Existing data on the CPG will remain in the old format. 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. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. This is part one of a two part series on enhancements to the HP 3PAR StoreServ platform announced at HP Discover in June. You need to create LUNs in CPG defined in tier 1. Dynamic optimization is when you manually choose to move an entire virtual volume between tiers. HPE 3PAR Priority Optimization. With this feature the HP 3PAR storage system analyzes IO and then migrates regions of 128 MB between different storage tiers. 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. When you create a new VV do so from your middle tier if you are using a 3 tier config. Not so much. HPE 3PAR Host Explorer. When you hit this level AO will not move any more data to those disks. or we will set AO configuration during the CPG creation time ? One of the nice features of the new StoreVirtual 3200 system is the support for performance tiering to SSD. • The minimum size of a compressed volume is 16 GiB. There will always be exceptions to simplicity, but at least give simplicity a chance and then tune from there. The Managing HPE 3PAR StoreServ II course is designed for the experienced HPE 3PAR administrator. I 'll plan to delete it. I have a customer requirement to pindown a vv to SSD CPG. Are you using any filters on CPG? 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. I would like to create an AO with a somewhat non usual config for my VMs: HPE 3PAR Host Explorer. 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%. 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. I supended AO. Re: Unmanaged I/O Workload Detected - 3Par Adaptive Optimization? Peer Persistence and Adaptive Optimization interoperation on 3PAR. Tuesday – Normal Workload HPE calls this, similar to 3PAR, Adaptive Optimization. Here, does the R1 mean R1+0? 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. Adaptive Optimization this is the automated movement of 'regions' of data based on policies. I think the other feature you are looking for is Adaptive Optimizer and sub-volume tiering... policies are defined within "System Reporter", which runs on a separate server in your environment and accessed via web browser. DO NOT set a CPG space limit though this is a hard stop and will stop any data being written. HPE 3PAR Adaptive Optimization (AO). Peer Persistence and Adaptive Optimization interoperation on 3PAR. We know Adaptive Optimization already from the StoreServ 3PAR platform. This site uses Akismet to reduce spam. Friday – Nothing HPE 3PAR Adaptive Optimization. 4. You can try to get all data laid out in the new RAID style by running a tunesys afterwards. You need to be aware that AO only occurs across a node pair. Re: Unmanaged I/O Workload Detected - 3Par Adaptive Optimization? 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. AO does its voodoo by analysing the number of hits a region gets within a time period to measure its regional IO density. HPE 3PAR 8400:- Can we limit AO with 1TB or 2TB to be occupied in Tier 0? You can also now filter by volume, so you can have different schedules for specific VV’s within the same CPG and config. Then when its the original CPG is empty you would be able to delete it. A CPG can only exist within one AO config. If you do run multiple AO policies set them to start at the same time, this will minimise the chance of you running into space problems, The three AO modes are quite self-explanatory, at either extreme performance moves data up to higher tiers more aggressively, cost – moves data to cheaper large capacity tiers more aggressively, balanced is a half-way house between the two. If you are from an EMC background AO is comparable to FAST VP, if you are from a NetApp background welcome to the brave new world of tiering. 10. Regions are a narrow stripe of capacity across many chunklets and are assigned to … AO is controlled through an AO config. Conversely if you choose to lock a VV into a lower tier of CPG on NL disks it may become busy and have nowhere to move up to, hammering the disks it’s placed on and affecting all the volumes hosted from there. Once you have setup your AO config you then need to schedule a task to run AO. 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. Audio/Video Cables; Ethernet Cables; Network Cables The minimum amount of Flash Cache that can be specified on an HPE 3PAR StoreServ array regardless of model is 64 GB per node pair. My question is whether what I want is do-able and whether there are any catches? Performance – more data moved to higher tier Balanced – balance in between Cost– more data is moved to lower tier Notes All your writes will be going to Tier 1. 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 Adaptive optimization builds upon 3PAR’s existing chunklets, dynamic optimization, regions and wide striping technologies. Are there negative affects to this? Hardware Software Brands Solutions Explore SHI Tools . 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. This white paper takes you through an HPE 3PAR Adaptive Optimization Case Study to demonstrate how the AO functions so that you can optimize your HPE 3PAR environment. 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? One of the nice features of the new StoreVirtual 3200 system is the support for performance tiering to SSD. | HPE New Zealand You can create 2 tier AO between FC and SSD or FC an… Thanks, Yes you can limit the space AO uses by setting a Space Warning on the SSD CPG. • The minimum size of a compressed volume is 16 GiB. Aug28. Last edited by abelliot on Mon Jan 28, 2019 9:54 am, edited 1 time in total. I 'll plan to delete it. And HP do have adaptive flash cache. If a compressed volume exists within a common provisioning group (CPG), then the CPG i s not available for use in an AO configuration. But I think there would be a couple of challenges with this approach. This is part one of a two part series on enhancements to the HP 3PAR StoreServ platform announced at HP Discover in June. In this short case study, we demonstrate how you can optimize your HPE 3PAR system. After my latest post for 3PAR 8000 series, here are more details about the new family. How aggressive AO is in moving data is dependent on the performance mode selected. After my latest post for 3PAR 8000 series, here are more details about the new family. technologies, Dynamic and Adaptive Optimization, and Recovery Manager for VMware to create a world class virtualized IT and application infrastructure. Don’t try and second guess where data would be best placed, the machine will outsmart you. Adaptive Optimization Conversion NOTE: This section applies only to HP 3PAR OS HP 3PAR OS 3.1.2. As ever feel free to share your perspective and experiences on AO design in the comments sections and on Twitter. It is not available on the all flash models for obvious reasons. HPE calls this, similar to 3PAR, Adaptive Optimization. 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? can we do the AO confugration on existing CPG ? 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. 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. HPE 3PAR Adaptive Optimization. For a reminder on what CPGs are about go here. Additional CPG’s create additional management overhead in terms of reporting etc. Which one you choose will depend on if your aim leans towards achieving optimum cost or performance. From a software perspective both products implement ATS identically to their Tier 1 brethren. I’m sure the boffin’s at HP could track and analyse this so that AO became predictive. Now I am very worry disk SSD 100GB alocate 98%. AO is a licenced feature that is enabled through the creatively named Adaptive Optimization software option and is available across all the hybrid models. Chunklets are little, virtual pieces of physical disk. 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. I have very few space left in SSDs and also VVs are TDVVs. HPE 3PAR System Reporter. If the pattern is truly random like in your example then a different approach would have to be sought. 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. 3PAR OS includes the data movement engine, however it has to be unlocked either using Dynamic or Adaptive Optimization. Last edited by abelliot on Mon Jan 28, 2019 9:54 am, edited 1 time in total. HPE 3PAR Adaptive Optimization (AO). I use 3PAR10800 and I have two types SSD (32 disk SSD 100GB, 32 disk SSD 500GB). >Îz¬†µ£¦\$: h(30%¨0€mf°e€ˆğ30°_àwPıÀÀ Ü Æø�)„ãK…ˆƒi£²cJÓWö)| Ì
’ Thursday – Nothing ... Work with Adaptive Optimization to implement virtual volume tiering to save storage costs • Work with Priority Optimization to prioritize higher priority workloads over lower priority Monday – Intensive Workload Hi, AO occurs on a schedule you cannot force it. Start again by keeping things simple, monitor during your core business hours and be careful to not include things like backups in your monitoring period which could throw the results off. This seems ‘understandable’ to me in that I expect most of the data to move down to Tier 2 (e.g. The new family 8000 will be shipped with the same fifth-generation ASIC that were introduced in the 20000 series arrays earlier this year. So on a 7400 with 4 nodes, AO would occur across the cages attached to nodes 0, 1 and across those attached to nodes 2, 3. 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. Learn about 3PAR StoreServ, AI-powered to deliver enterprise class, Tier-1 all-flash array data storage solutions that provide unmatched agility and efficiency. note: 3par_as49_datastore and 3par_optilogistic_datastore is not used. Tier 0: 1TB RAID5 SSD Create a new CPG on SSD, don’t add to AO then use Dynamic Optimization to migrate the VV to the new CPG. Adaptive & Dynamics Optimization. Learn how your comment data is processed. Beyond the flashy features, many 3PAR customers will find that Primera will not support some of their favorite capabilities. I would suggest selecting balanced to start with then monitoring and adjusting accordingly. Is there a possibility to prioritize the data movement? Are they in one CPG? Secondly remember AO works on regional IO density and so is able to move just the hottest regions to your smaller more expensive high performance tiers. Now the NL utilization is 99% , could you confirm if there is any impact?i mean like the VV’s goes to RO as there is no capacity or It will move the data to other tiers?Also I could see the data movement is not happening as like FAST. Timing is a key consideration. Hi, Does anyone know how 3PAR's Adaptive Optimization treats VMware VVOL's. Tier 2: 14TB RAID5 10K disks. 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. technologies, Dynamic and Adaptive Optimization, and Recovery Manager for VMware to create a world class virtualized IT and application infrastructure. We have 3 CPG’s(SSD/FC/NLSAS). 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. However If you try to force movement based on your own bias, rather than the arrays recorded heuristics then you’ll likely be disappointed , Jim welcome to the blog and thanks for the comments. Each storage volume resides on a single tier, but maintains mobility between tiers throughout the application lifecycle. If for example you choose what you believe are your busiest VV’s and lock them to an SSD CPG you may find only a small proportion of data is hot, and be robbing yourself of space. AO is enabled and is in Performance Mode.Currently this vv is in all the 3 tier’s as per the AO calculation. Aug28. H‰\”Í�›@„ïw+~g$ ÛkÉ‡ü(Ş. BTW there’s a min IOps setting to prevent demotion due to minimal access. First of all DO operations take time, so if it was a larger volume you could be waiting several days for it to migrate to SSD’s and then several days back again. At first make the max run period as long as you can outside of business hours to give AO every opportunity to run. 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. At least start out with a single AO policy containing ALL your tiers of disk and allow ALL data to move freely. Adaptive & Dynamics Optimization This is when of the great 3PAR StoreServ features, allowing 'regions' of data to be moved between different storage tiers. We have SSD, FC and NL with AO configured. I would however say it would be cleaner to create a new CPG, and then to use dynamic optimization to move the volumes over. HPE 3PAR File Persona. I have couple 3par 7400(source and destination using remote copy) with AO configured using SSD, FC and NL as my tiers. Below the different tiers of disk are shown diagrammatically along with some example of blocks of data tiering both up and down. An example of AO config is shown in the table below. by Philip Sellers July 7, 2014. written by Philip Sellers July 7, 2014. The traditional days of storage and having to calculate the number disks and RAID type to allocate to a LUN are gone. The new family 8000 will be shipped with the same fifth-generation ASIC that were introduced in the 20000 series arrays earlier this year. I create CPG on 64 disk SSD and schdule AO 2 tier SSD and FC. 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 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. Hi, I have a 3 tier AO config. OS footprint, installed programs etc) with some data going to Tier 1 eventually and maybe really hot data (e.g. 888-764-8888 . The net result was utilisation of each SSD increased from 200 to 1000+ IOPs each, thus reducing the pressure on the lower tiers of disks. 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. The Managing HPE 3PAR StoreServ II course is designed for the experienced HPE 3PAR administrator. Now that that we understand the principles and the building blocks of AO, let’s look at some of the design considerations. You can think of this as being a gold, silver and bronze level in terms of performance. 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. Hi all, new to 3par with a question with regarding Adaptive Optimization configuration. If a compressed volume exists within a common provisioning group (CPG), then the CPG i s not available for use in an AO configuration. HPE 3PAR Virtual Service Processor (Not included in HPE 3PAR StoreServ 20000) HPE 3PAR Recovery Manager Central Wednesday – Nothing 6. 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. 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 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. 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 After running happily for a while I added further SSD disk into my P1000 array which is of a larger size to the original SSD. Cables. As long as nothing is directly provisioned from the SSD tier, you can let AO take the utilisation right up to these high levels. The inclusion of HP 3PAR Adaptive Optimization software in this suite helps deliver an increase in IOPS and reduced latency at a lower storage cost than traditional storage. The setup for which is a bit more involved than the typical 3PAR deployment. I have’t allocated anything from SSD, it is purely for AO. Adaptive & Dynamics Optimization This is when of the great 3PAR StoreServ features, allowing 'regions' of data to be moved between different storage tiers. As with most things in life its best kept simple. This point effectively summarises all those above. Beyond the flashy features, many 3PAR customers will find that Primera will not support some of their favorite capabilities. The advice not to provision from tier 2 relates is because any new writes will initially hit this tier and then have to wait till AO kicks in for any hot data to be tiered up. Tier 1: 3TB RAID1 15K disks In this short case study, we demonstrate how you can optimize your HPE 3PAR system. We’ve got several volumes now using this config. In summary there is no technical reason not to do this, it’s just if you can accept the slower speed from new writes to 10K disks. Could you please explain how Dynamic Adaptive optimization works ? 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 3PAR OS includes the data movement engine, however it has to be unlocked either using Dynamic or Adaptive Optimization. 8. 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. Monday – On wrong tier. As NL disks are often used in tier 2 many companies cannot tolerate the hit of new writes initially going to slow disk. But I would free space or buy more disks ASAP to resolve this issue. 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. For AO to be a good fit the regional IO density needs to be high i.e. 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. HPE 3PAR Virtual Service Processor (Not included in HPE 3PAR StoreServ 20000) HPE 3PAR Recovery Manager Central 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. 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. Tuesday Night – Move to SAS tier If you change the RAID settings on an existing CPG this will just impact new writes to that tier. My concern with AO is that it’s reactive and not real time. If you find you have certain servers with very specific access patterns adjust the timing to monitor during these periods. 3PAR Adaptive Optimization and VMware VVOL's. HPE 3PAR Virtual Domains. 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 … Create Adaptive Optimization Policy Mode– how “aggressive” the policy is. Just provision your VVs from the CPG representing the central tier, allow the volumes access to all the disks and let the system decide which RAID and disk type is appropriate at a sub-lun level. The goal of the . So now we understand AO is a tiering technology that intelligently places our data based on how hot (frequently accessed) or cold it is.
