Review summaries and opinions

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

ROI

Sentiment score
6.7
IBM FlashSystem offers easy migration, improved performance, seamless integration, cost efficiency, and quick ROI, enhancing user satisfaction.
Sentiment score
5.1
Organizations experienced enhanced resilience, doubled performance, and productivity gains by adopting Panzura CloudFS, solving past file storage issues.
The solution can comfortably be stretched from five to seven years without any failures, ensuring a long-lasting return.
We have seen return on investment compared to other OEMs, which took approximately three years after implementing IBM FlashSystem.
Previously, we had latency issues with syncing up files between offices. Files were not locked, leading to overwrites which cost us literally hundreds of thousands of dollars in lost time and revenue.
We saw the benefits of Panzura CloudFS immediately because our remote offices were able to share files immediately after the product went live.
Panzura CloudFS saves us a significant amount of time frequently.
 

Customer Service

Sentiment score
7.0
IBM FlashSystem support reviews are mixed, with praise for response speed but criticism for regional expertise and complex escalations.
Sentiment score
6.8
Panzura CloudFS support is praised for quick, expert assistance despite occasional delays, receiving high ratings from users.
Customers of alternatives like Dell and Hitachi enjoy more reliable and comprehensive support services directly from vendors rather than third-party subsidiaries.
I rate the technical support from IBM as a ten.
IBM customer support is responsible, efficient, and responsive, though it is expensive.
The support staff and the number of people they have on staff right now are truly good.
When we have a priority-one issue, we typically receive a call within 20 to 30 minutes.
I would give the support for Panzura CloudFS a ten out of ten because they are responsive and helpful.
 

Scalability Issues

Sentiment score
7.3
IBM FlashSystem is praised for its scalable, flexible expansion, suiting diverse enterprises and integrating well with current systems.
Sentiment score
6.8
Panzura CloudFS is highly scalable, effortlessly supports many users across locations, with seamless deployment and dedicated support.
For larger enterprises, scalability is an issue as the price becomes prohibitive.
The problem arises when migrating data to a later IBM FlashSystem version due to issues with firmware compatibility.
The scalability of IBM FlashSystem is exceptional, and I rate it as a nine.
Unlimited users can access the system without issues.
From our original entry with Panzura CloudFS, we have added an additional seven sites, and deploying those additional nodes was very seamless and did not take any effort.
The latest version, 8.0.2, has better ease of decommissioning filers and bringing new ones online.
 

Stability Issues

Sentiment score
7.6
IBM FlashSystem is generally stable and reliable; however, some users experience issues due to specific configurations or hardware conditions.
Sentiment score
6.1
Panzura CloudFS is highly stable with rare outages and improved reliability, earning high user ratings overall.
Customers have infrastructure that is 100% stable.
The firmware and software engine have fewer bugs, which enhances operational efficiency.
I would rate it a nine out of ten for stability.
We have never had their system crash on us.
There were times with file lock issues between filers, causing various anomalies, but with their ongoing development, these issues have improved.
 

Room For Improvement

IBM FlashSystem needs improvements in capacity, GUI, support, data reduction, cloud integration, and stability for better competitiveness.
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.
There is room for improvement in the troubleshooting part, specifically related to IBM Spectrum for Insight.
An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated.
When something goes wrong somewhere, there should be a little bit better alerting with issues before they become a big problem.
The GIS data formats, such as a geo database, have been found better kept outside of Panzura CloudFS.
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.
 

Setup Cost

IBM FlashSystem pricing is competitive but can be higher; users stress evaluating total costs, including software and support.
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.
It did require us to purchase new hardware, however, that was not overly expensive.
They should consider more attractive pricing for companies of our size.
Overall, it is quite costly compared to NetApp and similar solutions.
 

Valuable Features

IBM FlashSystem, known for high performance and reliability, excels in storage virtualization and advanced features, enhancing data efficiency.
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.
There is built-in compression, a data reduction feature, and artificial intelligence-driven insights that calculate warnings and errors to redirect to customers automatically.
When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand.
It is very reliable and very quick.
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.
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.

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
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.
