IBM PowerHA SystemMirror vs. NetApp MetroCluster

In every organization, we have some of the critical applications in on Premise datacentre were a lot of dependencies in a picture in terms of application as well as a business where we can make highly available to this application by using Power HA Systemmirror by using this we can avoid last time surprises.

NetApp MetroCluster is suited for applications which require 100% uptime with no data loss. It is suitable for organizations who have the need to move their NAS services and workloads to another data center with minimal downtime and configuration. Due to the cost of the product, it is not well suited for NAS file shares that require greater than zero RPO and RTO's. NetApp asynchronous is better suited for this type of data.

• High performance during peak business hours
• No downtime during critical business operations
• Easy updates

Incentivized

• Data deduplication, compression, and compaction provide great savings compared to traditional host based storage
• Multiprotocol support (NAS and SAN) provide great flexibility
• Ability to easily run your workloads from either data center with minimal effort and no disruption was the key selling point

• IBM Sybase replication has been an issue for those who don't [use] MIMIX on their systems to keep the Sybase up to date.
• The graphical interface really needs an update.
• Technical support isn't as responsive as it should be.

• I would like to see more highly intelligent monitoring that can help determine where latency is coming from. Eg. Host, Array, Network or Fabric issues

As I am having long experience with this so no doubt, I am very confident for it where I can deploy easily and manage easily in terms of any issues can go with multiple logs and take further actions on it to fix the issue in a swift manner which matters a lot to me. That's why I have given higher priority to it.

Have not used or evaluated any other NAS synchronous products.

Incentivized

• There will is no single point of failure in PowerHA SystemMirror
• High performance in PowerHA SystemMirror
• TL upgrades are easy without any impact

Incentivized

• By moving critical application data away from older based technology such as host based mirroring and to a centralized array based replication, the complexity of managing data from multiple source and destination servers has been removed.
• The number of incidents compared to our previous legacy configuration is huge. Data uptime has been 100% available since the migration to NetApp MetroCluster.
