3.1 Options and Replaceable Components

Sun Storage J4500 Array Replaceable Components  lists the after-factory options and replaceable components for the J4500 array. All parts are customer-replaceable units (CRUs).


Note - The J4500 array is shipped from the factory with drives of the same capacity. Mixing drives of different capacities in the array is unsupported. When ordering a replacement drive, ensure that the disk subcomponent of the CRU conforms to this rule.


Devices described as hot-pluggable may be replaced without requiring a reboot of the host computer or the array, however the device being replaced first needs to be shut down or isolated by the operating system to prevent host access during replacement. Devices described as hot-swappable may be replaced without any kind of system preparation, reboot or shut down.

Supported components and their part numbers are subject to change over time. For the most up-to-date list of replaceable components, product updates, and downloads, see the following URL:
