Cat Herding Why It s Time for a Millennial Approach to Storage Cloud Expo East 1
A Time and Place for Everything The PC Movement of the 1980 s put pressure on mainframe storage architects In 1987 the RAID Papers were released The dawn of capacity HDD was born Higher density begets greater failure potential Boy, has the world changed 2
The Evolution of Storage: 20 th Century Thinking RAID served the enterprise but it was expensive Opex baggage was dragged along to help manage the enormous complexity Every Data Center standard on the planet was improved upon to support the growth of data CATS It was like herding cats.and then came the internet and cloud-scale
The Cloud of Things The 21 st Century brought the Millennials into the market Always on and always Up At Scale Facebook, Amazon, Yahoo, Google, Twitter, Linkedin developed a new approach to do everything Traditional Storage could not keep up Object Storage enters the Fray 4
Comparison of Storage Technologies SAN Scale-out NAS Active Archive Why it Matters Type Block File Object Exascale archival data stores demand freedom from the scale limitations of a file system hierarchy. Data Management LUN Carving Mount Share None LUNS require application-stack data management which places a high burden on the administrator to manage resource pools. Active Archive has a global namespace that scales with data growth without any need to reconfigure data paths. Metadata None Some Rich Unlike traditional file system metadata schemas that present a one size fits all model, object stores provide for a unique userconfigurable metadata schema per object with no relationship to or dependency on any other object in the same namespace. Scalability ~2PB ~4PB Exabytes A long term archival system needs to scale with data growth Multigeography No Replicatio n Dispersal Without geo-dispersion of data, it requires a full DR strategy to ensure no data is lost. This will double the cost of the infrastructure Consistency N/A Eventual Immediate Immediate consist data ensures that data is safely stored off site as soon as it is written, eliminating vulnerabilities that can occur due to replication time lags. 5
Comparison of Storage Technologies Site failure tolerance No SAN NAS Active Archive Requires DR site Data Protection RAID 5,6 RAID 6,10 Yes Erasure Coding Why it Matters People s expectation of the cloud is that it is always available from anywhere Traditional RAID requires full disk drive rebuilds. As disk drives get larger, RAID rebuilds grow such that a second drive can fail. With erasure coding there is now downtime and it is self-healing Disk Overhead 167% 167% 59% Erasure coding provides far greater datacenter efficiencies in power usage, footprint, cooling and drive maintenance Cost per GB (no DR strategy) $0.30- $3.00 $0.50- $1.00 $0.18 (List) Object Storage provides industry s best TCO for large scale private cloud. Storage Density 82TB/RU 45TB/RU 112TB/RU Massive savings on floor space compared to NAS or SAN Power Density per Watt 0.43GB 0.21GB 0.62GB The Active Archive System is significantly more power efficient as it utilizes HGST helium drives. Data Durability 6 9 s 6 9 s 15 9 s Bit Rot can cause data loss over time. HGST Active Archive has the highest data durability. 1000 times more reliable than the public cloud. Drive fail-inplace No No Yes up to 5 Cloud infrastructure is built with the expectation that drives WILL fail and that should not be a major cause for concern. Instead of being a critical issue, drive failure becomes standard maintenance 6
