10 VNX Series Storage Arrays - Unified Storage Platforms Announcing the record breaking new VNX Family of Unified Storage Platforms. These hardware and software solutions are simple to provision, efficient with lower capacity requirements, affordable for any budget, and powerful enough to handle the demands of virtual applications.In fact, the VNX family delivers the world’s simplest array to manage and the world's best mid-tier performance.

They can start with file or block and be upgraded to support both.Please take a moment to review this slide.FileBlock11

For different connectivity options like: SAN (i.e. block connectivity with iSCSI, Fibre Channel or Fibre Channel over Ethernet), NAS (i.e. CIFS, NFS with pNFS or Multi-Path File System) or Cloud ( i.e. with Atmos for REST or SOAP), the VNX platform addresses each with its purposed built modular architecture, simultaneously. The benefits of the modular unified architecture include:Offering a modular design with optimized controllers for the protocols and workload to be served on. You can add and scale out the X-Blades independently and without impacting the overall systemBoth controllers benefit from a central storage pool for LUN provisioning ensuring no stranded unused resources. Frequently accessed data is automatically moved to high-performance Flash drives and infrequently accessed data is moved to high-capacity/low-cost disk drives.Another advantage of the modular architecture is that EMC has packaged the X-Blades into a NAS gateway model. This gateway supports FC SAN connect to EMC Block storage (Symmetrix, VNX and CLARiiON) and scales with support for up to four storage arrays. So, if you are looking for more storage scale, adding memory, adding drives over and above what is typically supported, add a gateway in front of four VNX7500’s and you can scale up to 8 X-Blades, up to 8 storage processors and up to 4,000 drives.All the power you need from the VNX series modular architecture.Note to Presenter: The graphic depicting eight storage processors is based on a configuration that includes a VNX gateway front-ending four VNX Series storage arrays.Note to Presenter: Click to show the red box, indicating that the following slides (9-40) cover hardware and base software for File and Block components of the VNX solutionHDDSelf-optimizing storage poolsActive Data is automatically moved to FLASH for fastest performanceInactive Data is automatically moved out of FLASH to large disks for lowest capacity costFully Automated.

13 New FLASH 1st Data Strategy for Symmetrix V-Max and VNX Series Hot data on fast Flash SSDs—cold data on dense disks“Hot” high activityHighly active data is stored on Flash SSDs for fastest response timeAs data ages, activity falls, triggering automatic movement to high capacity disk drives for lowest costFLASH SSDHigh Cap. HDDData ActivityThe VNX series has been expressly designed to take advantage of the latest innovation in Flash drive technology, maximizing the storage system’s performance and efficiency while minimizing cost per GB. When even a few Flash drives are combined with the EMC FAST Suite, an unrivaled set of software that tiers data across heterogeneous drives and boosts the most active data to cache, customers receive the optimal benefits of a FLASH 1st strategy. FLASH 1st, available only through EMC, ensures customers never have to make concessions for cost or performance. Highly active data is served from up to 2TB of Flash drives with FAST Cache, which dynamically absorbs unpredicted spikes in system workloads. As that data ages and becomes less active over time, FAST VP (Fully Automated Storage Tiering for Virtual Pools) tiers the data from high performance to high capacity drives in 1 GB increments, resulting in overall lower costs –regardless of application type or data age.Best of all, this all happens automatically based on customer-defined policies, saving application and storage administrators time and money by intelligently doing the work associated with pre- and post-provisioning tasks.Movement Trigger“Cold”low activityData Age

Customers define how and when data is tiered using policies that dynamically move most active data to high-performance drives (e.g. Flash), and less active data to high-capacity drives, all in one-gigabyte increments for both block and file data.Together, they automatically optimize for the highest system performance and the lowest storage cost simultaneously.In addition, the FAST Suite includes Unisphere Quality of Service Manager (UQM) and Unisphere Analyzer. UQM provides even greater flexibility to tune the system by allowing specific controller resource adjustments to be dynamically applied to specific workloads (LUNs) as those workloads change throughout the day. Unisphere Analyzer is a powerful tool integrated to Unisphere which allows detailed statistics to be gathered for the VNX system to enable troubleshooting.* Not available for VNX5100.

FAST Cache is supported for Block and File LUNs. FAST Cache combines hardware and software elements:Note to Presenter: The numbers in the picture roughly represent the relative costs of DRAM versus Flash Drives Versus conventional performance disk drives (e.g. 15K SAS) where the conventional drives are normalized to a price of $1.Hardware—Enterprise Flash drives with FAST Cache drive SKUs for new purchases. Customers can also use existing Flash drives that meet the appropriate configuration.Software—FAST Cache Software. Platform based (VNX5100, VNX5300, VNX5500 etc.), one FAST Cache license per system. The license enables FAST Cache usage for all allowed configurations. It is available as an individual product or as part of the FAST Suite and total efficiency pack (described above). It is chargeable in all cases.FAST cache provides improved performance for most workload types, especially those that experience frequent and unpredictable large increases in IO activity (such as VMware View boot storms) and is a cost effective solution compared to the cost of DRAM, while also, potentially, allowing more extensive usage of high capacity NL-SAS drives. Adding Flash drives as FAST Cache will improve cache hit rates from the traditional 20-30% up to 60-70%.Using FAST Cache with FAST VP (see later in this presentation) together, allows unprecedented Flash scaling while also addressing short and longer term data access trends cost effectively for the most optimal efficiency solution.As most workloads have a mixture of reads and writes, FAST Cache supports Read/Write mode so the benefits extend to all IO activity on the system, not just reads (and this requires RAID 1 mirrored pairs).If data is already on Flash drives (for instance it is in a LUN on a Flash RAID Group), it will be excluded from Fast Cache processing.DRAMPerformanceFAST Cache8CapacityDisk Drives1FAST SUITE

The combination of FAST Cache and FAST VP addresses the perennial storage management problem: the cost of optimizing the storage system. In many cases prior to FAST and FAST Cache, it was simply too resource intensive to perform manual optimization and many customers simply overprovisioned storage to ensure the performance requirements of a data set were met. With the arrival of Flash drives and the FAST Suite, we have a better way to achieve this fine cost/performance balance:The classic approach to storage provisioning can be repetitive and time-consuming and often produces uncertain results. It is not always obvious how to match capacity to the performance requirements of a workload’s data. Even when a match is achieved, requirements change, and a storage system’s provisioning may require constant adjustment. Storage tiering is one solution. Storage tiering puts several different types of storage devices into an automatically managed storage pool. LUNs use the storage capacity they need from the pool, on the devices with the performance they need. Fully Automated Storage Tiering for Virtual Pools (FAST VP) is the EMC® VNX® feature that allows a single LUN to leverage the advantages of Flash, SAS, and Near-line SAS drives through the use of pools. FAST solves theses issues by providing automated sub-LUN-level tiering. FAST collects I/O activity statistics at the 1 GB granularity level (known as a slice). The relative activity level of each slice is used to determine which slices should be promoted to higher tiers of storage. Relocation is initiated at the user’s discretion through either manual initiation or an automated scheduler. Through the frequent relocation of 1 GB slices, FAST continuously adjusts to the dynamic nature of modern storage environments. This removes the need for manual, resource-intensive LUN Migrations while still providing the performance levels required by the most active dataset, thereby optimizing for cost and performance simultaneously.Tier 2Most activityNeutral activityLeast activityFAST SUITE

The VTEC includes the virtual tape engines (VTEs), which perform all the tape emulation activities when reading tape information from disk, or writing tape volume to disk.Each of the VTEs provided with Disk Library for mainframe can emulate up to 256 tape drives per VTE, and with six VTEs the DLm960 provides 1,536 tape drives.The VTEs support FICON connectivity to the mainframe host, and each VTE provides a maximum throughput of 200 MB/s with FICON. The DLm960 can accommodate up to six VTEs, providing throughput of 1.2 GB/s.Upon request VTE’s can be configured to support the older ESCON/SBCON interface while clients migrate to FICON.The VTE is transparent to the mainframe host; the host sees it as another tape device just like a physical tape library.The VTE writes each VOLSER (volume serial number) as a file on the back-end storage.Each tape cartridge can be up to 16 TB in size; however, the disk space that is consumed is based only on the physical data that is written to disk and not based on the cartridge size.The VTE supports hardware compression, which typically is 2.4:1 to 2.7:1; however, since compression depends on data, higher compression rates are possible.The second component is the back-end storage.The back-end storage uses the 1 TB SATA II drives with RAID 6 protection. Each disk tray also includes one hot spare drive for additional protection.The tape volumes are kept as files on the back-end storage and can be shared among all the VTEs for higher availability.VTECBack-end storageEMC Disk Library for mainframe

As mentioned earlier, each VTE can emulate up to 256 tape drives.The Tape Administrator will map the specific range of tape drives to go to a specific VTE. In this example, tape drives 0000 to 00FF will be directed to the first VTE in the Disk Library for mainframe, and tape drives 0100 to 01FF to the next VTE and so on.Each of the VTEs can access part or all the tape volumes on the back end. This is important for high availability, which we’ll discuss later.The tape volumes (VOLSER) are written to disk as files. The file name is identical to the tape VOLSER and will occupy just the amount of space it requires, as there is no pre-allocation of files on the disk.When a tape is being scratched, the file name changes and a tilde (“~”) sign is added to the beginning of the file name. When scratching a tape, you have the option of not deleting the information in case you would like to recover the tape at a later date.The Disk Library for mainframe is self-maintained and when space utilization is below a specific threshold, Disk Library for mainframe will automatically delete the earliest scratch files to free up space.
