if we had a server with big diskspace, function build_vol_hash_table cost
to much to build the vol_hash_table for CacheVol
**if the Volume space is 50TB, the rtable_size will be 50* 1000 * 1000 /
8=6250000,it cost too much memory and cpu usage( see the code in
build_vol_hash_table listed below), maybe we need to optimize this
build_vol_hash_table function.**
rtable_pair *rtable = (rtable_pair *)ats_malloc(sizeof(rtable_pair) *
rtable_size);
int rindex = 0;
for (int i = 0; i < num_vols; i++)
for (int j = 0; j < (int)rtable_entries[i]; j++) {
rtable[rindex].rval = next_rand(&rnd[i]);
rtable[rindex].idx = i;
rindex++;
}
