[1] Installation from one GUI, Management from different GUI’s
[2] EMC delivers RAID 6 but with performance penalties
[3] Without the ability to shrink volumes
[4] Celerra Replicator for NAS/iSCSI, MirrorView for FC, Recoverpoint scheduled for release Q4
[5] NS-120 w/ 2 Data Mover, NS-480 up to 4, NS-960 up to 8. One Data Mover is passive for failover
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
