Hi,
I wanted to get opinions on advantages and disadvantages of using LSM in a configuration where we will be using HSG80s to provide mirror pairs to the OS. LSM would not be used for mirroring and there would be no DRL configured either. All LSM would do is "manage" the disk (unit) in its own disk group and create one volume from that disk that was the same size as the whole disk.
I am having trouble seeing the benefit of using LSM in this configuration, but I thought someone could open my eyes to whatever I may be missing. In fact, I thought that going through the LSM driver stack would likely degrade performance by a couple of percent overall (we have many disks, disk groups, volumes on our system).
I'm ready to hear any opinions! Thanks.
