Only way it could be possible to use TRIM is to configure disks as passthroug and use software RAID in compliant OS.<br />
No RAID controller yet supports TRIM to disks or to host.

Thank you for your support guys

The RAID Management software may expose TRIM settings in the console.<br />
<br />
We work with Intel based RAID (LSI) and we do see TRIM settings.<br />
<br />
That being said, we _never_ touch TRIM, UNMAP, and other such SSD focused settings unless absolutely necessary.<br />
<br />
The only time we've had to look at either has been when the manufacturer claimed Storage Spaces compatibility (multiple SSD drives in one or more JBODs) but their drives utterly failed or required UNMAP tweaking to at least stay in the Pool (bad firmware).

I would like to enable TRIM on SSD drivers.<br />
Do I have to enable TRIM on physical host (SAS drivers) or only on VM machine (SSD storage drivers)<br />
<br />
My server spec. <br />
Dell R630 controller Perc 730P - Windows 2012 STD<br />
<br />
- OS:: 3x 300GB 15K: Raid and 1 drive configured as a hotpsare<br />
- Storage for VM (SQL 2014):: 7x 500GB SSD RAID 50 and 1x drive configured as a hotspare.<br />

Thanks,

Enable TRIM on Host with SAS drivers and SSD storage

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality. Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning.
