  • The N2226 provides four x4 external mini-SAS HD connectors with 16 lanes of 12 Gbps SAS. [1] => The N2225 and N2226 SAS/SATA HBAs are low-cost, high-performance host bus adapters for high-performance connectivity between System x® servers and tapes drives and RAID storage systems.
  • [5] => For more information about the System x servers, including older servers that support the N2225 and N2226 adapters, see the following ServerProven® website: [6] => The following table lists the external storage systems that are currently offered by Lenovo that can be used with the N2225 and N2226 SAS/SATA HBAs in storage solutions.
  • When installed in a supported System x server, the adapters assume your systemâ s base warranty and any Lenovo warranty upgrade.
  • In PHP, you can use the array_unique method to remove duplicates from an array.
  • Well not exactly identical which can be removed with array_unique , but elements that are rendered obsolete by another element which contains exactly the same data and more, or sometimes just a few words are different.
