IBM FlashSystem and Huawei OceanStor compete in high-performance storage solutions. IBM FlashSystem has an edge in performance with high IOPS and low latency, while Huawei OceanStor provides strong integration capabilities and competitive pricing.
Features: IBM FlashSystem delivers high IOPS performance, low latency, and ease of management with features like compression and virtualization. Huawei OceanStor offers NAS and SAN integration, high availability, and reliable IOPS.
Room for Improvement: IBM FlashSystem's high costs and NVME host attachment limitations are areas for improvement, alongside deduplication technology. Huawei OceanStor faces challenges with regional support, configuration complexity, and interface improvements.
Ease of Deployment and Customer Service: Both IBM FlashSystem and Huawei OceanStor support versatile deployment options including On-premises, Hybrid, and Private Cloud environments. IBM FlashSystem is straightforward to set up, while Huawei OceanStor offers an easy management interface, despite regional support disparities.
Pricing and ROI: IBM FlashSystem is competitively priced for long-term users but perceived as high-cost. Huawei OceanStor provides attractive market pricing and cost-effectiveness, despite concerns about licensing model complexity.
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.
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.
Huawei took longer to respond and send a new device when something critical happened.
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.
Huawei OceanStor is capable of scaling up to a few megabytes and is equipped to handle varied network protocols.
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.
Huawei OceanStor is stable and reliable for storage solutions.
Other than the data store running out of space, I haven't had any issues with the technology.
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.
Huawei currently lacks a solution for high-performance AI, unlike other companies like DDN, WekaIO, or IBM BlueStore.
The stated capacity was not a true reflection of the actual capacity.
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.
Huawei is priced competitively, encouraging companies to consider it over other products.
Huawei OceanStor's pricing is very aggressive, making it highly competitive.
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.
Huawei OceanStor offers good IOPS and is reliable and energy-efficient.
The main selling point of Huawei OceanStor is its ability to handle all storage protocols, including block, file, and object.
There is a significant amount of data reduction, achieving a ratio of one to three.
The most valuable features are performance and reliability.
There is built-in compression, a data reduction feature, and artificial intelligence-driven insights that calculate warnings and errors to redirect to customers automatically.
