VMAX FAST VP
We are using FAST VP on a vmax 20k and have the 3 std thin pools - efd, fc and sata. the FC is Raid5 with FAST VP policy utilizing all three thin tiers
We want to add a Raid 1 FC pool and create a new policy that utilizes the efd, FC-R1, and sata.
In addition, the FC-R1 pool will consist of same rotational speed drives but different sizes - this pool would consist of 450GB FC 15K drives.
the FC-R5 pool consists of 600GB 15K drives.
is this supported? we are on 5876 code.
Thanks.
Jim

Hi Jim,
Yes, this is supported.
FAST VP on VMAX 10k/20k/40k doesn't differentiate between FC RAID1 and FC RAID5, but since you're creating separate policies for your two FC pools/tiers (rather than trying to put both the FC R1 and R5 tiers into the same policy), this is fine.
Thanks,

Jim,
That's correct -- a thin pool can only belong to a single VP tier.
The new FC RAID1 pool should consist of a new/unique disk group, pool, and tier, and should be in a new policy. You can share the existing EFD and SATA tiers in the new policy that contains the new FC RAID1 tier.
Thanks,
- Sean

all I read is that a thin pool can ONLY belong to a single VP tier. I found that limitation in a 2012 and 2014 release of P/N 300-012-014.
We would be using the efd and sata pools in two different tier configurations.
