The Adaptec Raid 5405 Supports A Broad Range Of Operating Systemsadvanced Data Protectionadaptec Raid Code (Arc) Delivers Maximum Reliability With Raid Levels 0, 1, 1E, 5, 5Ee, 6, 10, 50, 60 And Jbod. Arc Also Offers Raid Level Migration (The Ability To Easily Migrate Raid Levels), Online Capacity Expansion (Expand Capacity Without Powering Down The Server), And Copyback Hot Spare (When A Failed Drive Has Been Replaced, Data Is Automatically Copied From The Hot Spare Back To The Restored Drive). Hybrid Raidwith Hybrid Raid 1 & 10 The Series 5 Controllers Offer Maximum Performance And Reliability By Combining Solid State Drives (Ssds) And Hard Disk Drives (Hdds) In A Single Array. By Performing Read Operations From The Faster Ssd And Write Operations On Both The Ssds And Hdds The Result Is Tremendous Performance Gains Over Standard Hdd Raid Arrays. Hybrid Raid Offers The Benefits Of Both Technologies And Allows A Better Cost Per Gb Ratio Than Comparable Ssd-Only Raid Arrays. The Case For Cachethe Fastest Way For A Raid Controller To Fulfill A Read Or Write Request Is To Serve Data Out Of Its Cache. Enabling The Raid Controller Cache Offers Significant Performance Benefits, Such As Reduced Latency In I/O Requests, Bandwidth And Queue Depths That Surpass Software Application Limits, And On-The-Fly Parity Calculations On Sequential Writes. Intelligent Power Managementthe Power Required By Disks Is A Primary Ongoing Storage Cost. Full Power Is Maintained To Every Disk Whether It Is Actively Being Used Or Not, Which Also Increases Cooling Costs. Adaptec Intelligent Power Management Slashes Power And Cooling Costs By Spinning Down Idle Disks And Providing A Lower Power Mode For Active Disks.
