Room For Improvement

IBM FlashSystem requires enhancements in scalability, integration, user interface, and support, with better deduplication, monitoring, and streamlined processes.
Panzura CloudFS needs improvements in performance, compatibility, pricing, dashboard, alerting, licensing, Active Directory reliance, NFS service, and support.
Despite marketing promises, these features do not function effectively and can impact performance.
Vice President Sales at BELOCAL LTD
There is room for improvement in the troubleshooting part, specifically related to IBM Spectrum for Insight.
Manager, Technical Services, IBM Storage & Backup Solutions. at Thakral
An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated.
Storage Specialist at a computer software company with 1,001-5,000 employees
When something goes wrong somewhere, there should be a little bit better alerting with issues before they become a big problem.
CIO at Mead and Hunt, Inc.
The GIS data formats, such as a geo database, have been found better kept outside of Panzura CloudFS.
Senior Vice President, Technology at Halff Associates, Inc.
It would have been nice if they had offered them in increments, of 5, 10, 15, or 20 terabytes than having to get a whole chunk of 25 terabytes again for licensing purposes, which is a little costly.
I.T. Infrastructure Manager at Thompson Engineering
 

Setup Cost

IBM FlashSystem offers competitive pricing, but evaluating long-term needs and negotiating discounts is crucial to manage costs effectively.
Panzura CloudFS pricing is higher than competitors, lacks granular licenses, but offers negotiation flexibility and transparency.
To install or upgrade any software features, the cost is high, which makes it challenging for smaller companies who do not require advanced features like deduplication or compression typically needed by larger organizations.
Vice President Sales at BELOCAL LTD
The pricing is high; storage solutions are always expensive.
Freelancer at a logistics company with 10,001+ employees
It did require us to purchase new hardware, however, that was not overly expensive.
Senior Vice President, Technology at Halff Associates, Inc.
They should consider more attractive pricing for companies of our size.
I.T. Infrastructure Manager at Thompson Engineering
Overall, it is quite costly compared to NetApp and similar solutions.
Technical Expert at a manufacturing company with 10,001+ employees
 

Valuable Features

IBM FlashSystem delivers high performance, user-friendly management, and scalable efficiency with robust features like deduplication and virtualization.
Panzura CloudFS enhances workflows with high availability, security, and seamless collaboration, reducing storage costs and boosting productivity.
There is a significant amount of data reduction, achieving a ratio of one to three.
Storage Specialist at a computer software company with 1,001-5,000 employees
The most valuable features are performance and reliability.
Freelancer at a logistics company with 10,001+ employees
There is built-in compression, a data reduction feature, and artificial intelligence-driven insights that calculate warnings and errors to redirect to customers automatically.
Manager, Technical Services, IBM Storage & Backup Solutions. at Thakral
It is very reliable and very quick.
CIO at Mead and Hunt, Inc.
It helps us increase network resilience. We have a primary object library stored in the cloud and have Panzura Mirroring which allows us to place data in a secondary cloud for added resiliency.
Senior Vice President, Technology at Halff Associates, Inc.
There is no degradation of speed because these filers have cached the data, and they are constantly swapping metadata and updating with each other, which is a very attractive method of getting us to use these applications.

Featured Reviews

OmarIsmail1 - PeerSpot reviewer
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.
Roger Clark - PeerSpot reviewer
I.T. Infrastructure Manager at Thompson Engineering
Handles file locks effectively enabling seamless remote collaboration in global teams
It has not reduced the data storage cost. We have been trying to come up with a plan internally to archive project data at a certain time frame. However, our data continues to grow, so at the point of 25 terabytes, we had to buy another 25 terabytes license to exceed that threshold. It would have been nice if they had offered them in increments, of 5, 10, 15, or 20 terabytes than having to get a whole chunk of 25 terabytes again for licensing purposes, which is a little costly. It would be nice if Panzura offered data in increments instead of 25 terabytes per license. They have done a pretty good job of development from the point of offering new products. Pricing seems to be high for certain things, such as the audit feature of Panzura Data Services. It would be nice to see who deleted that 100 gig of data out there. They should make the pricing plan more attractive for a company of our size. We have almost 700 employees over the southeast from Texas to Florida and up to Tennessee, so we are a pretty big region.
