Hello we are NetApp marketing professionals
don't do this at work
Hi I'm Mark Henderson
and I'm Mark Phelan
and were here to talk to you about some worry-free technology from NetApp
called dynamic dispools
it's a new way of doing storage
which helps with performance efficiency and scalability
now what we've just done
that you shouldn't do at work
is we've caused two systems a double drive failure
yep it's not a very nice thing to do
and of course if your storage admin then you're probably thinking were a little crazy
so what we have here today are two systems
the top system here is running your traditional RAID 6
so its 22 drives in the RAID 6 plus 2 idle spares
and on the other e2600 system
were running dynamic disk pools
what that means is you got again 24 drives
well except for the ones we pulled here
and there all functioning in a single pool
now the RAID system
there both trying to recover from guys pulling drives
the RAID system is trying to rebuild itself as a 22 drive RAID system
dynamic disk pools says well I was at 24
missing a couple of drives yep
oh dynamic re balance to 22
so we've scaled this for purposes of this video
so we've got what 50 GB volume
like what Mark was saying we've scaled this down
because well a 3 terabyte drive in a traditional RAID 6 system
is going to take about well 4, 4 and half days to rebuild
and frankly we don't want to stand here for 4, 4 and half days
yeah, and doing this same sorta 3 terabyte drive in a dynamic disk pool system
would be rebuild in about 18 hours
big difference, huge difference, however we are not going to stand here for 18 hours either, yeah
now reality, you know this thing has been working
its been dynamically rebalancing all the data, Yep
could we pull another drive at this point?
I think we can
alright lets go for it, okay
so, 3 drives gone out of the dynamic disk pool system
you'll see we take a temporary performance hit
and then it will come back up
and continue on its way
its going to rebalance that information that data that was pulled
across all the remaining drives
so were constantly just taking the system
and rebalancing that so that all the drives are used in the most efficient manner possible
so what if we took 3 drives out of the RAID system
I think we all know whats going to happen there
what happens there is your looking for back up tapes
yeah your scrambled at this point
yeah back up tapes are bad
but the reality is your not going to be taken 3 drive failures, no
no, not in a normal environment
mostly what your going to do
is your going to take your systems and your going to want to expand them
your going to grow
so you'll add capacity
that's right
with dynamic disk pools you can add a single drive
you can add up to 12 drives at a crack
yes
and its really easy
super easy actually
so I've got this system here setup with 24 drives
if I were to add an additional chassis here
I could go into my management interface
and the system automatically goes out and has recognized
that there is additional drives available
and all I have to do
the system asks do I want to include those additional drives
in my existing dynamic disk pool
all I have to do is say yes
and all of those spindles available will be inserted into my existing dynamic disk pool
so you don't have to configure RAID sets
there's no RAID sets, there's no, it is super efficient
and its the scalability of this system is phenomenal
I mean right now we are running an e2600 system, yep
this can scale to 192 drives in a single pool
and the e5400 can scale to 384 drives
and all those can be in a single pool
contrast that to your traditional RAID 6 system
which is limited to 30 drives
in a single RAID pool
so I get a lot more performance out of this system
cause I'm able to take advantage of all those spindles working for me
that's, that's perfect
yeah
so, again its rebalancing
it's doing this for performance, efficiency and scalability
so could we pull a 4th drive at this point
let's go ahead and pull the 4th drive
alright
4 drives out of dynamic disk pools
it's now going to rebalance itself
as a 20 drive system
and go on its merry way
yeah, sure
so E series enables bigger science faster and more efficient
Thanks for watching
this is Mike and Mark
take care
have a good day
