Increase your bottom line. Cut Returns!

Just what does a returned drive cost your company?

Here are a few hard costs involved:

  1. Shipping – shipping the bad drive from the customer back to you, plus shipping a replacement drive back to the customer. Shipping times two. Shipping adds nothing to your bottom line, in fact it takes away. Shipping is expensive, period.
  2. Handling – receiving in the drive, unpacking it, matching up the paperwork, putting the drive through a test and screening process to determine if it really is bad and if so can it be fixed. Einstein proved that Time Equals Money – and once again handling is a negative on your bottom line.
  3. A replacement drive – the bad drive may no longer be in warrantee and so you may need to subtract the cost of another disk drive from your bottom line.
  4. Customer Good-Will – this is probably the most valuable item on this list. You’ve spent years building the good reputation of your company, and years building relationships with your customers. We all know that those relationships can be fragile and certainly must be maintained. Not having your drives fail pays back over and over again when you customer goes to buy more.

How are your returns?

Any returns are a problem. And more returns is a BIG problem. But this problem has a solution.

How would you like to have this to say about your return situation:

“We used to have dozens of drives returned each month. Since setting up testing using the STB Suite our returns have dropped to almost zero. Truthfully, we have had six drives returned in the past 12 months since we began testing using the STB Suite.”

Dozens of returns = bad, expensive, bad customer relations

Six returns in a year = not so bad, not very expensive, customers think highly of you!

 

Why the STB Suite?

We talk with companies all the time who actually don’t test the product they ship!

And we talk to companies who try to test the drives they shipped using free manufacturer-supplied utilities.

And we talk to companies who know they have a return problem but just don’t have the in-house technical expertise to even know where to begin to set up a final test setup. None of these situations is a good one. Not testing or using freeway is a lot like walking across a frozen lake. It may be fine, maybe for a while, but chances are that someday the ice is going to break!

Let us help

We’ve been supplying disk, tape, and jukebox test solutions for over 20 years. Many of our employees come from system integration and drive reselling backgrounds. We understand your goals – you want to ship the highest quality product, in the fastest time, and have the product “stick”.

We’ve helped hundreds of companies, we’re ready to help you!

Let us have 30 minutes of your time to show you how we can help you meet those goals and add to your bottom line.

Custom Reports for DMM in v.8.7

DMM custom logs in v8.7

A powerful new feature in the STB Suite version 8.7 is user customizable reports for DMM. This new feature lets you include any information in the DMM log files.

Per Test-Step information

You can define any information you want printed for each test step by clicking the Advanced Options button and filling in your text in the new Special Text to Log for this Test field. This field is found near the bottom of the Advanced Options page –

As an example we will create a test sequence to run a DoD5220 disk purge operation. As you see in the example above we have defined the text “DoD5220-write pass 1” for the first test step. We will define each of the remaining test steps in the same format.

 

By clicking on the View Test Sequence Details button you can see what special text is defined for each test step –

 

Overall Test information

You can define two new pieces of information for the overall test at runtime, an Operator ID and a general text information. This information can be entered in the Test Loop Count dialog which appears when you click the Start Test button –

View an example of the new DMM log and read the full article here.

 

 

 

Full DMM test list in v.8.7

DMM v8.7 Test List

This article will give a brief description of each predefined test step available in DMM, in STB Suite version 8.7

 

 

Access Methods

In cases of test steps which write or read the drive you will need to define the Access Method you want the test step to use.  The access method is chosen from the list at the top of the Test Setup display

Random, Sequential, Butterfly, CPAM

 

Predefined Test Steps

Verify, Write, Write/Verify, Read, Write/Read, Seek, FW Download, Format, Spin Down/Up, Synchronize, External Program, PList, Glist, User Defined, Clear Log Pages, Save Log Pages, Bus Reset, Drive Selftest, Streaming, OLTP, File Server, Web Server, Workstation, Delay, AdjTkIntf, SMART

 

Drive Info

SCSI/SAS/FC info

The Drive Info test step logs all available drive information to the log file. In the case of SCSI,SAS, or FC drives this information will be retrieved from the drive using a series of INQUIRY commands –
******************************************
Drive INQUIRY information:
Vendor = SEAGATE 
Product = ST3450857SS     
Revision = ES62
Device Type =  Direct Access
Removable Media = No
Dual Port
Width = 8 bit
Queuing Supported
SCSI Level = 5
Serial Number = 3SK00EMN
WWN = 5000C50000798065
Drive Temperature = 22

SATA Info

In the case of SATA drives the test will issue an IDENTIFY command as well as retrieve the SMART data and SMART SELFTEST log data – a large amount of data is logged as shown with some of the data truncated –
SATA IDENTIFY data follows:

Data truncated …

Model Number = ST31000340NS
Serial Number =             9QJ280T5
Firmware Version = AN05
# of Sectors transferred per interrupt = 16
Trusted Computing feature set NOT supported



Drive Temperature = 20

 

SSD Precondition

The SSD Precondition Test prepares a SSD drive for testing or benchmarking by:

  • Writes the entire drive sequential TWICE
  • Takes 1-minute measurements of the performance of the drive for atleast 5 measurements
  • Given a group of 5 measurements, it uses the SNIA definition for when the drive’s performance has reached a “steady state” (definition is contained below)
  • If any group of 5 measurements is NOT in a “steady state”, another group of 5 measurements is taken.  The test completes only when the drive is in a “steady state”

Definition of “Steady State”:
Criteria #1: The maximum of the 5 measurements minus the minimum of the 5 measurements must be less than 20% of the average of the 5 measurements
Criteria #2: After computing the Least Squares Line thru the 5 measurements, the max on this line minus the min on this line must be less than 10% of the average of the 5 measurements.

 

See full descriptions of each test type and drive info here.

 

 

DMM Log Information in v.8.7

DMM v8.7 Log InfoSTB Suite 8.7 features several new pieces of information presented at run-time as well as recorded in the log files.

New Device Display

The device display has been improved to display more information at a glance. Each drive has an individual status line which makes seeing overall test progress much easier –

Drive Status:

Note that it is plain to see which drives are running and which test step each drive is on. The drive shown in yellow with the status “Done with all tests” is a drive which has had testing stopped by the user. The drive shown in violet is paused during test pass 1, and the two drives shown in blue are running, one on test step 1 and the other on test step 3. The check boxes show which drives were selected for testing.

 

Select All drives

Also note – there is a check box next to each adapter in the system. Checking this box will select all drives attached to this adapter. This allows much quicker selection when many drives are attached to each adapter.

Drive Control

Right-clicking on any drive will bring up a list of drive control options –

Each drive can be individually stopped, paused, resumed, etc.

 

Drive Status details

The Get Status choice displays current drive performance metrics along with estimated time to complete, throughput measurements for the selected drive as well as overall aggregate system throughput –

 

New Log File Information

There are many new pieces of information now included in the DMM log files.

Log File Name

Starting with the log file name there is a new option found in the Advanced Options tab  – Add Date-Time to Logfile Name. Checking this option will append the date and time to the log file name –

General Test Run Information

The start of each log file includes information about the test system and test environment –
================================================================================
>> SCSI Toolbox32, Version 8. 7. 0 (build) 130104, running on \\W7TEST        <<
>> Default Driver: 10, Operating System: Windows 7<<
