Ds300 Model 1701-1Rs - IBM TotalStorage DS300 Best Practices Manual

Attention: It is theoretically possible to upgrade the DS300 Model 1RL to a
dual controller model. The already installed controller would have to be
replaced (because FRUs do not come with the cache memory and battery
backup cache), and a second controller would have to be installed along with
a second power supply.
However, this upgrade option is not offered and not supported. In addition, this
upgrade would cost more than purchasing a dual controller model!
