Operational tasks such as provisioning storage and monitoring performance happen faster, and less downtime risk and hardware consolidation mean we support more workloads with fewer resources and less data center overhead.
We have never had an outage in my four and a half years, but in our company's ten or eleven years, there has never been any planned upgrades that required downtime.
In the long term, spanning three to five years, the total cost of ownership becomes cheaper, considering power consumption, data center footprint, and NVMe technology usage.
For anyone new to the company, it is very easy to understand what is going on, how to manage, how to get access and know what it is doing.
We try to achieve a return of interest within around 18 months for a three-year contract and 36 months for a five-year contract, just as examples to get the money back.
The data points of my return on investment include the protection for mission-critical operations and IT infrastructure, better performance, and the assurance of a good investment.
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.
Pure's support organization is responsive with minimal bureaucracy, making support a key factor in customer retention.
I would rate the technical support an 11 out of 10.
Everpure FlashArray is probably not cheap storage, but it provides great performance, scalability, and everything a customer needs.
About 99.9% of my problems were resolved when I contacted them for technical or non-technical issues.
I simply tell them, 'This system is doing this,' and they already know what to do next.
HPE has maintained the people who built the platform, keeping Nimble's engineering team mostly intact to ensure they know how to drive and support it.
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.
A big banking client had around 300 petabytes of data on Pure Storage.
Our customers can scale up or scale out, raise the performance, and expand the storage spaces by investing every year.
We have successfully upgraded the controllers, scaled capacity, and scaled arrays without much impact on the system and with seamless planning.
Alletra provides modular, non-disruptive scale-up and scale-out.
If we do grow beyond what the appliance already has, we know that service will take care of it and grow the appliance for us without needing to forklift upgrade.
Evidence for this is the ability to add components and upgrade storage while the storage array is still running.
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.
For stability, I rate it a ten out of ten.
We have continuous 99.9% uptime and do not experience any users reporting performance issues due to latency.
The vision Pure Storage FlashArray offers through the GUI is clearer; we can discern the status, what is cabled, and how direct flash is enabled.
I have not experienced any downtime, crashes, or performance issues.
I have experienced no issues yet, so I assess the stability and reliability of HPE Alletra Storage as 100%.
I have not experienced any downtime, crashes, or performance issues on these arrays.
Customers have infrastructure that is 100% stable.
The firmware and software engine have fewer bugs, which enhances operational efficiency.
Integrating object storage into the FlashArray would benefit entry-level and SMB customers by offering a more unified solution.
Storing cold data on expensive arrays doesn't make financial sense, and tiering to any of the big three cloud providers would be advantageous.
As a technical professional, I lack visibility into the system logs.
Everything is performing well with no major problems or complaints and complete data protection.
The conversations should focus on how AI can augment what people are already doing, allowing them to move to higher-value tasks rather than replacing their positions entirely.
The HPE Storage Technical Assistance Center is still probably the best out of all the storage vendors.
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.
They're expensive.
While they say it's free, we actually pay for support upfront.
Some smaller organizations may find it slightly expensive, but for enterprises, when considering performance, future hardware investments, and overall benefits, it is a very cost-effective solution for mid and enterprise organizations.
The setup costs were in some cases half the price of some of the other competitors with even more features.
For the one SAN I'm paying monthly as GreenLake hardware-as-a-service, the total cost of that subscription has a value that far outpaces what it would have taken to buy the same capacity outright.
I don't believe HPE Alletra has helped reduce the cost per terabyte, as it is competitive with other products, maintaining a similar price point.
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.
The pricing is high; storage solutions are always expensive.
FlashArray's integration with the Pure One instrument provides a centralized platform for efficient management of all arrays.
Another noteworthy aspect is their platform, Pure One, a cloud-based analytics platform that automatically creates a case and sends out a part if a disk or controller fails.
It handles internal data migration seamlessly in the background without going offline, achieving a hundred percent uptime.
Alletra helped reduce the time in storage provisioning. We have reduced it by two hours. Before switching solutions, it used to take us two to three hours, and we have reduced it to about 15 minutes with Alletra.
The technology uses NVME for increased storage, latency, high bandwidth, and sub-millisecond response times.
This solution simplifies storage operations and provides predictable performance and capacity for applications.
There is a significant amount of data reduction, achieving a ratio of one to three.
The most valuable features are performance and reliability.
