Differences Between Oracle ZFS5-2 and Oracle FS1-2

This question may be moot now. Oracle EOL'd FS1 and RIF'd most of the FS1 staff a while ago. While both ZFS (now ZFS7) and FS1 are/were unified storage systems, ZFS is primarily NAS; FS1 was primarily SAN with some QoS and multi-tenancy features and such.

Has a fantastic feature-set and works well with workflow solutions

I would suggest, if you heavily depend on the Oracle solution from the database you should consider Oracle All-Flash because, from my understanding, it is from a single OEM, it's a single solution. It would be a homogeneous environment. I think it would be definitely a better option for customers considering other all-flash storages. It would be better if you consider a solution from Oracle, from the database studio, the storage part. I would rate it an eight out of ten. To make it a perfect ten, in the next release, I would like for it to be NVMe compliant storage.

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

"It's actually shaking hands with the workflow solutions much better than any other storage."

"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."

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

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

Cons

"It has to be flexible according to the customer's requirements. It has to be aligned with the customer business and the business environment."

"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."

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