Exadata upgrade to Fourth Rack from Eighth Rack

当初出现1/8配,1/4和1/8硬件配置是一样的(从X6-2开始,1/8和1/4的硬件是不同的,表现在存储节点磁盘数量和闪存盘的数量减半),对客户来说既能满足需求,也不需要花费太多的费用,对Oracle来说既能扩大市场份额,如果升级还能带来一部分收益。在中国买1/8配置的客户还是挺多的,通过脚本能查看当前的配置和激活的资源,在X4,X5从1/8升级到1/4还是比较容易的,硬件没有变化,方法也有多种,在X6-2中,1/8比1/4的硬盘和闪存数量减一半,如果扩容需要重新购买硬件资源。


Extending Oracle Exadata Database Machine X4-2 or X5-2 from an eighth rack to a quarter rack is done using software. No hardware modifications are needed to extend the rack.

However, hardware modifications may be needed for Oracle Exadata Database Machine X6-2. See For Oracle Exadata Database Machine X6-2: Adding High Capacity Disks and Flash Cards for details.
