Symmetrix V-Max
Enginuity Code: 5874
Includes EMC Symmetrix V-Max and various different configurations within this model.
GB = Cylinders * 15 * 128 * 512 / 1024 / 1024 / 1024
Eg: 262668 Cylinder device equates to 240.47 GB of usable data
262668 * 15 * 128 * 512 / 1024 / 1024 / 1024 = 240.47 GB
Cylinders = GB / 15 / 128 / 512 * 1024 * 1024 * 1024
15 = tracks per cylinder
128 = blocks per track
512 = bytes per block
8 bytes = 520-512 used for T10-DIF
1024 = conversions of bytes to kb to mb to gb
Drive format on a V-Max is 520 bytes, out of which 8 bytes are used for T10-DIF ( A post on DMX-4 and V-Max differences).
