The PowerEdge T140 supports 4 x 3.5-inch cabled hard drive configuration. The T140 will offer “Entry” as well as “Enterprise” hard
drives. It is extremely important to set customer expectations around proper usage. Using Entry drives in improper usage pattern will
result in risk to smooth operation and customer satisfaction. It is key to select the hard drive class that balances customer budget,
performance and reliability, and that delivers worry-free computing and complete satisfaction.
Recommend/select Entry level hard drives vs. Enterprise level hard drives based on customer usage pattern:
•
Entry drives are designed for customer applications with less intensive workload rating
•
Entry level hard drives are designed for a 8x5 days/week operation
•
Enterprise level hard drives are designed for a 24x7 operating environment
Entry level hard drive restrictions
•
Entry level hard drives and Enterprise level hard drives cannot be mixed
•
Cannot be ordered with Software Raid or Hardware Raid. Must be selected in a NO RAID configuration
•
Must not be used if the customer usage patterns require a workload rating that exceeds 55 TB/year
•
May induce compatibility issues depending on the OS due to the“advanced format”
•
Entry level SATA hard drives in PowerEdge systems carry lesser of either a 1-year limited hardware warranty or the length of the
limited hardware warranty for the Dell EMC system with which the hard drive is shipped.
