Sun Directory environment generally isn't very IO intensive, except for in massive data reloads or indexing operations. Other than this it is an ideal candidate for ZFS and it's rather nice ARC cache. Memory is cheap on a lot of boxes and it will make read only type file systems fly. I imagine your actual living LDAP data set on disk probably won't be larger than 10 Gigs or so? I have around 400K objects in mine and it's only about 2 Gigs or so including all our indexes. I tend to tune DS up so that everything it needs is in RAM anyway. As far as diectory server goes, are you using the 64 bit version on Linux? If not you should be as well.
From my experience enabling lzjb comprssion for DS makes it even faster and reduces disk usage by about 2x.
