServ configuration for SAP by configuring up to eight HP 3PAR controller nodes in combination with nearly 2000 disk drives Built -in dynamic and adaptive optimization features moving SAP data between RAID levels or the storage tiers of By allowing AO complete control of your top tier and not provisioning any volumes from it you can allow AO to take capacity utilisation up to 100%. Tier 1: 3TB RAID1 15K disks Achieving Balance in HPE 3PAR Environments. Saturday – Nothing As of HPE 3PAR OS 3.2.1, the clone can be exported immediately after creation while the data copy continues in the background. The traditional days of storage and having to calculate the number disks and RAID type to allocate to a LUN are gone. 5. technologies, Dynamic and Adaptive Optimization, and Recovery Manager for VMware to create a world class virtualized IT and application infrastructure. Last edited by abelliot on Mon Jan 28, 2019 9:54 am, edited 1 time in total. HP 3PAR, using Adaptive Optimization ATS software (High-end Tier 1.5 array) IBM Storwize v7000, using Easy Tier ATS software (High-end Tier 1.5 array) *Note: Both EMC VMAXe and HDS VSP low end configurations are positioned in the high end of Tier 1.5. Once you have setup your AO config you then need to schedule a task to run AO. As discussed in the timing section if you have applications with very specific access patterns at different times of the day you may need to create multiple policies to correctly analyse this. This point effectively summarises all those above. The goal of the class is to acquaint the 3PAR administrator with additional topics and features of the HPE 3PAR array. The HPE 3PAR Adaptive Optimization Software is a granular, policy-driven, autonomic storage tiering solution that delivers service level optimization for virtual and cloud data centers to reduce cost while increasing agility and minimizing risk. Once a region has been marked as a candidate for movement the systems then performs a number of sanity checks, to verify if the region move should go ahead: To understand AO design we next need to consider what the building blocks of an AO setup are. Peer Persistence and Adaptive Optimization interoperation on 3PAR. An example of AO config is shown in the table below. Friday – Nothing HPE 3PAR File Persona. Regions are a narrow stripe of capacity across many chunklets and are assigned to … Initial binding was done from NL as it has the most capacity comparing to others. Cables. The goal of the . I’ve recently noticed that this configuration has, SSD_r1/FC_r1/NL_r6 as it’s CPGs. What about Remote copy can you run AO on this VV? As long as nothing is directly provisioned from the SSD tier, you can let AO take the utilisation right up to these high levels. Just because a system is perceived as having a higher importance by the business does not mean that it has a higher regional access density. From a software perspective both products implement ATS identically to their Tier 1 brethren. This is part one of a two part series on enhancements to the HP 3PAR StoreServ platform announced at HP Discover in June. It is not available on the all flash models for obvious reasons. Any idea how I can make the array view both sizes of SSD as 1 big pool and use accordingly, they are both 150k and the SSD cpg is set to default speed? Adaptive Optimization this is the automated movement of 'regions' of data based on policies. 3PAR + HPE consultancy and hardware – Contact, Never miss the latest 3PAR tips and tricks, Regular 3PAR tips, tricks and news direct to your inbox, Adaptive Optimization Design Considerations. Hi all, new to 3par with a question with regarding Adaptive Optimization configuration. AO does its voodoo by analysing the number of hits a region gets within a time period to measure its regional IO density. Are they in one CPG? Isn’t what your asking for called cache ? In an AO config you define your tiers of disk through the selection of CPG’s and then choose an operational mode optimised for cost, performance or a balance between the two. Would I instead have to create a new volume with a new AO config as I want it and then move the date from one volume to another? I supended AO. This way any new writes aren’t hitting slow disk, but also aren’t taking up valuable space in your top tier. The information contained in this document should be used along with the documentation set provided by HP for the HP 3PAR StoreServ Storage system, HP 3PAR Operating System, and the documentation HPE calls this, similar to 3PAR, Adaptive Optimization. Size Adaptive Optimization and work with AO reports Interpret different HP 3PAR performance metrics and how the array's features can affect performance Tune and rebalance HP 3PAR storage arrays The HP Converged Storage philosophy makes this feature now also available on the StoreVirtual platform. All CPG’s in an AO config should be set to use the same availability level, for example cage. Could you please explain how Dynamic Adaptive optimization works ? You can have between two and three tiers, 0 being the fastest and 2 being the slowest. I’m wondering whether this is possible and whether there are any issues to doing so as all the recommendations I’ve read so far (including the above) seem to suggest that provisioning should always happen from the middle tier in a 3 tier system (which is not possible in my case). So you may expect to see all your VV’s (Virtual Volumes) that are demanding the most IOPs end up in your tier 0 SSD’s, this however is not the case as AO is a sub-lun tiering system, i.e. Although the AO config is not replicated, so you may find if you fail over to another site it would take a while for AO to optimise the layout of the regions. If a compressed volume exists within a common provisioning group (CPG), then the CPG i s not available for use in an AO configuration. So if you do go down the route of having multiple AO policies you must have a separate CPG to represent each tier of disks in each different AO policy. Adaptive optimization builds upon 3PAR’s existing chunklets, dynamic optimization, regions and wide striping technologies. In this case we will look at how the workload is distributed on the back-end drives and how that relates to the Adaptive Optimization Policies. So now we understand AO is a tiering technology that intelligently places our data based on how hot (frequently accessed) or cold it is. I would suggest selecting balanced to start with then monitoring and adjusting accordingly. I made this change for a customer recently moving from an AO config that only allowed business critical apps access to the SSDs, to allowing all data to move freely across all tiers. In this article I will describe the process how to enable Adaptive Optimization. I have’t allocated anything from SSD, it is purely for AO. For AO to be a good fit the regional IO density needs to be high i.e. Monday Night – Move to SSD tier As of HPE 3PAR OS 3.2.1, the clone can be exported immediately after creation while the data copy continues in the background. web caches) in Tier 0. Hi, HP 3PAR Adaptive Optimization Software Solution brief HP 3PAR® Adaptive Optimization Software is a granular, policy-driven, autonomic storage tiering software solution that delivers service level optimization for enterprises and cloud data centers to reduce cost … or we will set AO configuration during the CPG creation time ? Remember space in your higher tiers is at a premium, by second guessing and placing the wrong data in your tier 0 you are short changing yourself. If you want to take advantage of deduplication with thinly deduplicated virtual volumes you will need to place the volumes directly on the SSDs and they cannot be on a CPG which is part of an AO config. As ever feel free to share your perspective and experiences on AO design in the comments sections and on Twitter. Good explanation. Tag Archives: 3PAR Adaptive Optimization More details for 3PAR 8000 series. a high proportion of your IOPs comes from a small proportion of capacity and the workload must have some kind of repeatable pattern to it. Adaptive Optimization Conversion NOTE: This section applies only to HP 3PAR OS HP 3PAR OS 3.1.2. Patrick Terlisten blog post – Some thoughts about HP 3PAR Adaptive Optimization, HP 3PAR StoreServ Storage best practices guide, HP Technical white paper Adaptive – Optimization for HP 3PAR StoreServ Storage. DO NOT set a CPG space limit though this is a hard stop and will stop any data being written. Re: Unmanaged I/O Workload Detected - 3Par Adaptive Optimization? • The minimum size of a compressed volume is 16 GiB. HPE 3PAR Virtual Domains. On the systems screen It shows the SSD as 2 different entries and massively favours the original smaller disk, in fact, when I select an SSD cpg it shows only a small amount of available space left when I know the newer SSD has loads of space. I was mostly thinking about something that would fit completely into SSD, which would imply a small amount of data. 4. Flexible and scalable HP 3PAR StoreServ configuration for SAP by configuring up to eight HP 3PAR controller nodes in combination with nearly 2000 disk drives Built -in dynamic and adaptive optimization features moving SAP data between RAID levels or the storage tiers of Interesting question Jason. How do you know if your 3PAR’s Adaptive Optimization (AO) is optimized? If you find you have certain servers with very specific access patterns adjust the timing to monitor during these periods. For a reminder on what CPGs are about go here. An AO config can consist of between two or three layers of disk. Frequently accessed regions of volumes are moved to higher tiers, less frequently accessed regions are shifted to lower tiers. This is actually the point that inspired me to write the post and I believe is the most important design principle, keep it simple. Tier 2: 14TB RAID5 10K disks. Although it is possible, do notcreate 2 tier AO policy between NL and SSD disk as the speed difference is substantial and will impact response time on the workloads. 8. I create CPG on 64 disk SSD and schdule AO 2 tier SSD and FC. But I would free space or buy more disks ASAP to resolve this issue. Chunklets are little, virtual pieces of physical disk. To give an example if you have a 100GB VV and only 2 regions are getting hit hard only 256MB of data need to be migrated to SSD, a massive saving in space compared to moving the entire volume. Craig thanks for reading and commenting. There will always be exceptions to simplicity, but at least give simplicity a chance and then tune from there. You need to create LUNs in CPG defined in tier 1. Some example tiers would be: Even if you do start with a two tier system without SSDs, leave tier 0 empty in your config so that you can add SSDs at a later date. Adaptive & Dynamics Optimization. Peer Persistence and Adaptive Optimization interoperation on 3PAR. My question is whether what I want is do-able and whether there are any catches? Don’t try and second guess where data would be best placed, the machine will outsmart you. You can also now filter by volume, so you can have different schedules for specific VV’s within the same CPG and config. It would be good if HP could learn the storage characteristic and then adapt for a time period for example lets say you had a workload that ran weekly which was IO intensive. Are there negative affects to this? Tuesday – Normal Workload Of course while it was migrating there would be some impact on performance. In March 2010, the company introduced 3PAR Adaptive Optimization, the industry's first implementation of autonomic storage tiering for cost optimization in high-end storage systems, targeted at enterprises and service providers. Yes can change an AO configuration at any time, Hi Richard, each Monday is an intensive day you could create a schedule which looked at the appropriate period from the previous week, although this would start to take you away from the model of simplicity. H‰\”Í�›@„ïw+~g$ Ûkɇü(Ş. If we’ve determined that we don’t need to run AO, (however, a previous admin created an AO configuration) can this existing AO configuration be deleted? You can set a max runtime on AO to make sure that it is not running during business hours. We have 3 CPG’s(SSD/FC/NLSAS). As NL disks are often used in tier 2 many companies cannot tolerate the hit of new writes initially going to slow disk. The HPE 3PAR Adaptive Optimization Software is a granular, policy-driven, autonomic storage tiering solution that delivers service level optimization for virtual and cloud data centers to reduce cost while increasing agility and minimizing risk. Re: Unmanaged I/O Workload Detected - 3Par Adaptive Optimization? The setup for which is a bit more involved than the typical 3PAR deployment. AO is controlled through an AO config. I've found in one document with following statement: "Adaptive Optimization (AO) supports RC but until failover, the AO policies on the destination array should remain disabled. For instance, HPE Primera will not include the Adaptive Optimization technology that 3PAR uses to tier data between hard disk drives and more expensive solid-state drives. View Adaptive Optimization for HPE 3PAR.pdf from AA 1Adaptive Optimization for HPE 3PAR StoreServ Storage Hybrid storage on HPE 3PAR StoreServ Technical white paper Technical white This granular level of analysis and movement ensures that the capacity of expensive SSD disks is utilised to its fullest, by moving only the very hottest regions as opposed to entire VVs. The key design principle here is to keep drives and drive cages balanced across nodes so performance in turn remains balanced. But I think there would be a couple of challenges with this approach. Each storage volume resides on a single tier, but maintains mobility between tiers throughout the application lifecycle. HP 3PAR Dynamic Optimization Software non-disruptively alters service levels of a volume with a single click, without scheduling, planning, or impacting application performance. >Îz¬†µ£¦\$: h(30%¨0€mf°e€ˆğ30°_àwPıÀÀ Ü Æø�)„ãK…ˆƒi£²cJÓWö)| Ì

’ I’ve got no problem with the lun initially being a little slow and then gradually improving over time (as stuff moves up the tiers). HPE 3PAR Adaptive Optimization. And HP do have adaptive flash cache. It is intelligent enough to not move more blocks than there is space available. Adaptive optimization builds upon 3PAR’s existing chunklets, dynamic optimization, regions and wide striping technologies.
