choice none data protection level on a lefthand p4000 -less performance ?

hello

i have two nodes and i am oblige to wait 6 month before having 2 others

 

I need to create a volume, i have enought space if i didn't use the option two ways for data protection level

 

will i lose performance if choice none rather than 2 ways ?

 

thanks a lot

Hi,

 

Netzork RAID 0 will give best performance and available disk space but you will loose data and/or downtime if you loose one of the storage nodes...

 

That is why network RAID 10 is the best solution...

do you need the full volume size right now?  if not, you can always creats the LUN w/ raid10 at 1/2 the size and then increase the size when the rest of the hardware comes in.

Escuse me just a confirmation

 

when you say raid0 you mean, none data protection ?

 

because for me it isn't the same

 

On each node i have RAID5 for the disk

Each time i creat a volume i make it with data protection onthe 2 nodes

 

My question was to gain space without loosing perf, if i deselct the option in data protection

 

thanks

Hi,

 

On hardware level you always have RAID5 as a start... You can change this in RAID6 or RAID10 afterwards if you want. Almost everyone keeps it in RAID5...

 

On top of that you can implement network RAID10 which means that the data blocks are written on at least 1 storage nodes... If you set this to network RAID0 (which is the same as no data protection), the data blocks are striped accross the 2 storage nodes... Which means you loose data if you loose a node...

 

You can also start with smaller volumes to save space and expand the volumes later? Or start with a thin provisioned volume? Then it only takes the data blocks really needed and not the initially wanted volume size.

Hey
i cannot start with small volume

thanks for your explanations now it is clear for me

have a nice day
