Note to Presenter: Present to customers and prospects to provide them with a high-level overview of the EMC VNX family—the VNX series and the VNXe series. For additional technical content, see “Customer Technical Presentation: EMC VNX Series Technical Review” and “Customer Technical Presentation: EMC VNXe Series” on Powerlink.
These EMC 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 EMC VNX family delivers the world’s simplest array to manage and the world's highest midtier performance.The VNX family is designed from the ground up for virtual application environments—from simple, money-saving server and storage consolidation for small business, to the next-generation virtual data center applications.The VNX family is comprised of two series: VNXe series and VNX series. The VNXe series represents the entry point of the VNX family, and is designed specifically for small-to-medium businesses (SMB), remote offices or branch offices (ROBO), or departmental applications where traditional storage administration skills may not be available.The VNX series is the next-generation midrange platform. For those of you familiar with EMC’s legacyCLARiiON and Celerra platforms,the VNX series combines the capabilities of these systems into a single modular unified storage offering.The entire VNX family shares the tradition and builds on years of know-how of the world’s most popular SAN and NAS platforms—CLARiiON and Celerra. Everything EMC has learned about high performance and high reliability culminates with the VNX family.EMC Unisphere provides a common unified management capability for EMC’s VNX family and CLARiiON and Celerra products. And as you will see, Unisphere also provides a way to simplify and automate other common storage management tasks, such as replication and backup reporting.
Note to Presenter: View in Slide Show mode for animation. One of the biggest shifts in IT is, of course, the move to server virtualization. It continues to have a profound impact on how we look at storage provisioning today.In the “good old days,” we typically had a single application running on a server. To meet performance objectives, we would create a RAID group and then carve out LUNs statically. With virtualization, that has all changed.Note to Presenter: Click now in Slide Show mode for animation. Virtualization enables you to save on infrastructure and run more applications on fewer physical servers. To meet the growing and dynamic needs of the business, server virtualization pools server resources and enables dynamic provisioning and optimization of compute power and applications according to shifting business needs. To stay relevant, storage had to embrace this same pooling paradigm. Just like VMware vMotion allows you to move things around on the server side, EMC saw the need to allow data to move dynamically across different tiers of drives (from high performance to lower cost/high capacity) according to its business activity. Not only did such data movement make sense, it also had to be fully automated and self-managing.As the storage system takes on more and more automation and ongoing optimization, it needs more processing power. EMC knew this to be a central requirement for its next-generation midtier storage systems.
Note to Presenter: View in Slide Show mode for animation. The data center can be viewed as an “information factory” where data is received, processed, refined, and then stored for future use.When business needs call upon that data to facilitate transactions and decision making, the data must be made available in a timely fashion.The core components of the data center are, of course, processors, storage, and data. So when we plan an IT strategy, it is very important that we look at long-term trends.Thanks to Moore’s Law, CPU processing capabilities have been good to us. Doubling every 18 months or so, an average processor is today 103 times more powerful than it was at the turn of the decade. That is good, since the amount of data we have accumulated has grown 124 times in the same period. Both growth rates show no sign of stopping and can be expected to continue to grow in the next decade.But what about storage? Can we keep up? This is, of course, a challenge. When we look at drive density, the answer is, “almost, but not quite.” We find that disk drive density has grown steadily at 43 percent year-over-year. So data and CPU is growing faster than the disk drives’ ability to store the processed data.Note to Presenter: Click now in Slide Show mode for animation. And that is not particularly good news when budgets are growing less than that. This means IT is under constant pressure to find more efficient storage strategies and at the same time increase the amount of data each employee manages.In addition, hard disk drive performance remains unchanged—15K rpm drives are still the fastest.Data center challenges can be summarized as flat budgets, escalating complexity, relentless data growth, and increased business demands; to address these we need storage systems that are affordable, simple, efficient, and powerful.
Note to Presenter: View in Slide Show mode for animation. When you take into account Moore’s law and multi-core CPUs (compute density), you can foresee 100X improvement in CPU performance in the next decade…HDD performance has not and cannot keep pace. Spinning disk drives—15K rpm drives—came out 10 years ago and cannot go faster due to the physics of spinning media.This creates a I/O bottleneck. Customers have dealt with this by striping/short-stroking hundreds to thousands of drives with a small amount of data, yielding incredibly poor utilization. A better answer is Flash with high performance AND high utilization.
Note to Presenter: View in Slide Show mode for animation. 15K drives cannot handle the highest-performance data, and are not cost-effective for low activity or “cold” data.For the highest-performance data, Flash hast the lowest cost per transaction ($/IOPS)—about 75 percent lower than 15K drives. And by the way Flash is 95 percent cheaper than 15K on mWatt/IOPS.For cold data, high capacity near-line hard disks have 75 percent lower cost per gigabyte versus 15K drives. So, how can you optimize both cost and performance without the overhead of manual tiering?
Note to Presenter: View in Slide Show mode for animation. Many customers’ first reaction is that they can’t afford Flash drives or that Flash is too expensive. Let’s take a look at the economics of different drive types.Not surprisingly, when looking at $/GB or mWatt/GB, (i.e., the Capacity Acquisition Cost and Capacity Power Cost in the top row), 7200 NL-SAS drives are the most cost-effective drives. However, on a $/IOPS and mWatt/IOPS basis (the bottom row), Flash drives are almost 3x and 47x more efficient, respectively, than the next most efficient drive type. This means that Flash drives make more efficient use, on a per transaction basis, of a customer’s investment. With the EMC FAST Suite, including FAST Cache and FAST VP, customers need only purchase a small number of Flash drives to handle the “hot” workloads, since data is automatically moved to cost-effective HDD as it cools down. And a little Flash goes a long way!EMC calls this its FLASH 1st data strategy, ensuring that hot data is stored on Flash drives for maximum performance at the optimal $/IOPS, then tiering and storing the data as it cools on to HDD for the lowest $/GB. As a result, customers can take advantage of the transactional benefits of Flash, while still storing the majority of their data on cheap 7200 NL-SAS drives for the lowest TCO. Customers implementing a FLASH 1st data strategy may install a mix of drive types to reap the advantages of each. Example: 5 percent Flash, 20 percent SAS, 75 percent NL-SAS. Note to Presenter: Each customer’s environment and data skew is different and the drive mix is tailored to that.Lastly, what is particularly interesting on the slide is that 15k SAS, the mainstay of storage drives, is NEVER the most efficient drive type. It is neither the most cost-effective on a per-transaction basis nor on a per-capacity basis.
Note to Presenter: View in Slide Show mode for animation. There’s something called the 90/90 rule:Ninety percent of data’s activity occurs in first 90 days of its life. Once data is 90 days old, there’s only a 10 percent chance anybody will ever look at it…and after another quarter—10 percent of that. By the end of the year, that’s a 0.1 percent chance that the data will be touched! It’s mostly stone cold. When young and hot, where should we put it?When the data is highly active we place it on flash drives, when it becomes cold, we move it to high capacity near-line drives. The 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 that customers never have to make concessions for cost or performance.Note to Presenter: Click now in Slide Show mode for animation. Highly active data is served from up to 2 TB of Flash drives with FAST Cache, which dynamically absorbs unpredicted spikes in system workloads. Note to Presenter: Click now in Slide Show mode for animation. As that data ages and becomes less active over time, FAST VP 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, which saves application and storage administrators time and money by intelligently doing the work associated with pre- and post-provisioning tasks.
The FAST Suite improves performance and maximizes storage efficiency by enabling this FLASH 1st strategy. FAST Cache, an extendable cache of up to 2.1 TB, gives a real-time performance boost by ensuring the hottest data is served from the highest-performing Flash drives for as long as needed. FAST VP then complements FAST Cache by optimizing storage pools on a regular, scheduled basis. 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 1 GB 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 and Unisphere Analyzer. Unisphere Quality of Service Manager 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 that allows detailed statistics to be gathered for the VNX system to enable troubleshooting.
Note to Presenter: View in Slide Show mode for animation. So, how much Flash is needed?For a quick calculation, we can ask three simple questions. Based on the answers, we can show how determine Flash is needed.How much data is under management today?How much is your data growing each year?How long does your data stay hot?Remember that you only need enough Flash to keep your active data on.Let’s look at an example: (Note to Presenter: Click now in Slide Show mode for animation.)30 TB of data is under management50 percent growth year-over-yearData stays active for about 60 daysWith this data we can calculate how much Flash is needed.
Note to Presenter: View in Slide Show mode for animation. Here are the calculations.First, look at the growth rate as a percentage (i.e., 10%, 20% 30%, etc.).Further down, look at the point where that growth rate intersects with the average number of days the data stays hot (or active) (i.e., 30 days, 60 days, etc.).The intersection point is the guideline of how much Flash is needed in your environment. In the previous example, with 50 percent growth year-over-year, with data staying active for 60 days, you would need 5 percent Flash. Generally speaking, EMC is seeing customers going out with between 4 percent and 6 percent of Flash.Remember that the cost of a small amount of Flash is offset by allowing you to utilize a large amount of inexpensive, high-capacity drives and let the FAST automatically tier the data.
So let’s look at configurations for the example.To hit the performance needed with a monolithic configuration, you would need a VNX5500 with 200 short-stroked 15K drives.With FLASH 1st (assume first 20 percent in FAST Cache), you could use a VNX5300 (RAID 5 for Flash and SAS in pool, RAID 6 for NL-SAS in pool) and the FAST Suite software.Using the model for 30 TB, 50 percent growth, and 60 days hot, with the FLASH 1st strategy you are now able to reduce the footprint by 65 percent, reduce the power by 75 percent, AND increase the performance by 2x…and the cost comes down.That’s the power of FLASH 1st.
EMC and VNX is the best storage for virtual environments.According to a Wikibon survey conducted in April 2011, EMC with VNX was voted best product for VMware integration, based on two factors—the importance of the integration from a customer’s perspective, and the quality of the integration.According to the September 2011 “Goldman Sachs IT Spending Survey,” EMC is the storage vendor of choice in virtualized server environments.And in 2012, VNX and VNXe were voted the 2012 winners in the Storage Virtualization categoryby the Virtualization Review Reader’s Choice Award and Buyers Guide.
The VNX series platform is optimized for virtualization with over 75 points of tight integration.Until today, one of the major challenges facing users in virtual environments was a management complexity gap. Storage administrators have access to detailed information on the array, but lack visibility into how the virtual server is configured and which virtual machines are consuming what for storage resources. VMware administrators, on the other hand, can see the details of the virtual server environment and virtual machines, but lack visibility into the storage system. On the VNX series, Unisphere, together with vCenter Server and VASA (VMware vStorage APIs for Storage Awareness) integration, makes storage management in a virtualized environment a seamless experience. Each administrator can use their familiar interface to gain full visibility into virtual and physical resources, transparently provision storage, integrate replication, and access and offload all storage functions to the storage system. To further drive efficiency in the VMware space, EMC has delivered on the VMware vStorage APIs for Array Integration (VAAI) for both SAN and NAS connections, allowing the VNX series to be fully optimized for virtualized environments. This technology offloads VMware storage-related functions from the server to the storage system, enabling more efficient use of server and network resources for increased performance and consolidation.Letting the VNX series perform common data management tasks, like vMotion, results in more network I/O, more virtual machines, and faster response time.The VNX series delivers unmatched VMware management integration and optimization and is ideal if you are running VMware.
The resulting solution is the EMC VNX Storage Analytics Suite, which includes two components, the first of which is a light version of VMware’s vCenter Operations Manager (vC Ops) Enterprise tool, which is specifically built to provide storage-related analytics. You can still map your VM infrastructure (like Unisphere) however the most significant portion of the tool is the storage-related metrics and analytics. The second component is the EMC VNX Connector which includes the adapter that feeds the necessary VNX storage metrics into vC Ops and the integrated customized dashboards that provide performance and capacity metrics, proactive information to help administrators make informed decisions, heat maps etc.A single tool that helps admins to pinpoint the problem, diagnose it and take action to fix the problem.
You can view storage systems, and within those systems you can also see the subcomponents in a hierarchal format.These relationships enable the administrator to quickly view the most relevant anomalies and resolve issues quickly.
All block performance statistics are available – including FAST Cache statistics.
In summary, the VNXe series systems are simple, efficient, and affordable unified storage designed for the IT generalist who needs to be up and running quickly. It’s easier than ever.And the VNX series of systems offer the most scalability and flexibility, and is the most powerful midtier unified storage solution. It’s reliable, as always.
The software packs bundle EMC’s advanced data management suites:FAST Suite automatically maximizes capacity and performance efficiency. FAST enables a dynamic FLASH 1st data management strategy where just a small number of Flash drives are used to deliver the highest performance for high activity data, and low activity data is constantly moved to the most cost-effective drive type. This suite, only available for the VNX series, includes Fully Automated Storage Tiering for Virtual Pools (FAST VP), FAST Cache, Unisphere Analyzer, and Unisphere Quality of Service Manager.Security and Compliance Suite helps ensure that data is protected from unwanted changes, deletions, and malicious activity. Data is encrypted where it is created for protection anywhere outside the server. File-Level Retention is used to meet compliance requirements. Integration with third-party anti-virus checking, quota management, and auditing applications provides added data protection, security, and peace of mind. This suite for VNX series includes Event Enabler (anti-virus, quota management, auditing), File-Level Retention, and Host Encryption.This suite for VNXe series includes Event Enabler (anti-virus) and File-Level Retention.Local Protection Suite combines snapshots and clones with point-in-time recovery with DVR-like rollback capabilities for business continuity on block-based storage, allowing recovery of production applications with minimal data exposure. Application owners can tune recovery point objectives based on criticality of data and perform faster recovery through self-service capabilities. Copies of production data can be used for development, testing, decision support tools, reporting, and backup acceleration. This suite for VNX series includes VNX Snapshots, SnapView, SnapSure, and RecoverPoint/SE CDP (continuous data protection).This suite for VNXe series includes SnapSure.Remote Protection Suite delivers unified block and file replication, providing disaster recovery for both NAS and SAN environments. It delivers disaster recovery protection for any host and application without compromise—with immediate DVR-like rollback to a point in time. Capabilities include compression and deduplication for WAN bandwidth reduction, application-specific recovery point objectives, and replication options for one-to-many configurations. This suite for VNX series includes Replicator, MirrorView/A, MirrorView/S, and RecoverPoint/SE CRR (continuous remote replication).This suite for VNXe series includes Replicator (iSCSI and NAS).Application Protection Suite automates application-consistent copies and enables you to recover to defined service levels. User roles enable self-service copy management, while improving visibility for all application recovery points. Alerts are generated automatically, providing fast resolution to recovery gaps. Integrated reporting can prove compliance with protection policies. Applications supported include Oracle; Microsoft Exchange, SQL Server, and SharePoint; VMware; and Hyper-V.This suite for VNX series includes Replication Manager and Data Protection Advisor for Replication Analysis. This suite for VNXe series includes Replication Manager.
VNX Snapshots is the new point-in-time copy for block data. Because it supports 256 writable snaps per LUN and snaps of snaps, it is ideal for test/dev and logical point-in-time disk backups.In this example, we see a LUN that has a daily snap for point-in time backup. The Tuesday snap was further snapped at 8 AM for recovery and at 10 AM for multiple purposes—backup, analysis, and test/dev. These snaps are writable logical copies and more efficient than full physical copies.Note to Presenter: VNX Snapshots are targeted for shipment in Q3 2012.

The VNXe series provides a choice of hardware platforms and capabilities to meet you specific needs.Common capabilities include:6 Gb/s SAS disk interface delivers the highest bandwidth for high performance and full redundancy for high availabilitySupport for enterprise Flash, 15k rpm high-performance and high-capacity 7,200 rpm near-line disks.Standard 1 Gigabit Ethernet ports for shared iSCSI and NAS connectivityOptional 10 GB Base-T Ethernet ports for shared iSCSI and NAS connectivityI/O expansion slotsManagement and protocols: Unisphere, CIFS, NFS, iSCSIAdvanced functionality: Thin provisioning, and File Deduplication with CompressionModels available supporting Self Encrypting Drives for Data at Rest Encryption requirementsChoose:VNXe3150 for compact, highly integrated solutions with class-leading features and the option of single or dual controllers to achieve the right combination of price, performance, and availability.VNXe3300 for greater storage scalability and performance, and two I/O slots per controller for added expandability.
FAST Cache is part of the FAST Suite for VNX arrays, which also includes Fully Automated Storage Tiering for Virtual Pools (FAST VP). FAST VP automatically moves data to the most appropriate storage tier based on sustained data access and demands over time. FAST Cache automatically absorbs unexpected spikes in application workloads, providing immediate performance benefits for burst-prone data. FAST Cache and FAST VP can be used alone or together.This solution demonstrates the benefits of FAST Cache only. FAST CacheFAST Cache uses Flash drives to add an extra layer of cache between DRAM cache and rotating disk drives, thereby creating a faster medium for storing frequently accessed data. FAST Cache is an extendable, read/write cache. It boosts application performance by ensuring that the most active data is served from high-performing Flash drives and can reside on this faster medium for as long as is needed. FAST Cache is most effective when application workloads exhibit high data activity skew. This is where a small subset of data is responsible for most of the data set's activity. Fast Cache is more effective when the primarily block reads and writes are small, fits within the 64K FAST Cache track. The storage system is able to take advantage of such data skew by dynamically placing data according to its activity. For those applications whose data sets exhibit a high degree of skewing FAST Cache can be assigned to concentrate a high percentage of application IOPs on Flash capacity.FAST Cache tracks data activity at a granularity of 64 KB and promotes hot data into FAST Cache by copying it from the HDDs to the Flash drives assigned to FAST Cache. Subsequent I/O access to that data is handled by the Flash drives and is serviced at Flash drive response times—this ensures very low latency for the data. As data ages and becomes less active, it is flushed from FAST Cache to be replaced by more active data.A small number of Flash drives implemented as FAST Cache provides a greater performance increase than a large number of short-stroked HDDs.FAST Cache is particularly suited to applications that randomly access storage with high frequency, such as Oracle OLTP databases. In addition, OLTP databases have inherent locality of reference with varied I/O patterns. Applications with these characteristics benefit most from deploying FAST Cache.
High locality of data is important to realize the benefits of FAST VP. When FAST VP relocates data, it moves the entire slice to the new storage tier. To successfully identify and move the correct slices, FAST VP automatically collects and analyzes statistics before relocating data. Customers can initiate the relocation of slices manually or automatically by using a configurable, automated scheduler that can be accessed from the Unisphere management tool. The multi-tiered storage pool allows FAST VP to fully use all three storage tiers: Flash, SAS, and NL-SAS. Like FAST Cache, FAST VP works best on data sets that exhibit a high degree of skew. FAST VP is very flexible and supports several tiered configurations, such as single tiered, multi-tiered, with or without a Flash tier, and FAST Cache support. Adding a Flash tier can locate “hot data” on Flash storage in 1 GB slices.
