HPE MSA 2042
HPE is already the industry’s leading entry SAN array in both market share and performance, the new HPE MSA 2042 comes with a built-in flash acceleration and enterprise data services right out of the box.
The natural affinity of the HPE MSA storage and HPE ProLiant Servers have helped HPE to consistently remain at the front of the entry storage pack.
HPE MSA 2042 is the newest member of the family, it takes the HPE MSA 2040 and builds in two 400GB SSDs, also includes the new Advanced Data Services Suite with the following capabilities:
- Provides support for 512 snapshots
- It has remote snapshot replication
- Performance Tiering capability
The last feature on the list is really interesting. Performance Tiering is now included at no extras charge; this means that you can use the system’s built-in flash capacity not only for Read Caching but also for general application acceleration – without having to spend another penny. Including the two SSDs plus all of these other software features, MSA customers are saving an extraordinary 54% with this new model.
Advanced Data services is another thing to keep in mind, as this is in addition to all the other advanced storage virtualisation features which are offered by the MSA this includes SSD Read Caching, thin provisioning, wide striping, large pool support and redirect-on-write snapshots.
Read cache vs. Performance Tiering
To get some hard data, HPE had Demartek lab test the MSA 2042 against the same configuration although without the built-in flash and here are the results of the testing:
- Performance Tiering Results for MSA 2042:Database transactions per second: +60%
- Latency: 11x improvement
- Throughput: 4.6x improvement
- IOPS: 4.5x improvement
- Read Caching Results for MSA 2042:
- Database transactions per second: +35%
- Latency: 4.5x improvement
- Throughput: 2.5x improvement
- IOPS: 3x improvement
You need to keep in mind that these numbers for Read Caching and Performance Tiering are comparing the MSA 2042 against the same system although without the 800GB of flash which now comes standard.
Since using the SSD capacity for the read caching which mainly accelerates application reads, most customers will probably find that enabling the performance Tiering on the new MSA 2042 array returns the best performance results, although of course there might be some very read-intensive work loads which is when read caching is the way to go.
Most important thing to remember is that with both options and the flash now standard you have a choice for accelerating your apps which are based on the workload patterns without being limited by the software which you have installed.
To conclude, it is important to remember that in addition to the new MSA 2042, the new inclusive software pricing also gives the existing HPE MSA 2040 customers the option to add SSD capacity and the Advance Data Services Software Suite to an existing system. This means you can achieve the same performance levels on the MSA 2042 for 40% less than what it would have cost previously. Remember not only do you get two choices for accelerating application workloads, also the existing MSA customers can benefit from what the little flash can do!
