Citrix NetScaler with SSD (first impression)
April 1, 2012 Leave a comment
The Citrix NetScaler MPX 5500-7500 and 9500 appliance models now ship with Solid State Drives and says (good?)bye to the platter disk for these particulair models. This was anounced by Citrix back in februari this year: http://blogs.citrix.com/2012/02/09/citrix-netscaler-moves-to-solid-state-drives-for-future-mpx-5500-7500-and-9500-shipments/
Citrix has been using Solid State Drives in the MPX 17500/19500/21500 platforms for a longer time but they are only used for mounting the /flash volume. In the MPX 5500/7500/9500 the /flash volume is mounted on a CompactFlash Card. The (platter) Hard Disk Drive which is now being replaced by an SSD is used for the /var volume, this is where all the data and logs files are kept.
I now have a set of Citrix NetScaler MPX 5500 series which has been delivered with such Solid State Drives. The SSD in question is a Samsung 2.5” 128GB SSD (SATA3.0Gbps) which is known as a Samsung 470 series. This particulair SSD can perform sequential reads up to 250 MB/sec and sequential writes at 220 MB/sec. In comparison to the latest releases of Solid State Drives those numbers are not amazing.
