Dell PowerScale vs. HPE MSA

EMC Isilon Scale-Out NAS is well suited for larger files (greater the 128 Kb) and where you need to have everything in one common name space. Where it is less appropriate is for many small files (millions of files less than 128 Kb in size) - this causes the protection level to becoming mirroring, which will cost more space.

The HPE MSA is best suited for basic SAN requirements. Having dual controllers provides redundancy and allows for firmware upgrades without incurring downtime to the environment. It provides enough IOPS for most workloads be it VMWare or servers requiring storage. For applications such as MS SQL or Exchange, other SAN solutions would be better. Plus the lack of storage snapshot capabilities is also a detriment to the product line. Lack of any reporting capability is also an issue especially when determining workload capabilities.

• Functions well as a disaster recovery cluster repository
• Since the space is a spinning disk, it is inexpensive
• All of our VMs are stored in a mass storage repository on the system, but we could carve out specific LUNs if needed.

• Some upgrades require the entire cluster to be rebooted simultaneously. In this day and age, that should not be necessary. This is my biggest disappointment with Isilon to date.
• When using multiple storage pools you have to be very careful with your capacity management. Filling up one pool can cause an overflow of data to a pool that is less performance driven. Do not underestimate your capacities or you will find yourself in a tight spot.
• Block size is almost always an issue with Isilon. It does not handle all types of data well. In many cases PACS and VNA data is best to be stored on a different storage platform that will utilize the capacity more efficiently that Isilon is capable of.
• Deduplication seems to be less efficient on Isilon than on other platforms for similar types of data.

• Firmware upgrades. We have had major issues on two occasions, causing extended downtime. HP was quick to help and resolve, but I am not sure why our simple implementation caused an issue that should have been picked up by testing prior to release. Once was bad, twice painful. The end result is that we purchased a unit solely to test firmware upgrades on, not really great for us!
• Support life span. Units go end of life support after around 4 years, a little too short for us.

It is a functioning Replication system for us and checks all the boxes that the auditors are looking for. Further, it is inexpensive and the storage we purchased was cheap. HP has a good reputation in the industry that plays into the decision also.

Raw disk space vs. logical disk space ratio was significantly better on the Isilon. Fast cache using SSD drives for faster searching is available on the Isilon but not available on the Overland solution. Isilon solution included faster backend switching between nodes.

The dual controller configuration of the HPE MSA trumps the Synology DiskStation's single controller configuration. For that alone, I would select the HPE MSA. Without that setup, any controller issue or firmware upgrade is disruptive to the systems the SAN is providing storage to. Furthermore, HPE's support is better than what Synology currently provides. The lack of phone support on Synology's part slows down the troubleshooting of issues compared to HPE. Furthermore, HPE's engineers are able to do a remote session and can work on the problems directly compared to Synology's support.

• Isilon provides very high value for money
• Matches the performance and storage requirements of the arrays
• EMC provides very skillful and high response team in case of any issues in isilon

Incentivized

• Increased up time. Better user experience.
• Good value for money. ROI high.
• Peace of mind. Just knowing that you rely on the solution to meet storage performance needs is great.
