SLOB Use Cases By Industry Vendors. Learn SLOB, Speak The Experts’ Language.

Introduction

This is just a quick blog entry to showcase a few of the publications from IT vendors showcasing SLOB. SLOB allows performance engineers to speak in short sentences. As I’ve pointed out before, SLOB is not used to test how well Oracle handles transaction. If you are worried that Oracle cannot handle transactions then you have bigger problems than what can be tested with SLOB. SLOB is how you test whether–or how well–a platform can satisfy SQL-driven database physical I/O.

SLOB testing is not at all like using a transactional test kit (e.g., TPC-C). Transactional test kits are, first and foremost, Oracle intrinsic code testing kits (the code of the server itself). Here again I say if you are questioning (testing) Oracle code then something is really wrong. Sure, transactional kits can involve physical I/O but the ratio of CPU utilization to physical I/O is generally not conducive to testing even mid-range modern storage without massive compute capability.

Recent SLOB testing on top-bin Broadwell Xeons (E5-2699v4) show that each core is able to drive over 50,000 physical read IOPS (db file sequential read).  On the contrary 50,000 IOPS is about what one would expect from over a dozen of such cores with a transactional test kit because the CPU is being used to execute Oracle intrinsic transaction code paths and, indeed, some sundry I/O.

SLOB Use Cases By IT Vendors

The following are links and screenshots from the likes of DellEMC, HPE, Nutanix, NetApp, Pure Storage, IBM and Nimble Storage showing some of their SLOB use cases. Generally speaking, if you are shopping for modern storage–optimized for Oracle Database–you should expect to see SLOB results.

The first case is VMware showcasing VSAN with Oracle using SLOB at: https://blogs.vmware.com/apps/2016/08/oracle-12c-oltp-dss-workloads-flash-virtual-san-6-2.html.

VMware has an additional publication showing SLOB results at the following URL: https://blogs.vmware.com/virtualblocks/2016/08/22/oracle-12c-oltp-dss-workloads-flash-virtual-san-6-2/

The VCE Solution guide for consolidating databases includes proof points based on SLOB testing at the following link: http://www.vce.com/asset/documents/oracle-sap-sql-on-vblock-540-solutions-guide.pdf.

When searching the NetApp main webpage I find 11 articles that offer SLOB testing results:

Hewlett-Packard Enterprise offers an article entitled HPE 3PAR All-Flash Acceleration for Oracle ASM Preferred Reads which models performance using SLOB. The article can be found here: http://h20195.www2.hpe.com/V2/getpdf.aspx/4AA6-3375ENW.pdf?ver=1.0

I also find it interesting that folks contributing code to the Linux Kernel include SLOB results showing value of their contributions such as here: http://lkml.iu.edu/hypermail/linux/kernel/1302.2/01524.html.

DellEMC has many publications showcasing SLOB results. This reference, however, merely suggests the best-practice of involving SLOB testing before going into production:

Non-Vendor References

Although not a vendor, it deserves mention that Greg Shultz of Server StorageIO and UnlimitedIO LLC lists SLOB alongside other platform and I/O testing toolkits. Greg’s exhaustive list can be found here: http://storageioblog.com/server-and-storage-io-benchmarking-resources/.

Summary

More and more people are using SLOB. If you are into Oracle Database platform performance I think you should join the club! Maybe you’ll even take interest in joining the Twitter SLOB list: https://twitter.com/kevinclosson/lists/slob-community.

Get SLOB, use SLOB!
