SSD Application - DatacenterSSD Application Datacenter
• Major 3 benefits of SSD in datacenter
Less Power• SSD consumes less power due to no mechanical part• SSD has high power efficiency because of high performance• SSD has high power efficiency because of high performance• Datacenter reduces power consumption enhancing service
Less CoolingLess Cooling• SSD emits lower heat because of no moving part• SSD operates in higher temperature band• Datacenter decreases cooling cost despite of more work• Datacenter decreases cooling cost despite of more work
Less Space• SSD outperforms HDD over 100 timesp• SSD treats more much data due to high performance• Datacenter works more without additional warehouse
Tech Trend: Sustained PerformanceTech Trend: Sustained Performance
• Push for sustained performance– Sustained performance means supporting stable service
without fluctuation– FW optimization, over-provisioning and super-cap technology
keep improving end user experiences by enabling sustained performance

Tech Trend : Infra CollisionTech Trend : Infra Collision
• System infra has been fit to HDD so that SSD has infra lli i ith t i fcollision with current infra
– For instance, current RAID/HBA controller cannot show full SSD performance due to hardware limit
• Need close work with RAID/HBA vendors to maximize SSD performance
