戴尔公司和NetApp公司存储对比

Competitive AnalysisOverview∙Compellent was purchased by Dell in Feb. 2011. Prior to the purchase,Compellent generally realized impressive growth off of a small revenue baseover the past couple of years. Compellent reported $110M for the first ninemonths of 2010. In Q3 (Sept. 2010), Compellent reported $42M.∙Prior to the Dell purchase, Compellent‘s sales model was channel-only andconcentrated mostly in the U.S., although it had begun international expansion.Dell is attempting to retain Compellent‘s partner ne twork, but is looking tobroaden sales through its existing channel and direct sales organization.∙Compellent has been facing severe margin pressure, especially since its maindifferentiation, related to automated tiering, has recently been neutralized. Thecompany‘s pricing strategy has traditionally been based on aggressively pricedfirst-time installs, with more margin-rich follow-on sales. Compellent bases itssoftware licensing on capacity tiers.∙Compellent claims about 2,300 customers today. Most of its customers are inthe MSE tier. The sweet spot for Compellent is in the 200TB range. Theaverage sale is around $90K U.S.∙Compellent has won numerous accolades from media sources, including ―topmid-range array‖ by Storage Magazine.Positioning∙Compel lent‘s main differentiation is automated tiering. It uses the term ―fluiddata architecture‖ to describe its automated tiering capability. Compellent‘stiering capability includes not just disk types, but also radial placement on disks.This underpins Comp ellent‘s claims to support ‗nine tiers‖ of storage, based onSSD, FC, and SATA disks, plus three levels of radial placement on FC andSATA disks.∙Compellent also touts ease of use. Its management GUI is Java-based andruns on a discrete node in the SAN. It is remotely accessible from any nodewith Web access.∙Compellent supports many of the advanced features touted with enterprisedisk arrays: thin provisioning, disaster recovery, application-consistent dataprotection, VMware integration, and advanced virtualization. Compellent‘ssnapshots and clones are both pointer-based, comparable to NetApp‘sapproach. Compellent supports consistency groups for both snaps and mirrors.∙Compellent‘s value proposition hinges on its ability to quote mostly SATA disksfor traditional workloads and ongoing capacity expansion.Strengths∙Well positioned in automated storage trend; considered top innovator in this area∙Compelling value proposition related to usable capacity, TCO, value; fairly complete set ofadvanced features∙Simple, elegant usability∙Snaps, clones compare favorably to NetApp‘s technology; capable replication; applicationintegration∙Expansive network of U.S. partners; simple value proposition Compellent Storage Center Competitive One-PagerWeaknesses∙Inefficient, inflexible architecture: limited efficiency technologies, silo-plus-gateway approach to unified storage; optimized mainly for FC—not best-in-class for otherprotocols∙Limited product breadth: over-priced for ROBO/departments; under-designed for data center∙Uncompetitive pricing model: capacity tiers for software offsets value of automated tiering; overly expensive services packages∙Virtualization caveats: 32-bit core; large chunk size, heavy metadata model, and finite ceiling on number of storage objects/addressable memory; inhibits scalability(60-300 spindles max); scaling challenges, as follows: 512KB page/60TB activedata; 2MB page/150TB of active data; 4MB page/300TB of active data∙Management challenges: management environment is designed around individual tasks—not across workflows—and so is onerous for large environments; requiresseparate management node, which is non-HA (and so a point of failure)Why NetApp?∙Best-in-class technology partner: NetApp is a storage leader, highly profitable, and recognized for leading the market in innovation. In addition, we haveestablished strategic partnerships with key infrastructure providers to deliverproven end-to-end solutions.∙ A better architecture for today and tomorrow: NetApp has a highly differentiated unified architecture that brings significant value to customers at all levels of business, across all types of applications, and for all types of network implementations.∙Better and more complete product set: NetApp can address a much broader scope of storage requirements and business objectives with best-in-classsolutions.∙Greater efficiency and cost containment: NetApp is a leader in storage efficiency, combining the industry‘s most expansive lineup of native datareduction technologies with intelligent caching to bring savings both by reducing data footprint and optimizing the use of low-cost/high-capacity disk media.∙More effective management and higher uptime: NetApp has proven greater-than-five-nines uptime delivered through the most comprehensivemonitoring/reporting/diagnostics functionality of any modular array platform. With ironclad uptime, we also have the most effective management environment of any storage contender, accomplished with the most expansive integration and automation, as well as the most complete and effective software functionality. Questions To Ask the Customer∙Efficiency: What kind of data growth are you seeing? Which applications are seeing the highest growth? What ideas or objectives do you have on handling growth and containing capacity costs in your environment? What do you know about NetApp‘s efficiency capabilities? What do you know about our latest SPC-1 and SpecSFS 2008 results? Have you seen our Efficiency Calculator?∙Consolidation: What type of existing storage do you have? What is your strategy for evolving your storage infrastructure going forward? How much doyou know about NetApp‘s unified architecture?∙Virtualization: Where do you stand on virtualizing your server and desktop infrastructures? What do you see as your biggest storage challenges as you ∙move forward with your virtualization plans? What do you know about NetApp‘s SnapManager for Virtual Infrastructure and value-add capabilities for keyvirtualization environments?∙Cost containment and value: What aspects of storage are taking most of your budget today? What are your storage investment objectives for your next budget cycle? Where do you want to cut back? Where would you like to invest more?How much do you know about NetApp‘s 50% capacity reduction guarantee? Are you familiar with NetApp‘s‘ software stack? What do you know about NetApp‘s OnCommand management software?Things To Remember∙NetApp‘s efficiency story is much more comprehensive than Compellent‘s.We are considered the leader in storage efficiency.∙We have the industry‘s premier unified architecture. It provides scale-up and –out growth paths, integrates flash technology for dynamic tiering, anddelivers the most capable management functionality of any disk arrayplatform.∙We enable Virtual Storage Tiering with our Flash Cache technology. It is a much more effective use of flash technology than Compellent‘s ―Fluid Data.‖100% snapreserves, greatlylowering usablecapacity.Administrators can set reservations as high or as low as theywish. Because NetApp and Compellent use a similar model forsnapshots, capacity utilization is about the same. But NetApphas a couple of important differentiators with respect tocapacity utilization: native block-level dedupe on everythingstored and high-performance RAID-DP (obviates the need forRAID mirroring).U-Turn: Have you seen our Efficiency Calculator?Our systems aresimpler to usethan NetApp‘s.Facts: NetApp continues to evolve our managementinterfaces to greater simplicity and to streamline deployment.When it comes to managing a dynamic, growing storageenvironment, NetApp delivers unprecedented efficiency withour management suites.U-Turn: Have you seen any of NetApp‘s management suites?These are truly unique in the industry.NetApp is behindthe curve onsupporting SSD.Facts: We are taking a broader, more progressive approachto flash technology than many of our competitors.U-Turn: Are you familiar with NetApp‘s dynamic tieringapproach with our Flash Cache technology?强制性存储中心竞争一个寻呼机概述∙∙Compellent 是由戴尔在 2011 年 2 月购买的。
