11 4. Feature

12 4. Feature 1. Business continues even if failure occurs Detect system failure and execute failover for business continuity Case: Single configuration Case: Cluster system Service anomaly Network disruption Network disruption Failover Application On-premise Cloud Service anomaly Active HW crush HW crush Data center System stops until server recovery Business stops until maintainer arrives System is not fully protected even operated in cloud or datacenter Lose business opportunity Lose credibility of a company Server operation is ensured with both on-premise and cloud environment without anxiety *It takes over IP address while connecting session is disconnected Another server automatically takes over the business application and data Redundancy is crucial in case of cloud and datacenter as well Minimize the loss of business opportunity Company operates system without anxiety 12 NEC Corporation 2016

13 4. Feature 2. Business continues even when planned maintenance System operation does not stop by being maintained by turns *1 Cause for system stop 1 Application 9%: OS / driver panic 6%: Application error 5%: Hardware failure 4%: Other failures Stop due to failure 24% Application Active Maintenance Application 2 Planned maintenance 76% Single server Active Move Move Active 37%: OS upgrade / OS restart by service pack & hot fix application 13%: Application installation / application maintenance 12%: OS restart to reflect OS setting change 7%: OS restart to enable new HW connection and setting 7%: OS restart by other reasons 4 Application Active (Reference: June 2005, Microsoft. Windows Server 2003, EE reliability document Maintenance 3 13 NEC Corporation 2016 *1: With clustering, only application move time is required instead of whole maintenance time.

16 4. Feature 5. Protect data from failure Protect important business data from any failure or disaster With snapshot, data can be recovered from past disk image Application Application Active Stand-by Mirror volume 転送 Update history Convert Snapshot image Update history Snapshot image Data can be mirrored within several servers, enabling failure resistance Application Application Application Active Stand-by Stand-by Mirroring (Synchronization) Mirroring (Asynchronization) 16 NEC Corporation 2016

17 4. Feature 6. Business continues in case of disaster Earthquake, fire, electric outage cluster enables business continuity from any disaster Remote cluster as a measure for disaster Cause of business stop is not only HW/SW failure. In case of disaster, automatic failover to stand-by server in backup site is executed. With the industry s first *1 intelligent mirroring to dynamically & automatically switch mirroring method based on communication status and quantity of differential data, EXPRESSCLUSTER D flexibly supports unstable network between remote sites.

23 6. Various Operation Models

24 6. Various Operation Models Active Standby Failover Active Active (Dual-directional standby) Failover Active On demand standby Failover Active Standby Active Standby Standby Active Active Standby Failover Mirroring (object mirror) Mirroring (object mirror) Cloud The most popular cluster model Most business system can be applied to this cluster model If any failure occurs in the active server, failover is done to the standby server Cluster scale can be expanded to more than 3 servers, such as Active- Standby-Standby By operating different system in each server, cluster operation of dual-directionally Active / Standby is enabled If any failure occurs in one server, failover is done to another server Load will be increased when failover happens as two business systems are managed in single server Starting time of standby server is minimized by linkage with the cloud storage, which reduces the operation cost as well (more detail is on 3. Feature 3Reduce managing cost with Cloud) 24 NEC Corporation 2016

25 6. Various Operation Models Active Standby Failover Active Active (Dual-directional standby) Failover Active On demand standby Failover Application Application Application Application Application Application Active Stand-by Active Stand-by Stand-by Active Active Stand-by Failover Mirroring (Object storage) Mirroring (Object storage) Cloud Most popular cluster type Most of application service can be clustered with this type When anomaly is found in active server, failover is done With more than 3 servers, expanded config (such as active - active - stand-by) is enabled N:1 stand-by configuration is enabled to avoid high server load of mutual stand-by config By operating different application in each server, mutual active - stand-by cluster can be configured Failover from server in failure situation to the other server In case of failure, one server has to operate two application VPN With object storage, stand-by server operation time can be minimized leading to the cost reduction (Detail is in 4. Feature 4. Reduce managing cost with Cloud ) 25 NEC Corporation 2016
