V7000产品高级特性介绍.ppt

* 旧平台存储挂载，内部数据拷贝，拷贝过程中不影响应用对数据的持续访问 算法把经常访问到的数据块迁移到SSD盘中，提高对数据访问的响应性能 * andreas_baer@ * Striping – extent size * andreas_baer@ * For internal storage, the tier is selected automatically. But Storwize V7000/SVC cannot recognize the drive type. * andreas_baer@ * Easy Tier is active because we have MDisks with two different tiers. The internal SSD array is recognized automatically, the tiers for the external MDisks must be defined manually. Note: If you make a wrong definition for the external MDisks, then Easy Tier optimizes into the wrong direction!See in the screenshot the tier of mdisk1! * andreas_baer@ * 同一卷可以达到最多256个快照卷，不影响数据访问性能，结合flashcopy manager软件，可以有效的与应用配合，达到基于应用的数据保护等特性 内部volume的镜像，只要V7000管理的的空间，均可以使用此功能，不影响数据的访问 软空间，例如：可以创建3个100G的Volume在1个100G的磁盘空间中，提高存储空间的使用率 可以挂载业界主流的光纤存储阵列，V7000中的所有功能均可应用于所接入并管理起来的存储中 这是其他厂家传统存储所不具备的功能 基于容灾的应用方式，可以使用TPS-R进行管理使用，自动化程度非常高 {DESCRIPTION} This slide contains the topics that are covered by the narration written in the transcription of this slide. {TRANSCRIPT} We’ve described at a high level the benefits, the many benefits that IBM RtC can provide to your customers in their NAS environments, maximum data compression, transparency and high performance. One of the first questions your customers may ask you as you begin your dialogue is how can this possibly be true it seems too good to be true, how could I possibly not negatively impact my storage performance? And the answer is because we’re going to physically move cache and store less data. As mentioned depending on the application you’ll be able to compress the data between 40-80%; this means we’ll physically store 40-80% less data on the physical backend. The slowest piece of a customers storage array will be the disk drives and as the actuators work and manage the data off of those disk arrays. By storing less data there will be much less workload, much less I/O required by the physical disk backend. Secondarily because we’re now compressing and storing less data i
