RSS概述

阅读更多关于 RSS概述

RSS概述信息聚合（也成为内容聚合），是目前网络中一种非常流行的技术，它将用户所关心的Web内容聚合以后，通过客户端软件提供给客户。这些由内容服务商提供的信息或信息描述——称为feeds可以包含从标题、摘要、链接到剥离了布局结构的完整的网站内容等等不同层次的信息。 RSS的处理模式其实RSS并非全新的技术，它是建立在人们对信息推送技术深入研究的基础上。一般来说，一个分布式信息系统由三部分组成：信息源，它提供用以传送的数据；客户，即信息用户；信息代理，它从信息源处获取信息，或将信息发布给其他信息用户。正是信息代理为我们提供了信息推送(push)和信息拉取(pull)技术的粘合剂。传统的信息代理(如因特网浏览器)是完全基于信息拉取技术的, 它根据用户非周期性的请求(request)到信息源处拉取信息。而在 RSS 中, 作为信息代理的媒体聚合器(Agrregator)则集成了信息拉取和推送两种技术;根据用户最初的信息需求定制, 它周期性地到信息源提供的信息摘要(称为 RSS feed)处拉取相关信息, 并将这些摘要信息推送到客户的桌面, 客户也可通过聚合器提供的链接访问其所关心的详细资料。可见 , 我们并不能简单地RSS 是基于信息推送技术的, 因为 HTTP 协议主要是基于信息拉取的, 所以 RSS 是 push和 pull 两种技术共同协作的产物。 RSS的具体工作方式

当存储EVA出现故障这种方法可高效解决数据丢失的情况

阅读更多关于当存储EVA出现故障这种方法可高效解决数据丢失的情况

【EVA存储设备信息】 1、HP EVA8400存储：1组扩展柜。 2、12个2T FATA磁盘（AG691A 454414-001）和8个300G 15K FC磁盘（AG690A 454411-001）组成。 3、主机环境为WINDOWS。【EVA存储故障分析】 1、经与用户再三确定得知，数据出现故障后已停止使用。按照以往HP-EVA的故障可能推断，数据恢复的可靠性较高。 2、EVA主机及扩展柜正常关机，之后将所有硬盘标好位置序号，拿出。在数据成功恢复之前，不再开启EVA 8400控制器。 3、接手磁盘后，按照相应链路对磁盘进行连接。 4、进入WINDOWS环境，用WINHEX查看磁盘情况，发现所有磁盘均可正常识别。 5、查看每个磁盘信息，发现300G FC磁盘存在PV HEAD，而1T FATA磁盘上均无PV HEAD。查看300G磁盘中存储的Metadata，发现仅描述了一个RSS组组成的LUN,大小不足2T，成员为所有300G磁盘。而1T FATA磁盘中残留的LUN信息则至少包括5组信息。上述信息表明，某种原因导致删除了1T 磁盘组成的DISK GROUP内所划分的所有VDISK，并UNGROUP了所有1T FATA磁盘。 6、分析1T FATA磁盘上保留的Metadata。【EVA存储故障恢复过程】 1、对所有磁盘做完整镜像。 2、对300G 磁盘所属的LUN进行恢复
