这里涉及到两个知识点,一是SQL server 对GUID列的排序算法实现,二是Cluster Index和NonCluster Index的区别。先说一下SQL Server对GUID列的排序是如何实现的。具体文章在这: http://blogs.msdn.com/b/sqlprogrammability/archive/2006/11/06/how-are-guids-compared-

SQL Server isn't as tightly integrated with Pacemaker on Linux as it is with Windows Server failover clustering (WSFC). A SQL Server instance isn't aware of the cluster, and all orchestration is from the outside in. Pacemaker provides cluster resource orchestration. Also, the virtual network...
An Always Onfailover cluster instance(FCI) is a SQL Server instance that is installed across nodes in a WSFC. This type of instance depends on resources for storage and virtual network name. The storage can use Fibre Channel, iSCSI, FCoE, or SAS for shared disk storage, or use locally at...
To upgrade a SQL Server failover cluster instance, use SQL Server setup to upgrade each node participating in the failover cluster instance, one at a time, starting with the passive nodes. As you upgrade each node, that node is left out of the possible owners of the failover cluster insta...
To install a failover cluster, you must use a domain account with local administrator rights, permission to log on as a service, and to act as part of the operating system on all nodes in the failover cluster. To install a failover cluster by using the SQL Server Setup program, follow...

在每个 node 里,它包含一个或更多的 shards。这些 shards 可以是 primary shard(主分片),也可以是replica shard(副本分片)。每个 shard 里含有一个 index 的全部或部分数据。一个 index 由一个或多个 shard 组成。每个 index 包含无数的 documents。每个 document 时间上是由相同的属性的 JSON 文档组成的。
