The replication capability and data security have been the most valuable features When retrieving data from the replication of remote sites, it does not give you immediate results. The RPO and RTO rates could be improved. We have been using this solution for three and a half years. This is a…

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.

The question is, can it do a lot better? So for example, it could run an airline, and all the computer systems, but can it do it as effectively and efficiently as it could on other systems? No. That's where you start hitting things like you could store library congress on it 50 times, but does that mean that it's usable? If you want to find a book, do you want to wait a minute to get your results back or would you rather get your results back in two seconds? ZFS can always get the job done and it's reliable but it's just not always fast enough, and that's the main problem with it. 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. For companies or organizations using Kubernetes, multiple Docker instances, or the spin-up machines needed to handle the workload need quick media just for the host itself to be able to run things quickly, but ZFS does not do that. What's important these days is, as you run stuff as a cluster, you want to be able to replicate from one cluster to another, whether that's done in the background or is done in near real-time. ZFS just does not do anything of that nature. You have to use a third-party product or Ceph storage, which we use also. So that's why it's limiting from that standpoint.

Valuable Features

Oracle ZFS features a unique pooled storage model allowing thousands of file systems to share space efficiently. Built-in compression, deduplication, and self-redundancy eliminate the need for RAID controllers. It offers fast, reliable data management, outstanding replication and security, intuitive usability, and effective Snapshot and Rollback capabilities. The system excels in demanding workloads, enabling high performance even on aging or less powerful hardware when configured optimally. Data integrity is assured with checksums and automatic repairing of damaged copies.

"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."
"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."

Room for Improvement

Users indicate Oracle ZFS encounters performance issues, especially with NFS mounts and Proxmox, where RAM usage is high. Drive scrubbing frequency and difficulties with resizing arrays are noted. Users mention data retrieval from remote replication lacks immediacy, and RPO/RTO rates need enhancement. ZFS struggles with fast storage and real-time replication in clustered environments. It's effective for mass storage but not agile enough for rapid operations. Cost concerns are also highlighted, suggesting a need for price reductions.

"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."
