ControllerFirmware:ControllerNVRAM:N1815D480R923V09随机访问比较多的应用划分磁盘时建议做RAID0+1，顺序访问的应用做RAID5;访问量比较大的LUN均衡到多个RAID组中，避免热点盘过于集中；尽量分配同一容量的LUN,对于同一机器的不同属性的应用（DB/FS）,可分配不同容量的LUN;数据空间跟索引空间建议放在不同的RAID组中，数据放在RAID5中，日志放在RAID10中;对于HP需要做MC的双机，分配一个容量为100M的LUN作为锁盘；在主机端认到PV后，将PV与LUN、LUN与Host之间的对应关系作成表格交予系统管理员，以利于主机做条带化；针对多应用的情况可以来自于不同的RAID组。IP地址根据网络地址规划，为DS480S配2个主IP地址：ControllerAIP:（默认值：BIP:就认值:与扩展单元的连接规划1个DS480价口8个扩展单元-Recommendedcabling1个DS480阱口1好EXP810r展单元一Recommendedcabling注：新增A:含7个EXP810根据连线规则A的方式连线新增B:含10个EXP810根据连线规则B的方式连线新增C:含12个EXP810根据连线规则B的方式连线新增D:含13个EXP810根据连线规则B的方式连线磁盘大小规划与主机名规划IBM工程师将根据客户提供的主机分配表为您规划磁盘，并分配到相应的主机。您能通过该主机名来指定与规划出的磁盘的对应关系，
