DS3500 Express
Offers substantial performance and functionality starting at entry-level prices
Building the DS3500
START with the DS3500 // Four 6 Gbps SAS host connectors in a dual controller configuration
• Cost-effective high performance storage for up to two direct-attached servers in a Highly Available configuration
• Connectivity to redundant 16-port SAS switches supports up to eight servers in a Highly Available configuration
• Provides booting and shared storage for IBM BladeCenter
®
DS3524 – Best fit for environments requiring highest performance, best price/performance, or lowest power/cooling
DS3512 – Best fit for environments requiring highest capacity, or a high capacity/high performance blend
Add a host card to expand SAS connectivity or support additional interface technology
SAS host card – adds two more 6 Gbps SAS host connectors per controller
• Further expands shared DAS or networked capabilities with support for eight SAS connectors (dual controller)
• Interface of choice for low cost, high performance “in-the-rack” connectivity
FC host card – adds four 8 Gbps FC host ports per controller
• Seamless integration into existing FC SAN implementations for workgroups, departments or remote sites
• Supports enhanced remote mirroring between DS3500 systems, or with DS5000, DS4000 and/or DCS3700
iSCSI host card – adds four 1 Gbps or two 10 Gbps iSCSI host ports per controller
• Simple and straightforward IP SAN solution that’s well suited for low-cost storage networking requirements
• 10Gbps iSCSI interface provides native connectivity into high-performance IP SAN infrastructures
• Enables use of low-cost IP based disaster recovery solutions with new premium feature key
Add an expansion unit to increase capacity or performance
• EXP3524 for maximum performance; EXP3512 for maximum capacity; or intermix as needed!
Mention DS3500 storage when your customers
