Oracle Oracle Exadata X5 Administration
Oracle introduced the next era of its engineered systems with the largest ever software update to Exadata. Oracle releases a unique technology each 12 to 15 months and while or not it's referred to as X5, the brand unique fashions are in reality the sixth technology of Oracle engineered techniques. To hold song of everything new, birthright here is a quick ebook to Oracle Exadata X5.
Hardware: Hardware changes for Exadata X5 consist of compute processors for the two core database servers that retrograde up to 18 cores and both-socket core remembrance capability with 768 GB maximum. The ingenious two core database servers now beget an eight core optimum and the capability to optimize for capacity with disk and glint -- now with twice the glint -- or for I/O effectivity with entire flash.
Elastic configuration: The massive exchange comes with elastic configuration, which means that you can scale out one server at a time, instead of having to purchase several sized modules. companies can add X5 servers one by one to an X5 machine or add them to outdated generations of Exadata, additionally one after the other. This makes it less complicated to tailor Exadata to selected initiatives, akin to in-reminiscence, flash, or storage. as an example, to create an Exadata desktop designed for in-memory, add compute servers with the optimum remembrance potential mixed with the mix of glint and disk.
utility: Exadata X5 duplicates records in-memory, a characteristic Oracle calls a first. This creates in-reminiscence failing tolerance. Exadata X5 moreover has what Oracle calls the "world's first facts-remodeling glint cache," in which the smart glint Cache automatically transforms Hybrid Columnar Compression records into absolute columnar facts. Exadata X5 additionally has the first virtualized InfiniBand platform and the primary direct-to-wire InfiniBand OLTP protocol.
Licensing: Exadata X5 has just a limited distinctive digital machine (VM) licensing protocols as smartly. depended on Partitions allows for clients to license by means of VM as opposed to by means of server. moreover, to succor with licensing fees, the X5 means that you can flip off any CPUs you aren't using and then flip them lower back on when they're needed.

Iron Man uses Exadata (Image Source — https://goo.gl/Mwt8mA)
Whenever I used to hear this term called as “Exadata” — I’d mediate to myself — What is Exadata anyway? Is it some benign of a database? A storage appliance? An extremely fast server?
I was under the impress that there’s something very knotty and a very technically challenging architecture behind it which probably would breathe course too difficult to understand.
Apparently, I was right! ;)
When I started working first with Exadata, in my first consulting experience, my learning curve was fairly precipitous and I had to grasp complexities of the project quickly, understand and implement Exadata with a team of DBAs deployed at an aviation client’s environment.
It could breathe with your case that you’re currently a DBA and your client may or may not beget an Exadata environment. They as DBAs always beget an itch to learn and try something unique every time there’s a unique feature, version or even a product is announced. Thankfully, I had the opening to play with Exadata thus I decided to win my hands dirty.
Disclaimer — Please win used to the following terms when you’re learning Exadata for the first time — they can breathe used interchangeably to characterize the Exadata components (wink wink) — “extreme”,”smart”,”intelligent”,”flash”
Before I abysmal dive into architectural components and how and why things beget been setup the course they are in Exadata, I’d like to confess that I’m still learning my around with this mammoth of a machine. It’s fairly consuming to discern the evolution of Exadata with time.
<history>- Exadata is an offshoot of Storage Appliance for Grid Environments(SAGE) project, the working name for Oracle Exadata Database Machine, began about three years before the product’s final release in 2008. It’s a database machine designed by Oracle to hasten Oracle database software and is a combination of compute (database) and storage systems. Starting with version X1, Exadata has arrive a long way! </history>
In any typical bare-metal server, the ROI on investments basically depends on how mercurial can you serve your clients through your applications. For this you definitely necessity a robust IT infrastructure, most of the servers which are there as of now ensue the scale-up architecture, but Exadata follows scale-out architecture. Since everything boils down to one word “performance”.
I am skipping the hardware configuration Part of Exadata, since Oracle itself has shared a lot of information on the current hardware configuration here for Exadata X-6 — http://www.oracle.com/technetwork/database/exadata/exadata-x6-2-ds-2968790.pdf.
The latest version of Exadata that has been released is X-6. X-6 offers umpteen benefits compared to it’s predecessors, just sustain in intellect that it’s moreover an expensive investment. https://cloud.oracle.com/database/exadata/pricing. Just cautionary charge sharing. :)
Exadata is made up following components –
1) Database Servers aka Compute Nodes — where Oracle database resides.
2) Exadata Storage Cells aka Storage Nodes — uses a command line utility called as CellCLI to manage storage.
3) InfiniBand switches — for elevated precipitate (read extreme) connectivity between storage and database servers.
4) PDU and Ethernet Switches — Extra PDUs (Power Distribution Units) in case of any failure for the sake of redundancy.
(Image Source — https://goo.gl/QSlULs)
Initially, Exadata offered two flavours of Exadata Storage servers — High Performance and elevated Capacity but after X5, they changed to elevated Performance and Extreme glint storage.
The advantage of Exadata Storage server Extreme glint is that it’s performance is orders of magnitude faster than traditional storage array architectures, and is moreover much faster than current all-flash storage arrays. Oracle moreover guarantees that the performance of extreme glint won’t wean off with time.
Now, let’s understand what benign of things to expect when you start working on Oracle Exadata database machine for the first time. In the Database Servers aka Compute Nodes beget following software components pre-configured when you win the brand unique rack installed on your premises -
1) OS (Oracle Enterprise Linux Flavour)
2) Oracle Home (has 2 primary homes — one for the database and another for the grid infrastructure)
3) RAC and ASM pre-configured
4) DBFS for sharing the file system for Oracle internal files
In the Exadata Storage Cells or Servers beget following software components pre-configured -
1) OS (Oracle Enterprise Linux Flavour)
2) CELLSRV (Cell Server)
3) Management Server (MS)
4) Restart Server (RS)
Following X-5, Oracle introduced Exadata with Extreme Smart glint Cache. With the X5s, you necessity to choose between the elevated Capacity and elevated Performance cells with regards to the number of glint cards which arrive with the configuration. Since the X5s elevated Performance Storage Servers conclude not beget any hard disks for database storage, the glint devices will breathe used to store database files persistently in addition to acting as a storage layer cache for the RDBMS layer I/O requests.
<MagicSauce> iDB protocol — Oracle developed the iDB protocol to hasten across the InfiniBand network. The iDB protocol is not available to databases running on non-Exadata hardware. iDB is mainly used for predicate filtering which is the cherry on top offering for query offloading . The iDB protocol used to interact with the Exadata storage cells includes the predicate information in its requests, predicate filtering is accomplished by performing the standard filtering operations at the storage smooth before returning the data. entire ASM disks on Exadata are accessed via the iDB protocol. </MagicSauce>
I’d argue the advantages of Oracle Exadata where it scores the most and why you or your client can retrograde ahead with Exadata as an investment for your business.
1) Time to Market — This is something that every IT organization deals with, from the project kick-off till it’s implementation and production takes a long time. Exadata as being an engineered system which is pre-configured before it’s delivered to you. It does cease up saving many man hours on setting up the infrastructure. Also, Exadata can house entire your PROD/DEV/TEST environments into one.
2) RAC Ready — Exadata comes pre-configured with ASM and RAC, which saves your DBA’s time to configure everything from scratch.
3) unique Vendor — “The buck stops here.” Oracle owns the gross stack so there cannot breathe and will not breathe any failing game when there’s any issue. So whether it’s database, hardware or any network issue, Oracle is amenable for 100% of it.
Lastly, as I am myself preparing for Exadata Certification, I’d like to partake that thankfully, Exadata certification track does not yet require one to beget a prior OCA/OCP certification. Currently, Oracle University provides training on X-6 machine, but the Exadata exam as of now can breathe taken on X-3, X-4 and X-5 administration. More information available here -http://education.oracle.com/pls/web_prod-plq-dad/ou_product_category.getPageCert?p_cat_id=212
Hope this information helped you win off the ground regarding what and why of Oracle Exadata.
Please conclude partake your feedback or just partake your experience with this mammoth of a machine, would affection to hear from you. Thank you for reading thus far. please pat yourself on the back! :)
In a bid to boost its hardware sales, Oracle is now going directly after the core two-socket server market in the data focus with its line of engineered systems, courtesy of a unique X5 generation of the Oracle Virtual Compute Appliance and other integrated appliances.
Up to this point, Oracle primarily has focused on higher-end and more specialized integrated systems like Exadata and Exalytics, which Tim Shetler, vice president of Exadata product management at the company, described in an interview as "systems built for one task." To try to atomize in to the mainstream two-socket server business, Oracle will tap its lesser-known and more general-purpose engineered systems.
"We've never really competed for the focus core," said Larry Ellison, Oracle's chairman and CTO, at a press conference in Redwood Shores, Calif., on Jan. 21. Doing so requires a unique strategy, Ellison added -- and that strategy centers on the Virtual Compute Appliance (VCA), one of the upgraded systems announced by Oracle as Part of the X5 family.
An appliance for entire purposes
According to Shetler, the Oracle VCA is designed to conclude "whatever you want" in data processing. The VCA X5 is scalable from two to 25 compute nodes in a unique rack, using Oracle's latest two-socket servers based on Intel Xeon processors. It has a 19.2 TB aggregate remembrance capacity and supports Windows, Solaris and Linux applications. A unique feature that comes with the latest-generation product is a option between entire glint storage and options that mix hard disks and glint devices. That allows some customization in balancing the necessity for elevated performance versus storage capacity.
The X5 version of the appliance moreover runs its internal networking entirely on InfiniBand, which Ellison said is newer, faster and more reliable than vie technologies Ethernet and Fibre Channel. InfiniBand supports guaranteed in-order packet delivery, and Ellison celebrated that the network built into the appliance is entirely defined by software. "You wire this thing once, and then if you want to add more nodes you reconfigure and expand by changing the parameters in a file," he said. "You wire once and you're done."
The VCA X5 is intended to breathe paired with Oracle's FS1-2 glint storage system, an upgraded storage locality network device that was announced at the selfsame time. The FS1-2 is based on a highly available scale-out architecture -- it supports up to 16 elevated availability nodes, 912 TB of glint capacity and 2.9 PB of glint and disk combined, and 10:1 data compression. Using the maximum all-flash configuration with the VCA X5, the FS1-2 can ply up to two million I/O operations per second with a equipoise of 50% reads and 50% writes, Oracle said.
Oracle's unique math on server, storage costs
On cost, Ellison compared the VCA X5 to what he considers to breathe its closest competitor, Cisco's Unified Computing System (UCS) platform with that company's M4 blade servers. Looking to demonstrate that Oracle has the less expensive machine on both hardware and software, Ellison claimed that the differences in charge were $450,000 and $220,000, respectively, for similar configurations of the VCA and UCS systems with 27 servers and 972 processor cores. That is the largest, and most expensive, practicable option on the Oracle side.
He did the selfsame benign of comparison between the FS1-2 and EMC's VNX 8000 storage system, showing a charge incompatibility of $630,000 for a configuration with 15.6 TB of glint storage and 192 TB of disk. Ellison said that in the two-socket server industry, the course to win is to beget the lowest charge -- and that having it is Oracle's unique mantra.
Oracle has always prided itself more on elevated performance than low prices, so why the sudden stress on cost savings for customers? Ellison said he was "tired of having this argument" about whether or not Oracle is a low-cost vendor. Without disclosing details, Shetler acknowledged that the charge of the Oracle Virtual Compute Appliance has decreased -- but he said it and Oracle's other general-purpose engineered systems beget always been less expensive than the competition.
"That's really been lost in the shuffle," Shetler said. "People beget just generally seen Oracle as more expensive." But, he added, the company offers "a broad range" of systems. "It's not just about the elevated end."
R "Ray" Wang, founder and principal analyst at Constellation Research Inc., said the strategy minute by Ellison isn't entirely new. The VCA X5 is "the über-appliance Larry's always wanted to deliver," Wang said.
