Re: [PLUG] Is it possible to move data from a SAS drive to the newly installed SSD?

Not sure how much has changed, but a 2018 article by Jameson Lopp said, and I quote:

"Running an archival Ethereum node requires a ton of disk I/O since you’re executing every smart contract ever performed in the history of Ethereum and updating the state on disk. It’s common knowledge now that if you try to sync an archival node on a machine with spinning disk drives, it will never catch up to the tip of the blockchain — there simply aren’t enough IOPs available. Thus, you MUST have a solid state disk to run an Ethereum node."

Yes, it's possible, if you can have both PERCs installed at the same time. If they're PCIe models, you're fine, if they're the proprietary Dell semi-integrated modules, you'd need to remove the one to install the other.

Hi,

I have my Dell R510 server configured with raid 6. It has been downloading Eth1 (Geth) chain for last 4 days and it’s not even half way done.

I am finding out now that even if the chain is fully downloaded and synced, I will have issues with the SAS drives because they’re too slow for this purpose.

I am thinking about upgrading the perc card to the 8700 and upgrading a few drives.

Would it be possible for me to move the already downloaded data to the new drives or would I have to download everything all over again?

Thanks
