Intel VROC onboard RAID

Intel VROC (Virtual RAID on CPU) is a feature of the Intel processor that enables RAID support.

There are two separate functions of VROC in the HS350X V3:

• Intel VROC SATA RAID, formerly known as Intel RSTe
• Intel VROC NVMe RAID

VROC SATA RAID (RSTe) is available and supported with all SATA drives, both SATA SSDs and SATA HDDs. It offers a 6 Gb/s connection to each drive and on the HS350X V3 implements RAID levels 0 and 1. RAID 1 is limited to 2 drives per array. Hot-spare functionality is also supported.

VROC NVMe RAID offers RAID support for any NVMe drives directly connected to the ports on the server's system board. On the HS350X V3, it implements RAID levels 0, 1, 5, and 10. RAID 1 is limited to 2 drives per array, and RAID 10 is limited to 4 drives per array. Hot-spare functionality is also supported.

The following options are available as follows:

• VROC NVMe RAID on the HS350X V3 by default is disabled and does not support NVMe RAID. In configurator selecting "none" would mean default, same as JBOD. 
• Selecting VROC Standard, feature code to support  RAID-0/1/10.
• Selecting VROC Premium, feature code to support RAID-0/1/5/10.

VROC Standard or Premium are fulfilled as a Feature on Demand (FoD) license.

VROC Premium is only needed on the HS350X V3 for RAID-5 support with NVMe drives. You do not need the VROC Premium license upgrade under any of the following conditions:

• If you have SATA drives connected to the onboard SATA ports, you do not need VROC Premium.
• If you are using RAID 0, 1 or 10 with NVMe drives, you do not need VROC Premium.
• Limitation: Bootable OS RAID volume can’t cross VMD controller.
• VROC is only supported in UEFI mode.

The HS350X V3 offers a variety of controller options for internal drives:

• For 2.5-inch and 3.5-inch drives:

  • Onboard NVMe ports with software RAID support (Intel VROC NVMe RAID)
  • RAID adapters and HBAs for SAS/SATA drives (PCIe slot-based)
  • RAID adapters and HBAs for SAS/SATA drives (cabled in a dedicated space)
• For M.2 drives internal to the server (see M.2 drives section)
  • SATA controller integrated on the M.2 adapters
  • NVMe controller integrated on the M.2 adapters (Intel VROC for RAID)

The following table lists the adapters used for the internal storage of the server.

Configuration notes:

• Supercap support limits the number of RAID adapters installable: RAID 9350 and 940 adapters include a power module (supercap) to power the flash memory. The server supports between 1 and 4 supercaps depending on the server configuration. The number of supercaps supported also determines the maximum number of RAID adapters with flash that can be installed in the server. Make sure SuperCap and cable are selected along with C0YN adapter.

Examples of region-specific warranty terms are second or longer business day parts delivery or parts-only base warranty.

If warranty terms and conditions include onsite labor for repair or replacement of parts, Lenovo will dispatch a service technician to the customer site to perform the replacement. Onsite labor under base warranty is limited to labor for replacement of parts that have been determined to be field-replaceable units (FRUs). Parts that are determined to be customer-replaceable units (CRUs) do not include onsite labor under base warranty.

If warranty terms include parts-only base warranty, Lenovo is responsible for delivering only replacement parts that are under base warranty (including FRUs) that will be sent to a requested location for self-service. Parts-only service does not include a service technician being dispatched onsite. Parts must be changed at customer’s own cost and labor and defective parts must be returned following the instructions supplied with the spare parts.

Lenovo Services is a dedicated partner to your success. Our goal is to reduce your capital outlays, mitigate your IT risks, and accelerate your time to productivity.

Here’s a more in-depth look at what we can do for you:

• Asset Recovery Services

  Asset Recovery Services (ARS) helps customers recover the maximum value from their end-of-life equipment in a cost-effective and secure way. On top of simplifying the transition from old to new equipment, ARS mitigates environmental and data security risks associated with data center equipment disposal. Lenovo ARS is a cash-back solution for equipment based on its remaining market value, yielding maximum value from aging assets and lowering total cost of ownership for your customers. For more information, see the ARS page, https://lenovopress.com/lp1266-reduce-e-waste-and-grow-your-bottom-line-with-lenovo-ars.

• Assessment Services

  An Assessment helps solve your IT challenges through an onsite, multi-day session with a Lenovo technology expert. We perform a tools-based assessment which provides a comprehensive and thorough review of a company's environment and technology systems. In addition to the technology based functional requirements, the consultant also discusses and records the non-functional business requirements, challenges, and constraints. Assessments help organizations like yours, no matter how large or small, get a better return on your IT investment and overcome challenges in the ever-changing technology landscape.

• Design Services

  Professional Services consultants perform infrastructure design and implementation planning to support your strategy. The high-level architectures provided by the assessment service are turned into low level designs and wiring diagrams, which are reviewed and approved prior to implementation. The implementation plan will demonstrate an outcome-based proposal to provide business capabilities through infrastructure with a risk-mitigated project plan.

• Basic Hardware Installation

  Lenovo experts can seamlessly manage the physical installation of your server, storage, or networking hardware. Working at a time convenient for you (business hours or off shift), the technician will unpack and inspect the systems on your site, install options, mount in a rack cabinet, connect to power and network, check and update firmware to the latest levels, verify operation, and dispose of the packaging, allowing your team to focus on other priorities.

• Deployment Services

  When investing in new IT infrastructures, you need to ensure your business will see quick time to value with little to no disruption. Lenovo deployments are designed by development and engineering teams who know our Products & Solutions better than anyone else, and our technicians own the process from delivery to completion. Lenovo will conduct remote preparation and planning, configure & integrate systems, validate systems, verify and update appliance firmware, train on administrative tasks, and provide post-deployment documentation. Customer’s IT teams leverage our skills to enable IT staff to transform with higher level roles and tasks.

• Integration, Migration, and Expansion Services

  Move existing physical & virtual workloads easily, or determine technical requirements to support increased workloads while maximizing performance. Includes tuning, validation, and documenting ongoing run processes. Leverage migration assessment planning documents to perform necessary migrations.
