HP 3PAR StoreServ All-Flash crushes EMC XtremIO for SAP HANA TDI


Hasmig.jpegBy Hasmig Samurkashian, SAP Solutions Manager, HP Storage Marketing


One full year after the 3PAR StoreServ 7450c all-flash certification for SAP HANA Tailored Data Center Integration (TDI), EMC has announced its first XtremIO certified configurations. While this XtremIO result has a nice headline around 20 HANA node scaling. . . that's where EMC’s right to gloat begins and ends. HP 7450c all-flash solutions for SAP HANA beat XtremIO on capacity, drive counts, footprint, power, cooling, weight and price. And that’s only part of the story.  


How HP 3PAR StoreServ 7450c All-Flash compares to EMC XtremIO for SAP HANA TDI

Consider a comparison of the 3PAR StoreServ 7450c all-flash 4-node system that scales to 12 HANA nodes and the XtremIO 4 X-Brick configuration that scales to 14 HANA nodes. Here is what the 3PAR 7450c delivers:

  • Less than one-third the price. The 3PAR 7450c with 96 x 480GB cMLC SSDs has a list price of under US$600K. This is estimated at one-third the price of the EMC XtremIO 4 X-Brick solution with 100 x 400GB SSDs. Additionally, the 3PAR 7200c All-Flash solution has a US list price of under $200K, offering a low-cost entry point for SAP HANA TDI. The XtremIO entry configuration requires a 2 X-Brick array with 50 SSDs, at substantially higher cost than the 3PAR 7200c all-flash offering.
  • One-third the rack space. The EMC XtremIO 4 X-Brick configuration requires 23U in rack space. The 7450c uses just 8U of rack space, approximately one-third that of the XtremIO solution.


  • One-third the power consumption: The 3PAR 7450c 4 node all-flash array requires 1.2kW to operate, while the EMC XtremIO 4 X-Brick system requires 3.36kW. This means that the 3PAR 7450c all-flash consumes about one-third the power of the EMC XtremIO solution.
  • 60% less cooling energy: The 7450c 4 node all-flash array consumes 4,138 BTU/hour cooling energy, while the EMC XtremIO 10TB and 20TB 4 X-Brick system uses 10,612 BTU/hr. That is 60% less cooling energy required for the 7450c compared to XtremIO.
  • One-quarter of the weight: The EMC XtremIO 4 X-brick system weighs 343kg. The HP 3PAR StoreServ 7450c 4 node all-flash array weighs 90kg, one-quarter of the EMC solution.

Other noteworthy advantages of HP 3PAR StoreServ All-Flash over XtremIO for SAP HANA TDI

  • Scalability: 3PAR offers almost 4X the raw capacity scaling of an XtremIO 6 X-Brick. 3PAR can scale to 240 SSDs compared to only 150 SSDs for XtremIO. This allows 3PAR to scale to 460TB of raw capacity compared to a max of 120TB for XtremIO. 3PAR also supports cMLC drives providing an inherent cost advantage for customers. Additionally, XtremIO imposes scalability restrictions in that expansion must be first with a "brick" of 2 controllers and 25 SSDs then next with 2 bricks of 4 controllers and 50 SSDs.
  • Resiliency: 3PAR offers a highly available architecture that can handle shelf failures, double disk failures and data encryption. The 3PAR StoreServ 7450c is backed by the industry’s only 6-nines guarantee.
  • True scale-out architecture: Because additional controllers and disks can be added on demand. The EMC XtremIO array requires downtime to add additional bricks that is highly disruptive for SAP HANA environments. This has been a promised fix for XtremIO 4.0 although it is unclear when this capability will be available.
  • Ability to selectively use inline deduplication: This is critical to insure performance of SAP HANA workloads that are nearly non-deduplicatable. Inability to rely on deduplication creates an additional disadvantage for XtremIO. With support of large capacity cMLC SSDs, 3PAR’s dense form factor affords less space, less power and lower cost. Without being able to rely on deduplication, XtremIO customers will quickly be forced to grow to 4 or more bricks to get equivalent scaling.
  • Single architecture: 3PAR offers the power of a single architecture, including common management, software, and Tier-1 feature set for mid-range, high-end and all-flash. This is critical for complex SAP environments that require standardizing on a single primary storage platform for their entire environment.
  • Mature, proven data services: This includes Quality of Service (QoS) that enables guaranteeing performance SLAs. This capability is not supported by XtremIO yet it’s critical for multi-tenant SAP HANA environments where KPIs for HANA must be ensured.

Across the board, the 3PAR StoreServ 7450c beats EMC XtremIO for SAP HANA TDI. This includes certified configurations with fewer SSDs, higher capacity, smaller footprint, lower power and cooling and lower price Additional show-stopper weaknesses of XtremIO for SAP HANA include poor scaling, inability to turn off de-duplication and array resiliency. If you’re looking for an all-flash solution for your SAP HANA TDI deployment, 3PAR StoreServ all-flash storage is the superior choice.

About the Author


Our team of Hewlett Packard Enterprise storage experts helps you to dive deep into relevant infrastructure topics.


Regardless of HANA, every point above is relevant and drove our decision to go with a pair of 7440C as opposed to XtremIO (not to mention the lack of built in replication in the EMC solution).

Ability to selectively use inline deduplication, Really ? Sounds like ability to selectively wake up happy... I prefer to be happy inline.



Ben - not sure I understand your comment but there are some workloads (e.g. encrypted data) where deduplication doesn't help.So  we leave it up to the customer to decide if they want to use Thin Deduplication.


Most customers will not turn off deduplication and they don't need to worry about a performance impact because we dedup with the 3PAR ASIC. With any data that you are deduping, we NEVER turn off dedup and NEVER resort to post-processing as most others do that use inline deduplication.


So with HP 3PAR, its always "happy inline" unless you turn off deduplication for some of your data. 


Which competitor do you work for?


@chfemr - I've talked to more than a few customers who've made the same choice you did. It's a fun time to be in HP Storage with such a great portfolio.  Thanks for being a customer!

 A Few Questions :  


Why is HP comparing their cMLC drives vs eMLC drives  that are in the XtremIO array.   If HP used their 900GB eMLC drives how would that change the cost , capacity and rack space discussion  above ?


 Why does HP offer both eLMC and cMLC drives in their 7450?   What kind of advantages does your eMLC have over you cMLC drives?    If there is no advantage then why do you offer different types of flash drives? 


Does HP provide the same warranty on both types of drives?



Do you factor in the Support when comparing the two offerings... ?





@bruins_fan - apologies for the delay as I missed your comment between my Spring Break and now.  Here are your questions and my responses:


Why is HP comparing their cMLC drives vs. eMLC drives that are in the XtremIO array?   If HP used their 900GB eMLC drives how would that change the cost, capacity and rack space discussion above?


The 1.92TB cMLC SSDs are ideal for SAP HANA environments because of their high capacity, excellent performance and outstanding $/GB value. We also have MLC drives in our portfolio and both drives types are able to deliver the performance and resiliency requirements of SAP HANA but we think that cMLC SSDs offer an advantage over more expensive MLC SSDs. You might consider asking EMC why XtremIO is incapable of using cMLC drives.


Even with a comparison using 920GB MLC drives the HP 3PAR StoreServ would still best the XtremIO with its 800GB eMLC drives as the X-Brick controllers, the battery backup units and the Infiniband switches all consume rack space which could otherwise be used to store data.


Why does HP offer both eMLC and cMLC drives in their 7450?   What kind of advantages does your eMLC have over you cMLC drives? If there is no advantage then why do you offer different types of flash drives?


We offer MLC and cMLC drives for the same reason that HDDs are offered in 15k RPM and 10K RPM variants. The choice of drive technology is related to the application workload and the cMLC drives are capable of handling the I/O density generated by SAP HANA so MLC drives are not necessary.


With both drive types HP is able to provide customers with both performance and endurance (backed by 5 year warranty) due to the 3PAR architecture (wide striping, adaptive sparing, etc.) Check out "Worried about flash media wear-out? It’s never a problem with HP 3PAR StoreServ!" and also "cMLC SSDs in HP 3PAR StoreServ: Embrace with confidence".


Does HP provide the same warranty on both types of drives?

All new SSDs on any HP 3PAR system have a 5-year warranty, unconditional. This covers both failures and wear outs. 


Do you factor in the Support when comparing the two offerings...?

Support is included -- 3 year Proactive Care 24x7 for 3PAR systems and 3 year Premium support for XtremIO

We all understand the impact of garbage collection, why HP not countering the fact on ExtremIO's non-system level garbage collection?


Your test on fresh drive will not reflecting correctly on the long run, as the garbage collection has not kicked in. I would assume it will run into unpredictable performance compare to the consistency and predictable performance on XtremIO, as their non-system level gargabe collection work really well.


I would like to see your arguement on this.
