I don’t know about you, but the thought of using a “server” as a “backup storage” resource may sound a bit odd at first. After this post, you may change your tune. Let’s dig into this a bit.
I’m sure you’ve heard of the Cisco UCS Unified Computing line of servers and their associated Fabric Interconnect technologies. Additionally, you may know that there are M-Series, B-Series and C-Series form factors for the various configuration options that are in high demand for the modern data center. Which reminds me, you should check out this PDF poster of all of the current UCS components; it is my go-to resource to see how the different UCS offerings can be arranged and interconnected.
So let’s zoom in on the Cisco UCS C3160. It has a few key specifications that caught the interest of a number of keen architects in my extended professional networks which led to this notion of putting the C3160 in place as high performance and high capacity backup storage system. The most interesting specification is that the C3160 can hold up to 60 small form factor drives. Two additional small form factor SSD drives are in place for the boot volume. What this means is that these 60 drives can be used as a backup storage repository. RAID levels are available on this configuration as well, in particular the Cisco 12G SAS Modular RAID controller supports RAID levels 0, 1, 5 and 6. I’d recommend RAID level 6 for this large of a storage resource in terms of drive capacity (up to 4 TB) and the sheer number of drives coupled with rebuild times and have some spares in place. That being said, there is easily over 200 TB available for backup storage in one C3160 server. Let’s take the following figure:
The C3160 provides large amounts of backup storage with excellent connectivity

Following the last MSE blog on CleanAir, today I wish to explain how we prioritize the Mobility Service Engine’s user experience.
Listening to customers and implementing changes/features based on customer feedback has been a great strength of Cisco products. We from the Mobility Services Engine team strongly believe in this principle and make sure that we reach out to each and every customer who has provided a feedback on Cisco MSE and take their experience with MSE into consideration when designing future features and enhancements.
After analyzing the feedback we received during the MSE 7.4 release, I am pleased to announce that we have decided to implement the following two features as part of series of enhancements that we believe will improve the customer’s user experience with MSE.
Convenient Backup and Restore
Until the 7.4 release, MSE users had limited options in backing up their MSE data. The only supported option was to use the NCS FTP server as the destination for MSE data backups. Due to the limited disk capacity on NCS, as well as sharing of the disk space with other network elements, disk space limitations prevented MSE users from regularly backing up their data. If you are one of those users who always wished you could regularly backup MSE data without running into NCS disk space limitation, or if you wish you could back up your MSE data to non-NCS devices, we have some good news for you.
In the latest MSE 7.5 release, we have added the option to backup and restore your MSE data on remote FTP servers, provided there is connectivity between the MSE and the FTP server. Similar to NCS Backups, MSE data can be backed up to configured repositories (internal or external FTP servers). Love the command shell? We will also be coming up with CLI to backup MSE data. You can now start MSE backup using just a single command.
