Question about sff vs lff chassis

[zdawg]

Specifically I was asked about the DL380p Gen8 8-LFF chassis vs. the DL380p Gen8 8-SFF chassis.  I know that the lff = large form factor hard dri ve cage, and sff = small form factor but what are the advanatages/disadvantages of each?

Is it simply that with a sff cage you have room for more drives?  Or is it more complicated than that, as I assum the servers themselves are the same size.  

Thanks

Hi,

It literally is about how many drives each one can store.  

LLF means youcan utilise the capacity & cost gains that large form factor SAS/SATA offers & SFF means you can get more performance as you have more avilable spindles.

Thats really about it

Hope this helps

Also, look into the CTO chassis that haven't been promoted much. By ditching the [useless] optical drive you can get 10SFF DL360p G8 and 25SFF DL380p G8. Way better than only being able to put 8 disks in an HBA RAID volume, especially when using triplex mirroring.

There are also 4LFF and 12LFF models respectively, for those who like the larger disks.
