We performed a comparison between Cohesity SpanFS and Oracle ZFS based on real PeerSpot user reviews.
Find out what your peers are saying about Nasuni, WekaIO, Oracle and others in File System Software."It has snapshot capabilities. We take advantage of those."
"Scalability-wise, I rate the solution a ten out of ten."
"The replication capability and data security have been the most valuable features."
"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."
"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."
"Its read performance can be improved. It is just slow in comparison to other file systems, but a lot of it also has to do with the fact that they have a limited number of spindles under each node."
"The only problem is the current performance of the individual nodes. As a sale-out solution with integrated load-balancing functions, performance is in principle not a problem at all. Capacity and performance are linearly scalable over the number of nodes in the cluster. An increase in the performance of the individual nodes in future releases would be desirable."
"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."
"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."
