About this book
This guide describes the EMC
®
VNXe3100™. The VNXe3100 platform supports a disk
processor enclosure (DPE) with one to two storage processors (SPs).
In a single SP configuration, a Cache Protection Module is provided. This Cache Protection
Module is used in the event of an outage. The data in the VNXe3100 platform write cache
is safely stored in the Flash memory of the Cache Protection Module, eliminating
time-limited battery backup and external power supplies. The Cache Protection Module
capacity is 1 GB.
In the VNXe3100 platform, the DPE uses a 12 drive, 3.5-inch disk 2U enclosure. The DAEs
in the VNXe3100 platform use either a 12 drive, 3.5-inch disk 2U enclosure or a 25 drive,
2.5-inch disk 2U enclosure (DAE5S).
Note: The 2U 25, (2.5-inch) disk drive DAE is only supported when you have VNXe
Operating Environment (OE) software version 2.3.x and above installed.
In a dual SP configuration, a 2U, 12 drive (3.5-inch) DPE and DAE can support up to seven
2U, 12 drive (3.5-inch) DAEs, thus supporting a maximum of 96 disk drives
.
In a dual SP
configuration, a 2U, 12 drive (3.5-inch) DPE with a 2U, 25 drive (2.5-inch) DAE and a 2U,
12 drive (3.5-inch) DAE, the configuration can support up to three 2U, 25 drive (2.5-inch)
DAEs and one 2U, 12 drive (3.5-inch) DAE, thus supporting a maximum of 99 disk drives.
In a single SP configuration, a 2U, 12 drive (3.5-inch) DPE and DAE can support a
maximum of three 2U, 12 drive (3.5-inch) DAEs or 48 disk drives. In a single SP
configuration, a 2U, 12 drive (3.5-inch) DPE with a 2U, 25 drive (2.5-inch) DAE and a 2U,
12 drive (3.5-inch) DAE, thus supporting a maximum 49 disk drives.
