Cisco FlexPod vs. Oracle Exadata

FlexPod is great for mid to large size companies, where the flexibility and depth of a traditional SAN and high performance servers is required. For smaller companies, it might make more sense to go with a hyper converged solution such as Hyperflex or Nutanix (both of which can still run on Cisco UCS servers, but would not be making use of Netapp storage), to meet the requirements in a smaller footprint.

Oracle Exadata is well-suited for environments where massive performance for Oracle databases is required. Storage indexes reduce the unnecessary I/O. Smart Flash
Cache accelerates random reads/writes.

Our OLTP application demands very high concurrency. Multi-node Exadata provides high availability and zero downtime during DB patching. It comes with lots of built-in automations, so it reduces many routine tasks for sysadmins, like network, storage, and VM configuration, and it also reduces many Oracle DBA tasks, like Oracle software installation, patching, and upgrades.

• Single Pane of Glass Server Administration.
• Ease of firmware upgrades.
• Incredible support when you have an issue. The Cisco/NetApp/VMware FlexPod support teams work together and drive your issues down to the root cause.

• Oracle Database : Deliver industry-leading security, high availability and scalability with Oracle Database, which has been significantly enhanced to take advantage of the Oracle Exadata Storage Servers.
• Exadata Smart Scan : Improve query performance by offloading intensive query processing and data mining scoring to scalable intelligent storage servers.
• Smart Flash Cache : Transparently cache 'hot' read and write data to fast solid-state storage, improving query response times and throughput. Exadata systems use the latest PCI flash technology rather than flash disks. PCI flash delivers ultra-high performance by placing flash directly on the high speed PCI bus rather than behind slow disk controllers.
• Hybrid Columnar Compression : Reduce the size of data warehousing tables by 10x, and archive tables by 50x, to improve performance and lower storage costs for primary, standby, and backup databases. Query high, query low, archive high and archive low.
• Infiniband Network : Connect multiple Oracle Exadata Database Machines using the InfiniBand fabric to form a larger single system image configuration. Each InfiniBand link provides 40 Gigabits of bandwidth–many times higher than traditional storage or server networks.
• Petabyte Scalability : Easily scale data warehouse to support enterprise data growth.

• KVM control of the blades still requires Java. Avocent is using HTML5 now, and it would be nice if the KVM console for these UCS blades could too.
• Price - Like any Cisco product, there are cheaper options. They aren't nearly as fully featured, but at times, it would be nice if UCS could be a bit cheaper.

Incentivized

• The process of patching and upgrade of Exadata server components could be improved with a goal to minimize the overall effort, make it fully automated and transparent.
• Improved guidelines and possibly more sophisticated tools for sizing of new Exadata servers for migration from old legacy hardware.

I am comparing Exadata with the Oracle RAC database experience. In addition to Oracle RAC features, Exadata provides automatic performance optimization through Smart Scan and storage indexes. Deep integration with the Oracle ecosystem and tight coupling with Oracle Enterprise Manager
for monitoring and management. Some downsides of Exadata are: a steep learning curve, concepts like cell offloading, IORM, and flash cache behavior aren’t intuitive initially. Operating
Exadata requires specialized DBA skills.

Being a Cisco shop already it was a natural fit to go with a solution based on their technology. Then add in VMware which we are were already using - that was two out of the three for the FlexPod. Then factor in NetApp's de-duplication technology and flexibility in configuration and options and it's a match made in heaven. Not to say we haven't had some stumbles and some issues but it works and it works well.

Oracle Exadata Database Machine had the best performance overall hands down. It clearly beat the competition and we were seeing 1000X improvement on SAP HANA. Oracle Exadata Database Machine beat that without us refactoring our code. To achieve that in HANA, we had to refactor the code somewhat. Now this was for our limited POC of 5 use cases. Given the large number of stored procedures we had in Sybase, we need to capture more production metrics but we are seeing incredible performance.

• FlexPod has allowed our team to be extremely quick to resopnd to new VM build requests. The amount of RAM, CPU and backplane offered by B series blades allows us to go with very high VM density. The quick deployment of service profile templates also means that when we have to add new hosts, it is done quicker.
• FlexPod and the service profile portability (along with VMware) has allowed for full upgrades and migrations from M1/M2 series hardware to M4 hardware without any downtime or outages to the clients. Blades can be moved into new chassis, or service profiles moved to new generation blades, with no impact to the customers' ability to work.

• Single support from a single vendor with both machine and database from Oracle, which is costing us less.
• With Exadata, we need less technical manpower and less technical support. A business transaction with the integrated and centralized database helps us focus on other business needs.
• We don't need to buy additional licenses and Hardware for the next 3 to 5 years.
