Infrastructure Technical Specialist II at Clicks Group
Offers high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.

Has supported continuous broadcasting with reliable performance and consistent operations
They can make more solutions for cloud integration in NetApp Private Storage. It should be easier to use the cloud S3 integration, maybe from a NetApp interface, where users can choose the type of storage before sending to S3. I would like to see more audit and performance logs via cloud integrations and ONTAP. Without the need for separate software.

Quotes from Members

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

Pros

"For space saving features, it definitely saves us in a virtual environment in terms of space and money."
"If someone wants a robust, scalable, and consistent behavior for their site, then they should use IBM FlashSystem."
"IBM Storwize makes management of the IT environment much easier, with high availability and enhanced security, proven dependability, data compression with hardware acceleration, and advanced copy services features all in this product."
"The valuable features are high availability, compression, and a failover mechanism. It's a very highly available storage solution."
"User friendly management interface."
"The ease-of-use and scalability are the most valuable features."
"IBM FlashSystem is a flexible solution with plenty of features."
"It's a mature product. It's like a BMW that evolves consistently."
"The most valuable feature is integration."
"Integration with other NetApp solutions and merging them is manageable."
"Its flexibility and ability to configure volumes is its most valuable aspect; I have no problem configuring the product for different kinds of use cases and configuring throughput or configuring some kind of logical volumes and so on."
"If your company has the budget for NetApp Private Storage I would recommend it."
"At the moment, we are extensively using SnapMirror."
"We get our data faster and it's very reliable; we don't go down."
"The solution is stable."
"Very stable and very scalable."
 

Cons

"We had issues when attempting to do a flash, we hope to resolve it soon."
"The Data Reduction Pools (DRP) support could be better."
"They can include Amazon file system S3 protocol in the upcoming releases. It is a cloud file system. IBM FlashSystem doesn't have this feature in the box for high-end or mid-range. We have got requests for this from customers because we need to use S3 for EDI application storage. At the beginning of every year, IBM releases firmware. When I find any bugs in the firmware during the year, I am unable to find any information from IBM regarding the bug. I need to open a ticket, and the IBM engineering team makes a patch only for me. This patch is not public. By creating a customized patch for a client, they don't really solve the issue for everyone. If multiple users have the same bug, IBM should upload the patch on the official website so that we can download it. IBM FlashSystem has a monitoring tool in the box, but it is not advanced. I need a more advanced tool for more advanced equations and monitoring. All top three storage vendors, that is, EMC, IBM, and Pure Storage, don't have a powerful monitoring tool. To monitor our box to show the statistics for I/Os and latency, I need to pay for extra software. The built-in monitoring storage is not mature enough to handle all requests and generate all reports that I need. They can include the functionality to stretch a cluster natively without using any additional boxes. In addition, there are some features that EMC has integrated with the box. These features are not available in IBM FlashSystem."
"The technical support in my region is satisfactory but it could improve. Support is very important for customers and downtime is very critical for us. We would like onsite or complete technical support which can help us to minimize our downtime or if problems occur."
"The cost of the solution is too high. They should work to make it lower."
"Technical Support: Not so good in my country because they only have a few people with great knowledge about FlashSystem."
"We have not had a good experience with this platform."
"My advice to anybody who is considering this system is not to do it. I do not recommend it; it is a big no."
"I'm not sure how easy it is to use on the cloud versus on-prem."
"The hardware does not last as long as it could with new software."
"The one thing I've noticed with NetApp when you buy hardware and you can use it for a while and then you have to get new hardware."
"I would like to see the GUI management simplified in the next release."
"The price could be lower."
"NetApp Private Storage is still integrated into the ISCSI connectivity and the FC protocol. I would recommend them to migrate to the FCIP because the SAN switches are moving further to an FCIP, and are scaling out of the ISCSI connectivity. Sooner or later, that will be an issue for NetApp Private Storage. An NFCIP should be available to them moving three years down the line."
"I'm not sure how easy it is to use on the cloud versus on-prem. If they have different user experiences, they should work to make the two as similar as possible to make it easy for a user to understand both even if they only deal mainly with one."
"The users find the new version's GUI complicated to use."
 

Pricing and Cost Advice

"Our customers would like IMB FlashSystem to be less expensive."
"The pricing is reasonable."
"This solution is expensive compared to other solutions."
"They've been much more aggressive in the last five, six years than they were before that."
"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."
"The total storage capacity vs price is still quite high for the IBM Flash Array."
"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."
"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."
"The price could be lower."
"It is an expensive solution."
"The price of NetApp Private Storage is similar to other solutions. There is typically an annual license required for this solution."
"In general, I am pleased with the pricing, though it is a little high."
"We negotiate whatever deal we can get on the type of storage that it is, but it's totally under our control,."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
"The product is costly."
