Preparing Shared Storage 21
d First sector (63-xxxxxx, default 63) : <Stripe
Element Size or Segment Size in terms of
Sectors>
Where the Stripe Element Size (SES) or the Segment Size (SS) is the
amount of disk space that is consumed on a single physical disk by a
Stripe Element as part of Stripe.
For example, a stripe that contains 256 KB of disk space and has 64 KB
of data residing on each disk in the stripe. Here the stripe element size
is 64 KB and the stripe size is 256 KB.
Use the following formula to set the value above:
Stripe Element Size in Sectors = Stripe Element Size in KB * 2 First
Sector = Stripe Element Size in Sectors
NOTE: The above formula assumes that 1 Sector = 512 Bytes or 0.5 KB.
Set the above value to the following, if the SES/SS was left at the Storage
Controller’s default value:
– For Dell PowerVault MD30xx/MD30xxi, set First sector to: 128
(default 64 KB * 2)
– For Dell PowerVault MD32xx/MD32xxi, set First sector to: 256
(default 128 KB * 2)
– For Dell EqualLogic PS-Series, set First sector to: 128 (default 64 KB * 2)
If the SES/SS for the disk/Volume/VD is set to a non-default value of the
storage array, for example 512KB in case of MD32xx, set the First sector
value to 1024.
Last sector or +size or +sizeM or +sizeK (1024-xxxxx, default xxxxxx):
<Enter default value or return key> # Default Value so the single
partition spans the entire disk
Command (m for help): wq # write and quit
