Linux 2.4内核限制

Posted by: JiaLiang Liao 16 years, 5 months ago

前几天在做项目的时候，碰到服务器内存超过4GB时，最多只能认出4GB内存的问题。在解决之后，想了解一下Linux 2.4内核究竟最多能支持多少个CPU、内存和文件系统的限制。

通过查资料，得到以下结论：

CPU

最多能够支持32个CPU。

Swap

最多能支持8个Swap分区，RHEL2.1版本每个Swap分区最大为2GB。

Memory

默认安装的内核只能支持最多4GB内存，大于4GB的内存只能认出4GB。通过重新编译内核添加HugeMemory支持，可以支持超过64GB内存。

EXT3

单一文件大小上限为2048GB(与操作系统有关，最好单个文件不要超过4GB)，文件系统的容量上限为6384GB。
