2. 内容安排 WHY: today we're going to talk about cloud storage? WHAT: you understand cloud storage? HOW: to help users build cloud storage? WHEN: moment to talk about the cloud storage? WHO: faced with a different user, you should talk about the cloud storage？ 2 戴尔机密
4. 企业愿景、使命与策略 4 戴尔机密 什么是云存储？ Cloud storage in the cloud computing (cloud computing) conceptually extended and developed a new concept. Cloud computing is a distributed processing (Distributed Computing), parallel processing (Parallel Computing) and grid computing (Grid Computing) development, through the network will be a huge computing handlers automatically split into numerous smaller subroutines, then handed over to the server through an extensive system of calculation of the results of the work after the return to the user. Adoption of cloud computing technologies, network service providers can within seconds, the processing of millions or even billions of information, meet and "super computer" equally powerful network services. Cloud storage concepts and cloud computing are similar, it refers to the application through clusters, grid technology or distributed file system and other functions, in the network all the different types of storage devices through software applications work together, common external provides data storage and business access features of a system. 云并不是一种产品 云是一种构架 云是一种服务

“Dell EqualLogic” can be positioned as the key component into Dell “Cloud Storage” framework with the following 7 key characteristics (unique values of Dell Cloud Storage): · Cloud Addressing – almost unlimited addressing scalability:· We support IPv6 natively on both management, applications and iSCSI initiator level (unlike other storage solution which only support IPv6 on management port only)· Cloud Transparency - Location transparent (virtualization):· Path virtualization - can make the actual location of the resource/volume transparent into the Cloud and when we move the volume and array to other location, the server can automatically follow· Location Virtualization - able to join multiple storage arrays together into the cloud and essentially make the location less sensitive· Resource Virtualization - volume can automatic place into multiple arrays and with build-in data cloning and replication, we can easy make the data move from one place to another and yet enjoy increase performance benefit· Cloud scalable performance - linear performance scalability:· Storage array can be online added into the cloud to make the “Storage Cloud” stronger and bigger and can be easily scale back online to provide the ultimate flexibility in the infrastructure· Cloud Load Balancing - Automatic Performance Load Balancing – dynamic workload balancing:· Automatic transparent network load balancing make the cloud storage infrastructure be able to scale with the loading· Cloud Storage virtual capacity - Capacity virtualization:· Our high flexible Thin Provisioning feature can make storage sizing control much more flexible – easily allocated and take back the pre-allocated space, and this feature work within the cloud either locally or remotely (Thin Replica)Cloud level Data protection without performance impact:At the end of the day, no matter how strong is the cloud, data simply can’t loss and yet performance need to be guaranteed, “Dell Cloud Storage” can deliver the promiseCloud-wide MonitoringWe will offer the total visibility into Cloud Storage management – operation and performance wise using our upcoming SAN-HQ, this make the move to the “Cloud Storage” easier
