Future-defined server hardware that simplifies storage at the edge
An efficient, low cost storage solution that has the flexibility to scale with demand is something all organizations should be striving to achieve. No-one should be paying more than they need to for their storage infrastructure and its ongoing operation and maintenance, regardless of their performance requirements. It is with this in mind that StorMagic and Lenovo have partnered to provide a range of solutions for the cost-conscious storage architect that don’t compromise on performance and enable hyperconvergence. This data sheet details these solutions which leverage Lenovo’s ThinkSystem range of rack servers alongside StorMagic SvSAN.
High performance without the high costs
The partnership between StorMagic and Lenovo covers all of Lenovo’s ThinkSystem rack servers, however this data sheet deals with the three most commonly deployed models. The joint solution combines Lenovo’s renowned server performance and reliability with StorMagic SvSAN’s storage high availability and simplicity. The two deliver a full solution which provides low-cost, lightweight storage and is therefore ideally suited for edge computing and remote site locations, or SME data center deployments.
Future-defined server hardware
ThinkSystem servers are purpose-built to deliver performance, security and agility in an open environment that won’t limit options in future. With developments in IoT and artificial intelligence likely to increase the strain on IT infrastructure outside of the data center, organizations need hardware that can easily meet new challenges. Lenovo rack servers offer the unmatched value, flexibility and industry-leading efficiency to meet mission-critical demands with legendary quality and reliability.

Simplifying storage at the edge
SvSAN is the virtual SAN that makes the complex world of virtualized storage simple. Perfect for edge computing environments, the technology is based on software-defined storage that eliminates the need for physical SANs. SvSAN is designed to be very simple to install and manage whether deployed as part of a hyperconverged solution or as a storage-only target for any Lenovo server. SvSAN has very low system hardware requirements, centralized management/deployment and an incredibly lightweight witness that tolerates low bandwidth, high latency links and is completely separate from the server cluster. The witness allows for the creation of genuine 2-node highly available clusters, or 3-node clusters that can withstand an offline server due to either failure or maintenance and still maintain high availability.
The following table illustrates SvSAN’s minimum hardware requirements:
|CPU||1 x virtual CPU core1
• 2GHz or higher reserved
|Disk||2 x virtual storage devices used by VSA
• 1 x 512MB Boot device
• 1 x 20GB Journal Disk
|Network||1 x 1Gb Ethernet
• Multiple interfaces required for resiliency
• 10Gb Ethernet is supported
• Jumbo frames supported
1When using StorSecure to encrypt data, 2+ virtual CPUs are recommended
2Additional RAM may be required when caching is enabled
SvSAN is licensed based on the usable VSA (Virtual Storage Appliance) capacity. License tiers are set at 2TB, 6TB, 12TB and Unlimited TB. SvSAN licenses are perpetual – after a single payment they can be used forever. The only ongoing costs are for support renewal payments.
Furthermore, there are two versions of SvSAN available – Standard Edition and Advanced Edition. The Standard Edition provides all of the features necessary to deliver and manage highly available shared storage, while the Advanced Edition includes additional performance-enhancing features, collectively known as Predictive Storage Caching. The full list of features available in each version are illustrated below.
SvSAN’s integrated encryption and key management solution, StorSecure, is available separately and provides military-grade encryption with a hugely flexible key manager that enables keys to be stored anywhere, whether onsite, in a datacenter, or the cloud.
|Synchronous mirroring / high availability|
|Stretch / metro clusters|
|VSA restore (VMware only)|
|VMware vSphere Storage API (VAAI) support|
|Centralized management and monitoring|
|Multiple VSA GUI deployment and upgrade|
|I/O performance statistics|
|PowerShell script generation|
|Predictive read ahead caching (SSD and memory)|
|Write back caching (SSD)|
The three server models detailed in the table below are the most frequently deployed with SvSAN from the Lenovo ThinkSystem range. However, SvSAN is compatible with all Lenovo servers, giving the storage architect a huge range of possibilities.
