3 Abstract This white paper provides a brief introduction to the IBM System Storage SAN Volume Controller (SVC) cluster with the IBM Easy Tier feature in the release. The paper gives information regarding the Easy Tier configuration, management, and upgrade changes in detail. This paper also provides guidance about configuring the Easy Tier feature in the SVC cluster. It also describes the Easy Tier licensing changes in the release compared to the release, along with the upgrade considerations. Getting started This section gives a brief idea about the basics of the IBM Easy Tier feature along with the implementation details. Introduction to Easy Tier IBM Easy Tier feature is supported with IBM System Storage SAN Volume Controller (SVC), IBM Storwize V7000, IBM Storwize V7000 Unified, IBM Storwize V5000, IBM Storwize V3700, and IBM System Storage DS8000. This paper describes the functionality in SVC and Storwize products that are specific to release IBM Easy Tier is designed to automate data placement throughout the disk pool to improve the efficiency and performance of the storage system. Easy Tier aims to relocate data (at the extent level) across up to three-drive tiers automatically and without disruption to application I/O. These operations are transparent to users and completely handled by the SVC code. This helps users to have the most frequently used data or hot data accessible very fast and with lower latency, whereas the archaic data will be stored in a relatively lower medium of storage. Easy Tier detects when any data extent is heavily in use and moves to a higher tier of storage. As a result, data is available very fast, without having to shed huge costs. The key benefit of Easy Tier in to older versions is that it allows tiering between three tiers. This increases the performance of the system. It supports data movement across three tiers, and therefore, the data can be classified in to following three categories based on usage, Heavily used data (also called hot data) Moderately used data (also called warm data) Cold data Easy Tier stores hot data in the fastest type of disk, that is, on solid-state drives (SSDs) and warm data and cold data are stored in enterprise disks and nearline SAS disks respectively. Easy Tier algorithm works in such a way that it always puts heavily used data in the upper storage tier. User transparency The Easy Tier feature is completely transparent to the users and manages all data movement without any explicit user intervention. Data across tier is being migrated when a certain condition is arrived. This condition checking is automated in this feature. Users can see the extent of movement by cluster CLI commands such as lsvdiskextent. Some of the transparency details include: 1
4 Moving of inactive data automatically on cheaper storage instead of high-cost SSDs can save data retrieval time. This also saves the costumers money to buy additional SSDs. When active hot data is moved from an enterprise disk to an SSD, the user can notice a significant decrease in latency. Previously, when only two tiers were supported, there was either fast accessibility or slow accessibility. But with the introduction of the third tier and dividing the generic_hdd tier into enterprise and nearline, it is possible to achieve better performance even when the tier is not SSD disks in the system. Easy Tier supports the load or performance rebalancing feature. Hence from a user's perspective, latency has been minimized to a substantial level. For inactive cold data, which is not used often and are mainly for archival purposes, there is no need to store such data in costly, high-performance SSDs. Instead, it moved to a cheaper medium: such as nearline, and whenever the data gets hot, it is automatically moved to a better layer. Migration of extents With the extension of support for three tiers, migration attempts to preserve the tier of an extent after user initiated migration, that is, if an extent is created from a managed disk (MDisk) of enterprise type, then after migration, it attempts to preserve the tier of the extent, that is, it will seek to conserve it as an enterprise tier. If an extent of the correct type is not available in the target pool, then it searches for a free extent from the other tiers in the order: enterprise, nearline, SSD. This is the same order in which creation and expansion will select extents from MDisks. However, it is possible to override the tier explicitly by specifying the appropriate MDisks using the -mdisk option. During user-initiated migration, Easy Tier management (including balancing function) will be disabled. Easy Tier measurement continues during migrations if Easy Tier was enabled before the migration started and will be enabled after the migration completes. In Easy Tier function of release, there are basically two types of migration based on tier levels: Intra-tier migration: The extent migration between the same tier disks is nothing but intra-tier migration. This type of load balancing is also known as balancing. If a system has some highly utilized disks and some low-utilized disks, then some hot extents from the highly utilized disks are moved to the underloaded disks. Here, both the disks are of the same tier. Inter-tier migration: The extent migration across the tier is also known as inter-tier migration. In this type of migration, the extent of one tier moves to the other tier disk. This migration can happen if the destination MDisk is the upper tier MDisk and has no performance downgrade after the migration and another MDisk of lower tier has hot data. This migration can also be called as the extent promote operation. If the upper tier MDisk has cold data, then this cold data is migrated to the lower tier disk, provided, the destination has the capacity to accommodate the extent completely. This cold data migration to lower tier disk is also known as the cold demote operation. Another scenario can be if the extents on the MDisks are extremely hot and hitting the performance limit of the MDisk; then the extents are demoted to a lower tier in order to protect the higher tier performance. This is known as the warm demote operation. 2
5 What is new in release There are mainly four new functions introduced in Easy Tier release Limiting function This is a new function that handles performance monitoring and denies extent to migrate if the destination disk is already overloaded or gets overloaded after extent migration. Balancing This function deals with extent migration within the same tier MDisks. This function is out of Easy Tier licensing. Support for three tiers Older Easy Tier supports two technology types, that is, SSD and hard disk drive (HDD) which are considered as Tier0 and Tier1 respectively. Easy Tier of release cares about SSD, enterprise, and nearline. The generic_hdd tier is split into enterprise and nearline tier. Therefore the "tier" can have the values "ssd, enterprise, nearline". Licensing changes Significant changes have happened in Easy Tier licensing in the release. These changes are explained briefly in the following subsections. Limiting function Although SSDs have grown in size, they have not grown the same in performance. SSDs can have nasty characteristics when overloaded; the performance might degrade significantly and abruptly when the SSD reaches its load capacity. Easy Tier code implementation in versions before release has nothing to prevent it from putting too many extents on SSD. Due to this SSD s performance could actually become worse. In Easy Tier release, the limiting function is introduced. This limiting function takes care of the SSD s performance and limits the extent migration to SSD when it reaches to performance limit. This function helps to control extent movement in case of nasty behavior of SSD disks. Also, in case of external MDisks, Easy Tier collects statistics about the utilization of MDisk. It calculates the controller performance value and displays through lsmdisk CLI (detailed view only). These values are sampled into low, medium, high, very_high and blank for array MDisks. The user can change the controller performance value using the chmdisk command. The valid values can be default, low, med, high, and very high. Choosing "default" causes the value to revert to the system determined value. The "very_high" parameter to this command will only be valid if the tier is "ssd". If the controller performance is "very_high" and the user changes the tier from "ssd" to "enterprise" or "nearline", the controller performance value will automatically be changed to "high" (while converse is not true). This functionality is not supported by cluster GUI. Balancing function Balancing is a feature that deals with extent migration within the same storage tier. The extent migration between the same tier MDisks are nothing but intra-tier migration. If a disk is highly utilized (and the other disks of the same tier than that first are low utilized) then some hot extents are moved to the low-utilized disk if the low-utilized disk does not reach the performance limit after the migration. Here, both the disks are of same tier. This feature of balancing is available in all types of tiers and is out of the purview of Easy Tier licensing. The balancing function improves performance as hotter extents are distributed among 3
6 multiple disks of the same tier. This function plays an important role in overloading scenarios, where extent migration improves performance by great extent. Versions before release require a balancing script to balance the extents across MDisks. By rebalancing the extents from existing volumes onto new MDisks, existing volumes will get a performance boost. This balancing script is not required from release as the balancing function is invoked immediately after the addition of an MDisk in an MDisk group.. IBM System Storage SVC supports balance capability for single-tier pools. The auto balancing function will be on by default in SVC/Storwize. As most customers prefer to keep management and customer decision making to a minimum, the best option is to just have that as the default. Support for three tiers Versions before Easy Tier release supports two technology types: SSD and HDD which are considered as Tier0 and Tier1 respectively. While assigning a value to tier, user can pick from a technology type (generic_ssd, generic_hdd). In Easy Tier until release 7.2.0, this value of tier is used for internal computation. This limitation in earlier versions has been overcome in Easy Tier release. In the release of SVC, Easy Tier cares about SSD, enterprise, and nearline, and therefore, the "tier" can have the values "ssd, enterprise, nearline". "generic_hdd" in Easy Tier is changed to "enterprise" with the addition of "nearline". Lowest technology types (such as SSD, enterprise, or nearline) are used if an MDisk is made from mixed disks rather than what user assigns or overrides. Easy Tier has multitier support with two independent modes of action: Promotion and demotion (either can cause a swap.) Promotion moves an extent up by 1 tier while demotion moves an extent down by one tier. Easy Tier code does not cope up with moving an extent from tier 2 to tier 0 (or from tier 0 to tier 2) in one go. But, if you have a pool of technology types (such as SSD and nearline) then SSD arrays are mapped to tier 0 and nearline arrays are mapped to tier 1. Due to this, a two-tier promotion/demotion is avoided. Easy Tier licensing changes Easy Tier is a feature that requires a distinct license. The licensing is different for each product type. The following license restrictions are applicable for various Storwize products. SVC and Storwize V7000 do not require a license for Easy Tier Storwize V3500 does not allow Easy Tier Storwize V3700 requires a license and it is strictly enforced. Setting Easy Tier to on has no impact if Easy Tier is not licensed and when the user acquires a license, Easy Tier becomes active. With Storwize V5000, the user is supposed to purchase a license for Easy Tier, but it is not enforced. Instead, warning messages are produced if the user enables Easy Tier without a license. Therefore, Easy Tier status will not automatically change to on when upgrading to Storwize V5000. If a user acquires an Easy Tier license for Storwize V5000, then Easy Tier status becomes active automatically without any additional user action. This licensing change affects the easy_tier "auto" functionality. The easy_tier auto functionality translates to on if Easy Tier is licensed or no license is required and is off if Easy Tier is not licensed and a license is required. Changing Easy Tier from "auto" to "on" will enable Easy Tier when a license is required but the 4
7 license is not strictly enforced. It will have no effect if a license is required and the license is strictly enforced. Also, changing Easy Tier to "measure" will not have any effect when a license is required and the license is strictly enforced. Thus the "easy_tier" attribute can then take on the values auto, on, off, and measure. Similarly, the "easy_tier_status" attribute undergoes changes with licensing. The status, "active" will now mean that Easy Tier is managing the multitier pools while it is balanced for a single-tier pool. A new value "measured" indicates that Easy Tier statistics are being collected for all vdisks but no management is taking place. The status, "inactive" means that Easy Tier is neither collecting statistics nor managing the tiers. Easy Tier limitation If the Storwize V3700 setup with a 4 GB node memory reaches above 700k extents, then Easy tier functionality gets automatically disabled and error message (storage optimization services disabled) is flagged. This error disappears automatically after the addition of canister RAM or molding setup to less than 700k extents. Customer scenarios This section includes customer scenarios namely upgrade to version and performance benefits. Upgrade section mainly includes CLI changes in upgrade to The other subsections talks about the performance benefits of the Easy Tier functionality of the version. This includes performance benefits of Easy Tier and snaps of performance statistics graphs. Upgrade to version Upgrade is actually fairly simple. While upgrading from older versions to the version, some changes can be observed by custumers. Compatibility has two aspects namely, task commands and list commands. With respect to task commands, code continues to accept prior (now superseded) values and map them to an appropriate value. If the user enters "generic_hdd" on the command line in a situation where it is possible to specify a "tier" value, then that will be accepted and mapped to "enterprise". Similarly "generic_ssd" will map to the ssd tier. With respect to list commands, if the setting of pools (both single tier and multiple tiers) is easy_tier = auto, it remains unchanged, and the status of the pool becomes easy_tier = active (if permitted by licensing), and the volumes' setting remains unchanged, but the status gets updated accordingly. For the volumes in the "auto" single-tier pool, the easy_tier_status will become "balanced", and others remain same. A multitier MDisk group with "easy_tier" of "on" will be unchanged. A pool (consisting of multiple tier and single tier) with "easy_tier" of "off" will be unchanged. For a single tier MDisk group with "easy_tier" of "on", the status will be inactive. If Easy Tier is not licensed, a license is required and it is strictly enforced. An MDisk group whose "easy_tier" attribute is "off" will be unchanged. 5
8 Figure 1: lsmdisk command output in version After upgrading to build, MDisks tier values are changed. generic_ssd becomes ssd, generic_hdd layer is split into enterprise and nearline tiers. Figure 2: lsmdisk command output after upgrade to Version shows below output (Figure 3) after execution of lsmdiskgrp command. Here mdiskgrp 0 is made from all three types of tiers. This command shows easy_tier status along with tier_mdisk_count for each tier in mdiskgrp. 6
9 Figure 3: lsmdiskgrp command detailed view of mdiskgrp 0 in version After upgrading to version, if license is provided to the system or if it is not strictly enforced, then hybrid tier pool s MDisk group parameters that are easy_tier and easy_tier_status remains unaffected If license is not provided in case it is strictly enforced, then the easy_tier parameter will as before upgrade while easy_tier_status will be inactive. In this case, the generic_hdd tier is split into enterprise and nearline tiers and all three tier values are shown as part of the lsmdiskgrp command. 7
10 Figure 4: lsmdiskgrp command output for mdiskgrp 0 after upgrade to version In the case of pool 1 which is made up from two MDisks, one is an enterprise MDisk and another is a nearline MDisk. As versions before Easy Tier has only two tiers, it is showing both as generic_hdd and hence tier_mdisk_count is two. As Easy Tier 1 handles enterprise and nearline disks as generic_hdd, the tier_mdisk_count of this pool is two. 8
11 Figure 5: lsmdiskgrp command a detailed view of mdiskgrp 1 in version After upgrading to version, as three tiers are supported, all the entries of mdiskgrp are recalculated and filled accordingly. Due to this, one pool1 MDisk is recognized as nearline and tier_mdisk_count is recalculated as shown in Figure 6. 9

16 Performance benefits After the Easy Tier feature is activated in the system, customers can see improved performance statistics. This performance benefit is in terms of improved I/O rate and reduction in latency period. As Easy Tier move hot extents to upper tier which has high performance capability, the overall performance of the system increases and the read/write operation becomes faster. Considering a scenario in which a volume is created from a pool of an SSD and a nearline MDisk. In this example, volume extents are on the nearline MDisk and hence all read/write operations are on extents of nearline disks. As Easy Tier is active in the system, it monitors all the I/O operations happening in the pool and migrates hotter extents to the upper tier. In this case, the upper tier that is available in the pool is SSD. The following screen captures show details of performance improvement due to extent migration by Easy Tier.

17 Figure 12: Improvement in write I/O by Easy Tier extent migration Summary This white paper provides a brief introduction to the IBM System Storage SVC cluster with the IBM Easy Tier feature in the release along with upgrade considerations. In the version, three-tier support is introduced along with the balancing function. The limiting function handles performance monitoring and denies extent to migrate if the destination disk is already overloaded or gets overloaded after extent migration. The balancing function deals with extent migration within the same storage tier. Due to the balancing function, the balancing script is not required from the release. Significant changes have happened in Easy Tier licensing in the release which is also covered in detail. The IBM Easy Tier feature improves performance by moving hotter extents to upper high-speed tier and cold extents to the lower tier disk. Moving of inactive data automatically on cheaper storage instead of high-cost SSDs can save data retrieval time. This also saves the costumer s money to buy additional SSDs. 15
