Dell Precision Poweredge 7910 Raid recovery query

[higgsboson]

Dear friends
I have got this device It has SAS drives in Raid 5 configuration. I have go success with recovery part and Data is verified and approved as well.
Now I am facing problem how to copy this data due to its size ( 10 TB with 3.9 million files)
Can someone pls. give some Idea how I can I copy data ? Attached is snap of the tower. It is having mini 4 port SAS controller. But no additional SATA power /ports etc. Is there any option to add pci express based SATA card as tower has pci /pci express slots besides 2 gigabit ethernet ports. Manual lists 2 SATA ports but I could not locate them.
Another concern is I am booting workstation using winpe with limited drivers. So drivers should not be the problem.
Any suggestion who has already done recovery of such models.

Looks like something is plugged into the sata - white and black vertical ports on the bottom of the motherboard - follow the cables.

Either connect the destination via USB3, disconnect something not in use DVD? or just slap an extra sata adapter in and use a few power splitters.

Just curious, the machine just boots from live systems? So you didn't remove the drives for recovery?
Thanks.

I believe the OP is in India and has a less "formal" DR set up.

Grevan , Its not necessary to remove disks from this case (and in general from every case , It depends upon case to case and if situation demands)
In this case there is simple logical corruption which can be fixed by Live System Booting. Then why to remove disks and make it more complicated ?

Country of origin might be immaterial. here is law of efficiency as well .What kind of formal setup is needed for a case which can be fixed by a single bootable pen drive ? Not all cases need imaging ,it depends upon case to case , cost approval etc.
Hope you now understand other aspect of the case.

It is best practise and industry standards to image all cases.

Not all cases need imaging ,it depends upon case to case , cost approval etc.

These are business reasons not data recovery ones, attitudes towards these reasons and the risks involved varies greatly geographically, as such country of origin does matter.

Should you wish to work live and your customers agree that is your choice, you will notice In my original response I made no mention of it. It would however be wrong to promote such methods and practices as normal to DR techs at the start of their journey when they enquire about it.

Hope you now understand other aspect of the case.

I have always understood - I just don't agree

[higgsboson]

Thanks for your understandings.

Like you said technology to be used on many parameters.
Supposedly if you are from developed countries like USA /Europe etc where client paying capacity is more than developing countries .
It depends upon type of customers as well.
If same case comes up from a corporate customer having mission critical data then imaging might be suggestable as $$$$ is involved and customer is willing to pay.
Now if same case comes from a home or small customer who is not keen om imaging and only on price then its wise not to do imaging.
In america if you might be able to convince customers how important (and professional too) is imaging and charge exorbitantly for the same.
But that might not be the case in changing business dynamics elsewhere.
I think real professionalisam does not always means to image disks unncessarily but to offer most affordable solution to customers.

I hope you know there are many professional softwares having linux based live media exclusively designed for logical Raid recoveries supporting basic /mid level raid configurations. In case Raid configuration and disks are 100% safe its wise not to remove them and add complexity.

Yes this workstation has SATA dvd writer which is caddy type .Its power supply is different and not standard .
