We performed a comparison between Dell SC Series, Huawei OceanStor V3 Storage System, and VMAX [EOL] based on real PeerSpot user reviews.
Find out what your peers are saying about Hitachi Vantara, IBM, Dell Technologies and others in Frame-Based Disk Arrays."The user interface is good, I would rate it a nine out of ten."
"A valuable feature is the performance of the auto-tiering. It will move hot data up to your fastest Tier 1 or move your slow data down. Data progression is what it's called. With the auto-tiering you can have multiple tiers, you can have your Tier 1 be either spinning or flash, all the way down to 7.2K. It will change the RAID on the fly so your writes come in at RAID 10. After they sit for a while, they get converted to RAID 5, then they'll cool off and move down the tiers. Your performance is kept going, while the cold data is moved to your slow, non-performance tiers."
"With auto-tiering, it's easier to understand than most arrays, knowing that all of your writes go to the tier that you specify, with easy-to-create storage profiles."
"Connecting it up, you can run it within a few hours."
"They have a feature called Live Migrate; it's been very, very useful."
"We replicate between SAN to SAN for a lot of features and supportability. It also helps us when we want to upgrade to a newer SC Series or move the data from one data center to another."
"What is most valuable about the Dell EMC SC Series system was its reliability."
"It's very scalable, especially with federation. If you outgrow the number of spindles that a unit can support, depending on the model, you can go into federation."
"Huawei has a lot of penetration into accounts in Islamabad and the whole region, especially in Islamabad, because this is where our capital is, this is where most of the government offices are."
"The interface is good, and it is also customizable."
"I like the many new features, especially the all-flash solution."
"We have never had a bad experience with it because we never had failures. It has good data availability and the performance is also okay."
"A rock solid foundation to deploy applications which cannot incur a disruption of service."
"We have been able to present storage from the VMAX to hosts without any problems."
"Deploying, Expanding, and Modifying systems are easier than ever."
"This solution is resilient."
"The most valuable features are the interface and performance."
"We had times that we needed a file service solution. We've used FluidFS, but it's a solution that is being transitioned out."
"The lack of reporting would be the main issue."
"An issue we had was that the controller went down during an upgrade because of their upgrading the code. One side of the switch was down."
"The configuration could be easier in Dell EMC SC Series."
"The initial setup is somewhat complex and should be made simpler to do."
"In terms of additional features, I would like to see some kind of I/O meter, to indicate what we are using in terms of performance. I would like to see automation with that, where it would give me the trends. I want to know those things easily, to help me know where issues are going to occur."
"While the scalability is good, there are certain limitations."
"The SC Series doesn't support NVMe storage."
"It is an expensive product. They should lower the price."
"The cluster support should be improved."
"I would like to see support for high-availability."
"I'd like to see improvements where we can scale out an existing array and remove older controllers\drives\etc., within the same subsystem."
"The way you configure larger size volumes needs improvement."
"Better speed to release new features that have become industry standards. EMC created so many standards in the past. Now, it seems they are playing a me-too game and lagging behind in some areas, specifically data reduction."
"The pricing is a bit expensive. That is the reason we are now currently we are looking for other solutions. That's the reason we are looking at AFF and Unity. We are also considering PowerStore."
"Resilience replication, reporting, and performance need to be improved."
"I would like this solution to integrate the solution that EMC vPlex offers."
