EMC Competitive Analysis

Overview

·         Recognized brand, large installed base

·         >50% of sales are through channel and OEMs

·         50% revenue increase YoY

·         Strong Customer Base

Strengths

·         N+1 clustering for high availability

·         Integrates into existing EMC storage installations

·          “All-in-one” NAS, iSCSI, and Fibre Channel connectivity – Separate OS*

·         File-level deduplication – Gen 1 Released in 09

·         File-level retention, similar to SnapLock Compliance

·         Thin Provisioning with Automated Volume Manager

·         Async replication process for iSCSI and NAS with non-transparent failover

Weaknesses

·         At least two operating systems to manage

  • DART on Celerra
  • FLARE on CLARiiON
  • RedHat Linux on Celerra Control Station

·         Multiple management software products

  • Celerra Manager for NAS/iSCSI
  • Navisphere Manager on CLARiiON

·         No true Unified Storage

·         Deduplication not supported on iSCSI and with VMware

·         CLARiiON virtually provisioned LUNs are not supported and cannot be provisioned to Celerra

·         Celerra Raid andDrive configurations are based on templates and are limited


 

Netapp Competitive Analysis

Overview

·         Up and coming

·         YOY market share increasing

·         Strong customer base

Strengths

·         Easy Implementation and Management

·         N+1 clustering for high availability

·         True “All-in-one” NAS, iSCSI, and Fibre Channel connectivity – Single OS*

·         Block-level deduplication

·         File-level retention

·         True Thin Provisioning – Virtual Provisioning for dynamic increase and decrease of Volume sizes

·         True NAS File Management

Weaknesses

·         Storage Utilization  based in Raid DP

·         Time based Snaps do work with VMware Managed Storage

  • Need RDM to do Snaps
  • LIMITATIONS ARE AROUND SRM

·         Still Growing into large enterprise solution
