VMAX FAST VP

Jump to solution

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,

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.

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,
