DDN EXA5 vs Oracle ZFS comparison

"The DDN Exascaler uses a parallel file system, Lustre, which is proven for HPC and AI workloads."

"The performance is outstanding, and customers are very happy with it."

"Oracle ZFS is very fast and it is efficient. It has outperformed any hardware array controller that I've ever come across. With Oracle ZFS on my NAS, which is running five, four terabyte drives, when I've had a drive failure and changed one out, it'll rebuild that array in two hours, or maybe less. When you think you're rebuilding almost four terabytes of data redundancy, that's pretty good using an old AMD Turion hardware, that's nothing to complain about."

"The replication capability and data security have been the most valuable features."

"It is not necessarily for the fastest storage or cluster storage, but just for pure storage, it's really hard to beat. It's just been around as long as anything else."

"There are challenges with the operation cost and upgrading process, which is disruptive, especially with the node."

"ZFS is great for just mass storage, but if you're trying to make fast storage – something like a SAN-type delivery network where you wanted to do any type of RAM disc over the network – it falls flat. ZFS does not do that. It is kind of limiting."

"When retrieving data from the replication of remote sites, it does not give you immediate results. The RPO and RTO rates could be improved."

"Oracle ZFS does what I've asked it to do, and it has done it very efficiently. The only time I'm running into issues is with Proxmox. If I run ZFS drives, I find my RAM usage is very high. However, I don't have that problem with the TrueNAS system, where I'm running an old N36 Turion with four gigabytes of RAM, and that's running 24/7. There have been no issues with such a low-powered environment there, it works fine, but with Proxmox it seems to go slow."
