Along with offering competitive prices, the solution can be used by small, medium, and large businesses

While guaranteeing the strictness of the file system, there is a lot of performance involved. The performance is not as good as I expected. It's not the functionality here but the performance level. It won't be a problem if it's twice as fast. Even though its stability has room for improvement, I would recommend it to my bigger customers. 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.

Efficient setup and seamless performance ensure an outstanding experience

Everything in Oracle ZFS is great and it's easy to use, making it very user-friendly. I have used Oracle ZFS Snapshot and Rollback capabilities, and everything has worked well. The Snapshot and Rollback features in Oracle ZFS are awesome - that's one word to describe it. It's cool, very easy, and stress-free. Without doing benchmarks with other products, I can rate data compression in Oracle ZFS about an eight or nine out of ten, and I have noticed some deduplication and indexing features. Regarding how Oracle ZFS handles demanding workloads, such as online transaction processing and complex query executions, most of these aspects depend on your configuration setup. For instance, if you are using virtualization and have enterprise solutions on these servers, you can route or place database servers on SSDs or flash disks to enable better throughput from these systems. You can run your operating system on flash disks, or alternatively save ordinary data on SATA disks, depending on where you place your valuable data. The structure will affect performance, so if you plan it properly, you can achieve the best performance, even if the systems are aging or if you don't have the compute power, you can still balance it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We switched over to it because it is an integrated solution that includes DataProtect and the platform, has other use cases for enterprise search, and can also do things like antivirus."

"It has snapshot capabilities. We take advantage of those."

"Scalability-wise, I rate the solution a ten out of ten."

"Oracle is one of the most stable storage solutions that I have comes across."

"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."

"Oracle ZFS is highly stable; the solution is phenomenal in terms of picking up the warnings on pending drive failure through smart monitoring, and when you pull the drive out and rebuild the array with the new drives, it's been incredibly fast and I have not lost data."

"Everything in Oracle ZFS is great and it's easy to use, making it very user-friendly."

"Simply amazing filesystem."

"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."

"It is a pooled storage model and volumes are no longer needed, so thousands of file systems can draw from a common storage pool, each one consuming only as much space as it actually needs."

Cons

"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."

"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."

"Drive scrubbing needs to be run every week for consumer drives, and every month for enterprise drives."

"When retrieving data from the replication of remote sites, it does not give you immediate results."

"While we did not experience any performance issues with ZFS, it seems it is quite possible to run into performance issues especially with NFS mounts."

"If I run ZFS drives, I find my RAM usage is very high."

"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."

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

"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."

Pricing and Cost Advice

"When it comes to pricing, I know the prices because I am also running tenders for customers where I am not offering other solutions. Hence, the prices are pretty competitive."

"I won't talk about specific numbers, but it is a little hard to compare it to other products out there because there is nobody out there that does exactly what they do. If you are just comparing it to another NAS box, it is probably going to look higher, but that's an unfair comparison because it does things that a NAS box can't do."
