Dell PowerScale vs. Striim

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.

Below samples are the well suited use cases; - Change data capture feature seamlessly works on popular RDMS. You can make enrichments on several data sources within the same Striim application. - You can install stand alone agents and start streaming log files to Striim servers. This is mainly useful for security operations or audit trail use cases.

• GoldenGate Trail reader which iss faster than Oracle CDC. It does not used logminer, hence there is no load on source Oracle database.
• Easy installation and upgrade in 5 minutes
• Support is very good. Fast and user friendly.

• 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.

• License a bit expensive

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.

Faster, checkpointing better. CDC works well. The loading is faster. Easy upgrade and installation. Uses less resource.

• 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
