Huawei offers OceanStor Dorado, an all-flash storage system boasting a wide range of applications and versatility to meet the needs SMBs, larger enterprises, or vertical industry applications.
We connect the Huawei OceanStor SAN device directly to the Huawei Fushion Servers, without using the SAN Switch, with 16 HBA cards in MESH topology. Each of the two controllers has four 16 HBA inputs under the name of SMART IO. In addition, there are two 8 GB extension ports. VMware virtual machines are running on hosts. Our ERP applications, critical DBs, and business applications are running in these. Again, we use another SAN under a different cluster in the disaster recovery section.
Solidfire is a good, multi-purpose array for iSCSI environments. Grid architecture allows incremental, linear expansion of the array both in capacity and performance. The all-flash is a very high performance, low latency platform for a lot of applications. The way the company has architected the platform allows for continual upgrades and removes the lift-and-load replacements if you stay with Solidfire in the future. The Solidfire fiber channel implementation is workable, but largely there is a checkbox. I cannot imagine any fiber channel shop is going to look at a Solidfire seriously, unless they are looking to move towards Ethernet based transport. Write intensive workloads struggle on the array. The double-helix data protection combined with the architecture can make writes more latent than expected - well into the teens and 20's of ms within the array.
When purchasing support for your Huawei OceanStor system, there are two support options offered by Huawei (i.e. Hi-Care and Co-Care). Huawei Hi-Care service is when Huawei responds to your technical requests for remote troubleshooting and advance hardware replacement in the shortest possible time. Hi-Care provides onsite technical support to help you maintain a more efficient and stable network environment and improve network productivity. Whereas, Huawei Co-Care service is a collaborative solution delivered by Huawei certified partners. Depending on the capability of your Huawei support partners, I would recommend Hi-Care for mission-critical environments since this ensures Huawei takes responsibility for meeting the support SLAs. If you have very capable Huawei support partners, then Co-care could be a more cost-effective support option.
When we have had problems, the response on the Solidfire side has been strong, but not perfect. As they scale and integrate into NetApp, support from regions outside of the USA are having a more difficult time diagnosing and addressing issues for complex problems. The Boulder, CO, and Raleigh, NC, support teams are both extremely strong and provide top-notch support. ActiveIQ is a great support tool both for NetApp/Solidfire and for the customer. The proactive support tickets opened have been helpful. The node-based support has been excellent - meaning when we had a DIMM fail, they sent a replacement node - no time consuming troubleshooting of internal components to fix the issue. Upgrades are handled by SF technicians, so it feels white-glove
All Flash NVMe SSD technology is currently at the top of this business. Its disk structure is hundreds of times faster than traditional mechanical SAS systems, but also compared to today's SSD systems! It has a much more affordable price than the devices of the same class. In addition to these, we had a lot of hesitation when we decided to give up the competitor brand and buy a product that works reliably and smoothly, but we researched and learned very well. We made the right choice.
SolidFire was chosen over these other service providers because of relationships we have with the company, with our reps, and with the local Denver presence. We also are a partner, and we felt that the solution stacked up technologically very well against the competition and was more cost effective.
