XtremIO Solutions and Design Specialist Exam for Technology Architects (E20-526) - EMC

Proceed with filesystem aging by doing random overwrite cycles.

The volume size must be specified in MB, GB, TB, and not in KB.

IOPs.<br />
Second write workload IOPS = 2 GB/s divided by 128 kB = 2 x1,073,741,824 / (128 x 1,024) = 16384<br />
Total IOPS required would be 150,000, from the first workload, plus 16384, totaling 166384.<br />
A 2 X-Brick cluster provides 300K Read/write IOPS so it would be adequate. Storage capacity and performance scale linearly, such that two X-Bricks supply twice the IOPS, four X- Bricks supply four times the IOPS, six X-Bricks supply six times the IOPS and eight X-Bricks supply eight times the IOPS of the single X-Brick configuration.<br />
<br />
Note: Choose an EMC XtremIO system and scale out linearly by adding more XtremIO X-Bricks.<br />

The XtremIO's RESTful API allows HTTPS-based interface for automation, orchestration, query and provisioning of the system. With the API, third party applications can be used to control and fully administer the array. Normally you would access the API using some form of programming/scripting language, such as<br />
Python or Perl. However for the purposes of learning or testing concepts there are a number of tools<br />
that work better, such as HTTPRrequester and curl.<br />
<br />
* Curl is a command-line tool that exists in all Linux distributions, and is available for most other Unix<br />
OSes as well as Windows. To use curl to access XtremIO you’ll need to pass it a few options, such as the username/password to access the array (any valid account on the XtremIO XMS will work), the URL of the API, and potentially a few options such as -k to tell curl not to validate the SSL certificate (presuming you don’t have a valid certificate installed), and -s (silent) to stop curl displaying it’s progress as it downloads<br />
<br />
* HTTPRequester is a browser extension that is available for both Chrome and Firefox.<br />
the response. As with for curl, you’ll need to provide a username/password, which is done by clicking on the “Authentication…” box, which adds two boxes below the URL for the username and the password.<br />

From the menu bar, the Inventory icon is to be clicked to display the Inventory workspace. This<br />
workspace takes the place of the Hardware workspace in earlier versions of the XtremIO GUI. With the All Clusters tab selected, we can see a list of all the hardware elements in the managed clusters.<br />

<br />
Note: With time, additional clusters can be added to a deployed XMS. In addition, a cluster can be easily moved from one XMS to another. All management interfaces (GUI/CLI/REST) offer inherent multi-cluster management capabilities. Multiple cluster management is supported from version 4.0 and up. https://community.emc.com/community/connect/everything_oracle/blog/2015/08/27/xtremio-40-<br />
