Enclosure variants
The 2U chassis can be configured as a controller enclosure ME4012/ME4024, or an expansion enclosure ME412/ME424 as
shown in 2U12 enclosure variants and 2U24 enclosure variants. The 5U chassis can be configured as a controller enclosure
ME4084 or an expansion enclosure ME484 as shown in 5U84 enclosure variants.
NOTE:
The 2U and 5U core products—including key components and CRUs–are described in the following sections. Although
many CRUs differ between the form factors, the controller modules and IOMs are common to 2U12, 2U24, and 5U84
chassis. The controller modules and IOMs are introduced in 2U enclosure core product and cross-referenced from 5U84
enclosure core product.
2U12
2U12 enclosures consist of 12 x LFF (Large Form Factor) disk drives and 12 x HFF (Hybrid Form Factor) disk drives.
